+CodeIgniter用户指南v2.2.0
 
+----
 
+
 
+编者只是网络搬运工，帮助制作成离线CHM文档，以便PHP开发者线下参考使用。
 
+
 
+原始帮助文档来自[CodeIgniter 中国](http://codeigniter.org.cn/user_guide/index.html "CodeIgniter 中g国 ")，内容版权归原始持有者所有，如有侵权，请来发email告知。
 
+
 
+感谢CodeIgniter中国，感谢EllisLab，感谢所有中文文档翻译志愿者。
 
+
 
+#脚本说明
 
+
 
+①使用Teleport离线下载CodeIgniter 中国帮助文档；
 
+
 
+②replace_htmls.exe,replace_subdir_htmls.exe是用Autohotkey写的，用来清理被Teleport离线下来的html文档(删除其中垃圾js代码段)。
 
+
 
+    注意，帮助文档子目录下的html文档（如database,general,helper目录等），    
+    请往replace_subdir_htmls.exe拖动；
 
+    帮助文档根目录下的html文档（如index.html,changelog.html,toc.html等），
 
+    请往replace_htmls.exe拖动。
 
+
 
+③CHM文档是使用微软的MS HTML Help Workshop工具来生成的，相关dll和exe位于bin目录下。ci_chm.exe是用于生成CHM帮助文档的脚本，同样也是使用Autohotkey编写。

+<li>Models do <strong>not</strong> connect automatically to the database as of this version. <a href="general/models.html">More info here</a>.</li>

+<p>Release Date: April 17, 2006</p>
 
+
 
+<ul>
 
+<li>Changed the behavior of the validation class such that if a "required" rule is NOT explicitly stated for a field then all other tests get ignored.</li>
 
+<li>Fixed a bug in the Controller class that was causing it to look in the local "init" folder instead of the main system one.</li>

+
 
+
 
+
 
+<h2>Version 1.3.1</h2>
 
+<p>Release Date: April 11, 2006</p>
 
+
 
+<ul>
 
+<li>Added a <a href="libraries/unit_testing.html">Unit Testing Library</a>.</li>
 
+<li>Added the ability to pass objects to the <strong>insert()</strong> and <strong>update()</strong>  database functions.
 
+This feature enables you to (among other things) use your  <a href="general/models.html">Model class</a> variables to run queries with. See the Models page for details.</li>
 
+<li>Added the ability to pass objects to the <a href="general/views.html">view loading function</a>: $this-&gt;load-&gt;view('my_view', <var>$object</var>);</li>
 
+<li>Added <kbd>getwhere</kbd> function to <a href="database/active_record.html">Active Record class</a>.</li>
 
+<li>Added <kbd>count_all</kbd> function to <a href="database/active_record.html">Active Record class</a>.</li>
 
+<li>Added language file for scaffolding and fixed a scaffolding bug that occurs when there are no rows in the specified table.</li>
 
+<li>Added <a href="database/queries.html">$this-&gt;db-&gt;last_query()</a>, which allows you to view your last query that was run.</li>
 
+<li>Added a new mime type to the upload class for better compatibility.</li>
 
+<li>Changed how cache files are read to prevent PHP errors if the cache file contains an XML tag, which PHP wants to interpret as a short tag.</li>
 
+<li>Fixed a bug in a couple of the active record functions (where and orderby).</li>
 
+<li>Fixed a bug in the image library when realpath() returns false.</li>
 
+<li>Fixed a bug in the Models that was preventing libraries from being used within them.</li>
 
+<li>Fixed a bug in the "exact_length" function of the validation class.</li>
 
+<li>Fixed some typos in the user guide</li>
 
+</ul>
 
+
 
+
 
+<h2>Version 1.3</h2>
 
+<p>Release Date: April 3, 2006</p>
 
+
 
+<ul>
 
+<li>Added support for <a href="index.html">Models</a>.</li>
 
+<li>Redesigned the database libraries to support additional RDBMs (Postgres, MySQLi, etc.).</li>
 
+<li>Redesigned the <a href="database/active_record.html">Active Record class</a> to enable more varied types of queries with simpler syntax, and advanced features like JOINs.</li>
 
+<li>Added a feature to the database class that lets you run <a href="database/call_function.html">custom function calls</a>.</li>
 
+<li>Added support for <a href="index.html">private functions</a> in your controllers.  Any controller function name that starts with an underscore will not be served by a URI request.</li>
 
+<li>Added the ability to pass your own initialization parameters to your <a href="index.html">custom core libraries</a> when using $this-&gt;load-&gt;library()</li>
 
+<li>Added support for running standard <a href="index.html">query string URLs</a>.  These can be optionally enabled in your config file.</li>
 
+<li>Added the ability to  <a href="index.html">specify a "suffix"</a>, which will be appended to your URLs.  For example, you could add .html to your URLs, making them appear static. This feature is enabled in your config file.</li>
 
+<li>Added a new error template for use with native PHP errors.</li>
 
+<li>Added "alternator" function in the <a href="helpers/string_helper.html">string helpers</a>.</li>
 
+<li>Removed slashing from the input class. After much debate we decided to kill this feature.</li>
 
+<li>Change the commenting style in the scripts to the PEAR standard so that IDEs and tools like phpDocumenter can harvest the comments.</li>
 
+<li>Added better class and function name-spacing to avoid collisions with user developed classes. All CodeIgniter classes are now prefixed with <dfn>CI_</dfn> and
 
+all controller methods are prefixed with <dfn>_ci</dfn> to avoid controller collisions. A list of reserved function names can be <a href="index.html">found here</a>.</li>
 
+<li>Redesigned how the "CI" super object is referenced, depending on whether PHP 4 or 5 is being run, since PHP 5 allows a more graceful way to manage objects that utilizes a bit less resources.</li>
 
+<li>Deprecated: <var>$this-&gt;db-&gt;use_table()</var> has been deprecated. Please read the <a href="database/active_record.html">Active Record</a> page for information.</li>
 
+<li>Deprecated: <var>$this-&gt;db-&gt;smart_escape_str()</var> has been deprecated. Please use this instead: <var>$this-&gt;db-&gt;escape()</var></li>
 
+<li>Fixed a bug in the exception handler which was preventing some PHP errors from showing up.</li>
 
+<li>Fixed a typo in the URI class.  $this-&gt;total_segment() should be plural: $this-&gt;total_segments()</li>
 
+<li>Fixed some typos in the default calendar template</li>
 
+<li>Fixed some typos in the user guide</li>
 
+</ul>
 
+
 
+
 
+
 
+
 
+
 
+
 
+
 
+
 
+<h2>Version 1.2</h2>
 
+<p>Release Date: March 21, 2006</p>
 
+
 
+<ul>
 
+<li>Redesigned some internal aspects of the framework to resolve scoping problems that surfaced during the beta tests. The problem was most notable when instantiating classes in your constructors, particularly if those classes in turn did work in their constructors.</li>
 
+<li>Added a global function named <a href="index.html">get_instance()</a> allowing the main CodeIgniter object to be accessible throughout your own classes.</li>
 
+<li>Added new <a href="helpers/file_helper.html">File Helper</a>:  delete_files()</li>
 
+<li>Added new <a href="helpers/url_helper.html">URL Helpers</a>:  base_url(), index_page()</li>
 
+<li>Added the ability to create your own <a href="index.html">core libraries</a> and store them in your local application directory.</li>
 
+<li>Added an <kbd>overwrite</kbd> option to the <a href="libraries/file_uploading.html">Upload class</a>, enabling files to be overwritten rather than having the file name appended.</li>
 
+<li>Added Javascript Calendar plugin.</li>
 
+<li>Added search feature to user guide.  Note: This is done using Google, which at the time of this writing has not crawled all the pages of the docs.</li>
 
+<li>Updated the parser class so that it allows tag pars within other tag pairs.</li>
 
+<li>Fixed a bug in the DB "where" function.</li>
 
+<li>Fixed a bug that was preventing custom config files to be auto-loaded.</li>
 
+<li>Fixed a bug in the mysql class bind feature that prevented question marks in the replacement data.</li>
 
+<li>Fixed some bugs in the xss_clean function</li>
 
+</ul>
 
+
 
+
 
+
 
+<h2>Version Beta 1.1</h2>

+<li>Fixed a problem that was preventing the $this-&gt;load-&gt;library function from working in constructors.</li>
 
+<li>Fixed a bug that occurred when the session class was loaded using the auto-load routine.</li>
 
+<li>Fixed a bug that can happen with PHP versions that do not support the E_STRICT constant</li>
 
+<li>Fixed a data type error in the form_radio function (form helper)</li>
 
+<li>Fixed a bug that was preventing the xss_clean function from being called from the validation class.</li>

+<li>Fixed a syntax mistake in the form_dropdown function in the Form Helper.</li>
 
+<li>Removed the "style" attributes form the form helpers.</li>

+<h1>Active Record 类</h1>
 
+
 
+
 
+<p>CodeIgniter 使用的是修改过的 Active Record 数据库模式。
 
+这种模式是以较少的程序代码来实现信息在数据库中的获取，插入，更改。
 
+有时只用一两行的代码就能完成对数据库的操作。
 
+CodeIgniter 不需要每一个数据库表拥有自己的类。它提供了一个更简单的接口。</p>
 
+
 
+<p>不只是简单，使用 Active Record 的一个主要的优点是允许你创建独立的数据库应用程序，因为查询语法是由数据库的适配器来产生的。它可以进行更安全的查询，因为系统会自动的对所有的输入值进行转义。</p>
 
+
 
+<p class="important"><strong>注意:</strong>  你如果想要写自己的查询表达式，可以在数据库配置文件中禁止这个类。同时相比 Active Record，使用核心数据库类库和适配器将会使用更少资源。<br /></p>
 
+
 
+
 
+<ul>
 
+<li><a href="#select">选择数据</a></li>
 
+<li><a href="#insert">插入数据</a></li>
 
+<li><a href="#update">更新数据</a></li>
 
+<li><a href="#delete">删除数据</a></li>
 
+<li><a href="#chaining">链式方法</a></li>
 
+<li><a href="#caching">Active Record 缓存</a></li>
 
+</ul>
 
+
 
+
 
+
 
+<a name="select">&nbsp;</a>
 
+<h1>选择数据</h1>
 
+
 
+<p>下面的函数帮助你构建 SQL <strong>SELECT</strong>语句。</p>
 
+
 
+<p><strong>备注：如果你正在使用 PHP5，你可以在复杂情况下使用链式语法。本页面底部有具体描述。</strong></p>
 
+
 
+
 
+<h2>$this-&gt;db-&gt;get();</h2>
 
+
 
+<p>运行选择查询语句并且返回结果集。可以获取一个表的全部数据。</p>
 
+
 
+<code>$query = $this-&gt;db-&gt;get('mytable');<br />
 
+<br />
 
+// Produces: SELECT * FROM mytable</code>
 
+
 
+<p>第二和第三个参数允许你设置一个结果集每页纪录数(limit)和结果集的偏移(offset)</p>
 
+
 
+<code>$query = $this-&gt;db-&gt;get('mytable', 10, 20);<br />
 
+<br />
 
+// Produces: SELECT * FROM mytable LIMIT 20, 10 (MySQL语法. 其他数据库在语法上略有不同)</code>
 
+
 
+<p>注意：第二参数是每页纪录数，第三个参数是偏移</p>
 
+<p>你会注意到上面的函数由一个变量<kbd>$query</kbd>执行，这个<kbd>$query</kbd>可以用来显示结果集。</p>
 
+
 
+<code>$query = $this-&gt;db-&gt;get('mytable');<br />
 
+<br />
 
+foreach ($query-&gt;result() as $row)<br />
 
+&#123;<br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;echo $row-&gt;title;<br />
 
+
 
+&#125;</code>
 
+
 
+<p>请访问<a href="results.html">查询结果</a>页查看详细的生成结果的方法。</p>
 
+
 
+<h2>$this-&gt;db-&gt;get_where();</h2>
 
+
 
+<p>跟上面的函数一样，只是它允许你在函数的第二个参数那里添加一个 where 从句，从而不用使用 db-&gt;where() 这个函数：</p>
 
+
 
+<code>$query = $this-&gt;db-&gt;get_where('mytable', array('id' => $id), $limit, $offset);</code>
 
+
 
+<p>请阅读下面的 where 函数了解更多。</p>
 
+<p class="important">注意: get_where() 在以前的版本中写作 getwhere()，这是已经过时的用法，现已从代码中移除 getwhere()。</p>
 
+
 
+<h2>$this-&gt;db-&gt;select();</h2>
 
+<p>允许你在SQL查询中写 SELECT 部分:</p>
 
+<p><code>
 
+$this-&gt;db-&gt;select('title, content, date');<br />
 
+<br />
 
+$query = $this-&gt;db-&gt;get('mytable');<br />
 
+<br />
 
+
 
+// Produces: SELECT title, content, date FROM mytable</code></p>
 
+<p class="important"><strong>注意:</strong> 如果你要查询表中的所有列，你可以不用写这个函数。省略后，CodeIgniter 会认为你要查询
 
+全部列(SELECT *)。</p>
 
+
 
+<p>$this-&gt;db-&gt;select() 可接受一个可选的第二个参数。如果你把它设为FALSE， CodeIgniter 将不会使用反引号保护你的字段或者表名
 
+。这在进行复合查询时很有用。</p>
 
+<p><code>$this-&gt;db-&gt;select("('SELECT SUM(payments.amount) FROM payments WHERE payments.invoice_id=4') AS amount_paid", FALSE); <br />
 
+$query = $this-&gt;db-&gt;get('mytable');<br />
 
+
 
+</code></p>
 
+<h2>$this-&gt;db-&gt;select_max();</h2>
 
+<p>为你的查询编写一个 "SELECT MAX(field)"。你可以选择性的给出第二个参数，以便重命名结果字段名。</p>
 
+<p><code>
 
+$this-&gt;db-&gt;select_max('age');<br />
 
+$query = $this-&gt;db-&gt;get('members');<br />
 
+
 
+// Produces: SELECT MAX(age) as age FROM members<br />
 
+<br />
 
+$this-&gt;db-&gt;select_max('age', 'member_age');<br />
 
+
 
+$query = $this-&gt;db-&gt;get('members');<br />
 
+// Produces: SELECT MAX(age) as member_age FROM members</code></p>
 
+
 
+<h2>$this-&gt;db-&gt;select_min();</h2>
 
+<p>为你的查询编写一个 "SELECT MIN(field)" 。与 <dfn>select_max()</dfn> 相似, 你可以选择性地给出第二个参数，用来给结果字段重命名。</p>
 
+<p><code>
 
+$this-&gt;db-&gt;select_min('age');<br />
 
+$query = $this-&gt;db-&gt;get('members');<br />
 
+
 
+// 生成: SELECT MIN(age) as age FROM members</code></p>
 
+
 
+<h2>$this-&gt;db-&gt;select_avg();</h2>
 
+<p>为你的查询编写一个 "SELECT AVG(field)" 。与 <dfn>select_max()</dfn> 相似, 你可以选择性地给出第二个参数，用来给结果字段重命名。</p>
 
+<p><code>
 
+$this-&gt;db-&gt;select_avg('age');<br />
 
+$query = $this-&gt;db-&gt;get('members');<br />
 
+// 生成: SELECT AVG(age) as age FROM members</code></p>
 
+
 
+<h2>$this-&gt;db-&gt;select_sum();</h2>
 
+<p>为你的查询编写一个 "SELECT SUM(field)" 。与 <dfn>select_max()</dfn> 相似, 你可以选择性地给出第二个参数，用来给结果字段重命名。</p>
 
+<p><code>
 
+$this-&gt;db-&gt;select_sum('age');<br />
 
+$query = $this-&gt;db-&gt;get('members');<br />
 
+// 生成: SELECT SUM(age) as age FROM members</code></p>
 
+
 
+<h2>$this-&gt;db-&gt;from();</h2>
 
+
 
+<p>允许你编写查询中的FROM部分:</p>
 
+
 
+<code>
 
+$this-&gt;db-&gt;select('title, content, date');<br />
 
+$this-&gt;db-&gt;from('mytable');<br />
 
+<br />
 
+$query = $this-&gt;db-&gt;get();<br />
 
+<br />
 
+// 生成: SELECT title, content, date FROM mytable</code>
 
+
 
+<p class="important">说明: 正如前面所说，查询中的FROM部分可以在 <dfn>$this-&gt;db-&gt;get()</dfn> 函数中指定，所以你可以根据自己的喜好来选择使用哪个方法。</p>
 
+
 
+<h2>$this-&gt;db-&gt;join();</h2>
 
+
 
+<p>允许你编写查询中的JOIN部分:</p>
 
+
 
+<code>
 
+$this-&gt;db-&gt;select('*');<br />
 
+$this-&gt;db-&gt;from('blogs');<br />
 
+$this-&gt;db-&gt;join('comments', 'comments.id = blogs.id');<br />
 
+<br />
 
+$query = $this-&gt;db-&gt;get();<br />
 
+
 
+<br />
 
+// 生成: <br />
 
+// SELECT * FROM blogs<br />
 
+// JOIN comments ON comments.id = blogs.id<br />
 
+</code>
 
+
 
+<p>如果你想要在查询中使用多个连接，可以多次调用本函数。</p>
 
+
 
+<p>如果你需要指定 JOIN 的类型，你可以通过本函数的第三个参数来指定。可选项包括：left, right, outer, inner, left outer, 以及 right outer.</p>
 
+
 
+<code>
 
+$this-&gt;db-&gt;join('comments', 'comments.id = blogs.id', <strong>'left'</strong>);<br />
 
+
 
+<br />
 
+// 生成: LEFT JOIN comments ON comments.id = blogs.id</code>
 
+
 
+<h2>$this-&gt;db-&gt;where();</h2>
 
+<p>本函数允许你使用四种方法中的一种来设置 <strong>WHERE</strong> 子句:</p>
 
+
 
+<p class="important"><strong>说明:</strong> 传递给本函数的所有值都会被自动转义，以便生成安全的查询。</p>
 
+
 
+<ol>
 
+ <li><strong>简单的 key/value 方法:</strong>
 
+
 
+ <code>$this-&gt;db-&gt;where('name', $name);
 
+ <br /><br />// 生成: WHERE name = 'Joe'
 
+ </code>
 
+ 
+ <p>请注意等号已经为你添加。</p>
 
+ 
+ <p>如果你多次调用本函数，那么这些条件会被 <var>AND</var> 连接起来:</p>
 
+
 
+ 
+ <code>$this-&gt;db-&gt;where('name', $name);<br />
 
+ $this-&gt;db-&gt;where('title', $title);<br />
 
+ $this-&gt;db-&gt;where('status', $status);
 
+ <br /><br />// WHERE name = 'Joe' AND title = 'boss' AND status = 'active'
 
+ </code>
 
+ 
+
 
+ </li>
 
+ 
+ <li><strong>自定义 key/value 方法:</strong>
 
+ 
+ <p>你可以在第一个参数中包含一个运算符，以便控制比较:</p>
 
+
 
+ 
+ <code>$this-&gt;db-&gt;where('name !=', $name);<br />
 
+ $this-&gt;db-&gt;where('id <', $id);
 
+ <br /><br />// 生成: WHERE name != 'Joe' AND id < 45</code></li>
 
+
 
+ <li><strong>关联数组方法:</strong>
 
+
 
+ <code>
 
+ $array = array('name' => $name, 'title' => $title, 'status' => $status);<br /><br />
 
+ 
+ $this-&gt;db-&gt;where($array);
 
+ <br /><br />// 生成: WHERE name = 'Joe' AND title = 'boss' AND status = 'active'
 
+ </code>
 
+
 
+ <p>使用这个方法时你也可以包含运算符:</p>
 
+
 
+ <code>
 
+
 
+ $array = array('name !=' => $name, 'id <' => $id, 'date >' => $date);<br /><br />
 
+ 
+ $this-&gt;db-&gt;where($array);</code>
 
+
 
+ </li>
 
+  <li><strong>自定义字符串:</strong>
 
+  
+  <p>你可以手动的编写子句:</p>
 
+
 
+  <code>
 
+  $where = "name='Joe' AND status='boss' OR status='active'";<br /><br />
 
+  $this-&gt;db-&gt;where($where);</code>
 
+
 
+ </li>
 
+</ol>
 
+
 
+<p>$this-&gt;db-&gt;where() 接受可选的第三个参数。如果你将它设置为 FALSE, CodeIgniter 将不会为你那些包含反勾号的字段名或表名提供保护。</p>
 
+<p><code>   $this-&gt;db-&gt;where('MATCH (field) AGAINST (&quot;value&quot;)', NULL, FALSE);<br />
 
+</code></p>
 
+
 
+<h2>$this-&gt;db-&gt;or_where();</h2>
 
+<p>本函数与上面的那个几乎完全相同，唯一的区别是本函数生成的子句是用 OR 来连接的:</p>
 
+
 
+<code>
 
+$this-&gt;db-&gt;where('name !=', $name);<br />
 
+$this-&gt;db-&gt;or_where('id >', $id);
 
+<br />
 
+<br />// 生成: WHERE name != 'Joe' OR id > 50</code>
 
+
 
+<p class="important">说明: or_where() 以前被叫作 orwhere(), 后者已经过时，现已从代码中移除 orwhere()。</p>
 
+
 
+
 
+<h2>$this-&gt;db-&gt;where_in();</h2>
 
+<p>生成一段 WHERE field IN ('item', 'item') 查询语句，如果合适的话，用 AND 连接起来。</p>
 
+
 
+<p><code>
 
+    $names = array('Frank', 'Todd', 'James');<br />
 
+    $this-&gt;db-&gt;where_in('username', $names);<br />
 
+    // 生成: WHERE username IN ('Frank', 'Todd', 'James')</code></p>
 
+
 
+<h2>$this-&gt;db-&gt;or_where_in();</h2>
 
+<p>生成一段 WHERE field IN ('item', 'item') 查询语句，如果合适的话，用 OR 连接起来。</p>

+    $names = array('Frank', 'Todd', 'James');<br />
 
+
 
+    $this-&gt;db-&gt;or_where_in('username', $names);<br />
 
+    // 生成: OR username IN ('Frank', 'Todd', 'James')</code></p>
 
+    
+<h2>$this-&gt;db-&gt;where_not_in();</h2>
 
+<p>生成一段 WHERE field NOT IN ('item', 'item') 查询语句，如果合适的话，用 AND 连接起来。</p>
 
+<p><code>
 
+    $names = array('Frank', 'Todd', 'James');<br />
 
+    $this-&gt;db-&gt;where_not_in('username', $names);<br />

+    // 生成: OR username NOT IN ('Frank', 'Todd', 'James')</code></p>
 
+
 
+<h2>$this-&gt;db-&gt;like();</h2>
 
+<p>本函数允许你生成 <strong>LIKE</strong> 子句，在做查询时非常有用。</p>
 
+
 
+<p class="important"><strong>说明:</strong> 传递给本函数的所有值都会被自动转义。</p>
 
+
 
+
 
+<ol>
 
+ <li><strong>简单 key/value 方式:</strong>
 
+
 
+ <code>$this-&gt;db-&gt;like('title', 'match');
 
+ <br /><br />// 生成: WHERE title LIKE '%match%' </code>
 
+  
+ <p>如果你多次调用本函数，那么这些条件将由 <var>AND</var> 连接起来:</p>

+ 如果你想要控制通配符(%)所出现的位置，你可以使用可选的第三个参数。可用的选项是 'before', 'after' 以及 'both' (这是默认值)。 
+ <code>$this-&gt;db-&gt;like('title', 'match', 'before');
 
+ <br />
 
+  // 生成: WHERE title LIKE '%match' <br />
 
+     <br />

+ $this-&gt;db-&gt;like('title', 'match', 'both'); <br />
 
+// 生成: WHERE title LIKE '%match%' </code> </li>
 
+
 
+如果你不想使用百分号(%)，你可以给第三个可选的参数传递一个'none'。
 
+
 
+<code>
 
+  $this-&gt;db-&gt;like('title', 'match', 'none'); <br />
 
+// Produces: WHERE title LIKE 'match'

+ 
+<h2>$this-&gt;db-&gt;or_like();</h2>
 
+<p>本函数与上面那个函数几乎完全相同，唯一的区别是多个实例之间是用 OR 连接起来的:</p>

+
 
+<code> $this-&gt;db-&gt;not_like('title', 'match');<br />
 
+<br />
 
+// WHERE title NOT LIKE '%match%</code>
 
+<h2>$this-&gt;db-&gt;or_not_like();</h2>

+<h2>$this-&gt;db-&gt;group_by();</h2>
 
+<p>允许你编写查询语句中的 GROUP BY 部分:</p>
 
+ 
+<code>$this-&gt;db-&gt;group_by("title");
 
+<br /><br />// 生成: GROUP BY title
 
+</code>
 
+
 
+<p>你也可以把多个值作为数组传递过去:</p>
 
+
 
+ 
+<code>$this-&gt;db-&gt;group_by(array("title", "date"));
 
+<br />
 
+<br />// 生成: GROUP BY title, date</code>
 
+ 
+<p class="important">说明: group_by() 曾经被称为 groupby(), 后者已经过时，现已从代码中移除 groupby()。</p>
 
+
 
+<h2> $this-&gt;db-&gt;distinct();<br />
 
+</h2>
 
+<p>为查询语句添加 &quot;DISTINCT&quot; 关键字:</p>
 
+
 
+<p><code>$this-&gt;db-&gt;distinct();<br />
 
+    $this-&gt;db-&gt;get('table');<br />
 
+        <br />
 
+    // 生成: SELECT DISTINCT * FROM table</code></p>
 
+<h2>$this-&gt;db-&gt;having();</h2>
 
+<p>允许你为你的查询语句编写 HAVING 部分。有两种语法形式，一个或两个参数都可以:</p>
 
+
 
+ 
+<code>$this-&gt;db-&gt;having('user_id = 45');
 
+<br />
 
+// 生成: HAVING user_id = 45<br />

+<p>如果你正在使用一个由CodeIgniter进行转义保护的数据库，为了避免内容转义，你可以传递可选的第三个参数，并将其设置为FALSE。</p>
 
+<p><code>$this-&gt;db-&gt;having('user_id',  45); <br />
 
+// 生成: HAVING `user_id` = 45 (在诸如MySQL等数据库中)
 
+  <br />
 
+  $this-&gt;db-&gt;having('user_id',  45, FALSE); <br />
 
+// 生成: HAVING user_id = 45</code></p>
 
+ 
+ 
+<h2>$this-&gt;db-&gt;or_having();</h2>
 
+<p>与 having() 函数几乎完全一样，唯一的区别是多个子句之间是用 &quot;OR&quot; 分隔的。</p>
 
+<h2>$this-&gt;db-&gt;order_by();</h2>
 
+<p>帮助你设置一个 ORDER BY 子句。第一个参数是你想要排序的字段名。第二个参数设置结果的顺序，可用的选项包括 <kbd>asc</kbd> (升序)或 <kbd>desc</kbd>(降序), 或 <kbd>random</kbd>(随机)。</p>
 
+
 
+ 
+<code>$this-&gt;db-&gt;order_by("title", "desc");

+ 
+<code>$this-&gt;db-&gt;order_by('title desc, name asc');
 
+<br />
 
+<br />// 生成: ORDER BY title DESC, name ASC
 
+</code>

+
 
+<code>
 
+$this-&gt;db-&gt;limit(10, 20);<br />
 
+<br />
 
+// 生成: LIMIT 20, 10 (仅限MySQL中。其它数据库有稍微不同的语法)</code>
 
+
 
+
 
+<h2>$this-&gt;db-&gt;count_all_results();</h2>
 
+
 
+<p>允许你获得某个特定的Active Record查询所返回的结果数量。可以使用Active Record限制函数，例如 where(),  or_where(), like(), or_like() 等等。范例：</p>
 
+<code>echo $this-&gt;db-&gt;count_all_results('<var>my_table</var>');<br />
 
+
 
+// 生成一个整数，例如 25<br />
 
+<br />

+    $this-&gt;db-&gt;insert('mytable'); <br />
 
+    // 得到 INSERT INTO mytable (field) VALUES (field+1)<br />
 
+    <br />
 
+    $this-&gt;db-&gt;set('field', 'field+1');<br />
 
+    $this-&gt;db-&gt;insert('mytable'); <br />
 
+
 
+    // 得到 INSERT INTO mytable (field) VALUES ('field+1')</code></p>
 
+<p>你也可以将一个关联数组传递给本函数:</p>
 
+<code>
 
+$array = array('name' => $name, 'title' => $title, 'status' => $status);<br /><br />
 
+
 
+$this-&gt;db-&gt;set($array);<br />
 
+$this-&gt;db-&gt;insert('mytable');
 
+</code>
 
+
 
+<p>或者一个对象也可以:</p>
 
+
 
+<code>
 
+/*<br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;class Myclass &#123;<br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;var  $title = 'My Title';<br />

+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;var  $date = 'My Date';<br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;&#125;<br />
 
+*/<br />
 
+<br />
 
+
 
+$object = new Myclass;<br />
 
+<br />
 
+$this-&gt;db-&gt;set($object);<br />
 
+$this-&gt;db-&gt;insert('mytable');
 
+</code>
 
+
 
+
 
+ 
+<a name="update">&nbsp;</a>
 
+<h1>更新数据</h1>
 
+ 
+<h2>$this-&gt;db-&gt;update();</h2>
 
+<p>根据你提供的数据生成并执行一条update(更新)语句。你可以将一个<strong>数组</strong>或者<strong>对象</strong>传递给本函数。这里是一个使用数组的例子:</p>
 
+
 
+<code>
 
+$data = array(<br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'title' => $title,<br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'name' => $name,<br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'date' => $date<br />
 
+
 
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;);<br />
 
+<br />
 
+$this-&gt;db-&gt;where('id', $id);<br />
 
+$this-&gt;db-&gt;update('mytable', $data);
 
+<br /><br />
 
+// 生成:<br />
 
+// UPDATE mytable <br />
 
+// SET title = '&#123;$title&#125;', name = '&#123;$name&#125;', date = '&#123;$date&#125;'<br />
 
+// WHERE id = $id</code>
 
+
 
+<p>或者你也可以传递一个对象:</p>
 
+
 
+<code>
 
+/*<br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;class Myclass &#123;<br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;var  $title = 'My Title';<br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;var  $content = 'My Content';<br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;var  $date = 'My Date';<br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;&#125;<br />
 
+*/<br />
 
+<br />
 
+
 
+$object = new Myclass;<br />
 
+<br />
 
+$this-&gt;db-&gt;where('id', $id);<br />
 
+$this-&gt;db-&gt;update('mytable', $object);
 
+<br />
 
+<br />
 
+// 生成:<br />
 
+// UPDATE mytable <br />
 
+// SET title = '&#123;$title&#125;', name = '&#123;$name&#125;', date = '&#123;$date&#125;'<br />
 
+// WHERE id = $id</code>
 
+
 
+
 
+<p class="important"><strong>说明:</strong> 所有值都会被自动转义，以便生成安全的查询。</p>
 
+ 
+<p>你会注意到 <dfn>$this-&gt;db-&gt;where()</dfn> 函数的用法，它允许你设置 WHERE 子句。你可以有选择性地将这一信息直接以字符串的形式传递给 update 函数:</p>
 
+
 
+<code>$this-&gt;db-&gt;update('mytable', $data, "id = 4");</code>
 
+
 
+<p>或者是一个数组:</p>
 
+
 
+<code>$this-&gt;db-&gt;update('mytable', $data, array('id' => $id));</code>
 
+ 
+<p>在进行更新时，你还可以使用上面所描述的 <dfn>$this-&gt;db-&gt;set()</dfn> 函数。</p>
 
+
 
+<h2>$this-&gt;db-&gt;update_batch();</h2>
 
+<p>生成一条update命令是以你提供的数据为基础的，并执行查询。你可以传递一个数组或对象的参数给update_batch()函数。下面是一个使用一个数组作为参数的示例：Generates an update string based on the data you supply, and runs the query. You can either pass an
 
+<strong>array</strong> or an <strong>object</strong> to the function.  Here is an example using an array:</p>
 
+
 
+<code>
 
+$data = array(<br/>
 
+&nbsp;&nbsp;&nbsp;array(<br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'title' => 'My title' ,<br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'name' => 'My Name 2' ,<br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'date' => 'My date 2'<br />
 
+&nbsp;&nbsp;&nbsp;),<br />
 
+&nbsp;&nbsp;&nbsp;array(<br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'title' => 'Another title' ,<br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'name' => 'Another Name 2' ,<br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'date' => 'Another date 2'<br />
 
+&nbsp;&nbsp;&nbsp;)<br/>
 
+);<br />
 
+<br />
 
+$this-&gt;db-&gt;update_batch('mytable', $data, 'title');
 
+<br /><br />
 
+// Produces: <br />
 
+// UPDATE `mytable` SET `name` = CASE<br />
 
+// WHEN `title` = 'My title' THEN 'My Name 2'<br />
 
+// WHEN `title` = 'Another title' THEN 'Another Name 2'<br />
 
+// ELSE `name` END,<br />
 
+// `date` = CASE <br />
 
+// WHEN `title` = 'My title' THEN 'My date 2'<br />
 
+// WHEN `title` = 'Another title' THEN 'Another date 2'<br />
 
+// ELSE `date` END<br />
 
+// WHERE `title` IN ('My title','Another title')</code>
 
+
 
+<p>参数1:表名 参数2:如上所示的二维数组 参数3:键名.</p>
 
+
 
+<p class="important"><strong>提示:</strong> 所有的值都会自动进行安全性过滤.</p>
 
+
 
+
 
+<a name="delete">&nbsp;</a>
 
+<h1>删除数据</h1>
 
+
 
+
 
+ 
+
 
+<h2>$this-&gt;db-&gt;delete();</h2>
 
+<p>生成并执行一条DELETE(删除)语句。</p>
 
+
 
+<code>
 
+$this-&gt;db-&gt;delete('mytable', array('id' => $id));
 
+<br /><br />
 
+// 生成:<br />
 
+// DELETE FROM mytable <br />
 
+// WHERE id = $id</code>
 
+
 
+<p>第一个参数是表名，第二个参数是where子句。你可以不传递第二个参数，使用 <dfn>where()</dfn> 或者 <dfn>or_where()</dfn> 函数来替代它:</p>
 
+
 
+<p><code> $this-&gt;db-&gt;where('id', $id);<br />
 
+    $this-&gt;db-&gt;delete('mytable'); <br />
 
+    <br />
 
+    // 生成:<br />
 
+    // DELETE FROM mytable <br />
 
+    // WHERE id = $id</code></p>
 
+
 
+<p>如果你想要从一个以上的表中删除数据，你可以将一个包含了多个表名的数组传递给delete()函数。</p>
 
+<p><code>$tables = array('table1', 'table2', 'table3');<br />
 
+$this-&gt;db-&gt;where('id', '5');<br />
 
+$this-&gt;db-&gt;delete($tables);</code></p>
 
+<p>如果你想要删除表中的全部数据，你可以使用 <dfn>truncate()</dfn> 函数，或者 <dfn>empty_table()</dfn> 函数。</p>
 
+<p class="important"><strong>说明：</strong>delete方法貌似现在没有办法接收排序参数</p>
 
+  <p>假设我想删除早期的用户登录日志信息，我的语法可能会是根据登录时间正序排列，然后跟上limit已经有的总日志条数减去想保留的条数，delete方法没有这个参数用来接收，那么我只能直接使用query传递我的sql了</p>
 
+
 
+<h2>$this-&gt;db-&gt;empty_table();</h2>
 
+<p>生成并执行一条DELETE(删除)语句。<code>    $this-&gt;db-&gt;empty_table('mytable'); <br />
 
+    <br />
 
+// 生成<br />
 
+// DELETE FROM mytable</code></p>
 
+<h2>$this-&gt;db-&gt;truncate();</h2>
 
+
 
+<p>生成并执行一条TRUNCATE(截断)语句。</p>
 
+<code> $this-&gt;db-&gt;from('mytable'); <br />
 
+$this-&gt;db-&gt;truncate(); <br />
 
+// 或 <br />
 
+$this-&gt;db-&gt;truncate('mytable'); <br />
 
+
 
+<br />
 
+// 生成:<br />
 
+// TRUNCATE TABLE mytable <br />
 
+</code>
 
+<p class="important"><strong>说明:</strong> 如果 TRUNCATE 命令不可用，truncate() 将会以 &quot;DELETE FROM table&quot; 的方式执行。</p>
 
+  
+<h1><a name="chaining">&nbsp;</a>链式方法</h1>
 
+
 
+<p>链式方法允许你以连接多个函数的方式简化你的语法。考虑一下这个范例:</p>
 
+
 
+<code>
 
+<dfn>$this-&gt;db</dfn><kbd>-&gt;</kbd><var>select</var>('title')<kbd>-&gt;</kbd><var>from</var>('mytable')<kbd>-&gt;</kbd><var>where</var>('id', $id)<kbd>-&gt;</kbd><var>limit</var>(10, 20);<br />
 
+<br />
 
+
 
+$query = $this-&gt;db-&gt;get();</code>
 
+
 
+<p class="important"><strong>说明:</strong> 链式方法只能在PHP 5下面运行。</p>
 
+
 
+<p>&nbsp;</p>
 
+
 
+<h1><a name="caching">&nbsp;</a>Active Record 缓存</h1>
 
+
 
+<p>尽管不是 &quot;真正的&quot; 缓存，Active Record 允许你将查询的某个特定部分保存(或&quot;缓存&quot;)起来，以便在你的脚本执行之后重用。一般情况下，当一次Active Record调用结束，所有已存储的信息都会被重置，以便下一次调用。如果开启缓存，你就可以使信息避免被重置，方便你进行重用。</p>
 
+
 
+<p>缓存调用是累加的。如果你调用了两次有缓存的 select()，然后再调用两次没有缓存的 select()，这会导致 select() 被调用4次。有三个可用的缓存函数:</p>
 
+
 
+<h2>$this-&gt;db-&gt;start_cache()</h2>
 
+<p>本函数必须被用来开启缓存。所有类型正确的(下面给出了支持的查询类型) Active Record 查询都会被存储起来供以后使用。</p>
 
+<h2>$this-&gt;db-&gt;stop_cache()</h2>
 
+<p>本函数可以被用来停止缓存。</p>
 
+<h2>$this-&gt;db-&gt;flush_cache()</h2>
 
+<p>本函数从Active Record 缓存中删除全部项目。</p>
 
+<p>这里是一个使用范例:</p>
 
+<p><code>$this-&gt;db-&gt;start_cache();<br />
 
+$this-&gt;db-&gt;select('field1');<br />
 
+$this-&gt;db-&gt;stop_cache();<br /><br />
 
+$this-&gt;db-&gt;get('tablename');<br />
 
+<br />
 
+//Generates: SELECT `field1` FROM (`tablename`)<br />
 
+<br />
 
+$this-&gt;db-&gt;select('field2');<br />
 
+$this-&gt;db-&gt;get('tablename');<br />
 
+<br />
 
+//Generates:  SELECT `field1`, `field2` FROM (`tablename`)<br />
 
+<br />
 
+$this-&gt;db-&gt;flush_cache();<br />
 
+<br />
 
+$this-&gt;db-&gt;select('field2');<br />
 
+$this-&gt;db-&gt;get('tablename');<br />
 
+<br />
 
+//Generates:  SELECT `field2` FROM (`tablename`)</code></p>
 
+
 
+<p class="important"> <strong>说明:</strong> 下列语句能够被缓存: select, from, join, where, like, group_by, having, order_by, set</p><p>&nbsp;</p>

+<h1>数据库缓存类</h1>
 
+
 
+<p>数据库缓存类允许你把数据库查询结果保存在文本文件中以减少数据库访问。</p>
 
+
 
+<p class="important"><strong>重要提示：</strong>&nbsp; 本类在激活后会随数据库驱动自动初始化。<b>切勿</b>手动加载。<br /><br />
 
+
 
+<strong>另：</strong>&nbsp; 并非所有查询结果都能被缓存。请仔细阅读本页内容。</p>
 
+
 
+<h2>激活缓存</h2>
 
+
 
+<p>激活缓存需要三步：</p>
 
+
 
+<ul>
 
+<li>在服务器上创建一个可写的目录以便保存缓存文件。</li>
 
+<li>在文件 <dfn>application/config/database.php</dfn> 中<dfn>$db['xxxx']['cachedir'] </dfn>设置其目录。</li>
 
+
 
+<li>激活缓存特性，可以在文件 <dfn>application/config/database.php</dfn> 中设置全局选项<dfn>$db['xxxx']['cache_on']='TRUE'</dfn>，也可以用以本页下面的方法手动设置。</li>
 
+</ul>
 
+
 
+<p>一旦被激活，每一次含有数据库查询的页面被加载时缓存就会自动发生。</p>
 
+
 
+
 
+<h2>缓存如何工作？</h2>
 
+
 
+<p>当页面被浏览时CodeIgniter的查询缓存系统能够动态执行。如果缓存特性被激活，那么在此页面首次被加载时，数据库查询的结果对象将会被序列化并保存在你服务器的文本文件中。而页面再次被加载时缓存文件将会替代数据库查询。如此，在被缓存的页面中，你的数据库使用率会降至0。</p>
 
+
 
+<p>只有 <dfn>读类型(read-type)</dfn> (SELECT) 查询会被缓存，因为只有这种查询会产生结果集。
 
+<dfn>写类型(Write-type)</dfn> (INSERT, UPDATE, 等等) 查询，因为不会产生结果集，故缓存系统不对之进行缓存。</p>
 
+
 
+<p>缓存文件<b>不会</b>过期，除非你删掉，否则任何被缓存了的查询会一直存在。缓存系统允许你按页面清除，或把所有缓存都清除掉。一般来说，你可以在某些事件(比如向数据库添加了数据)发生时用下面的函数来清除缓存。</p>
 
+
 
+<h2>缓存能够提升站点的性能吗？</h2>
 
+
 
+<p>缓存能否获得性能增益，取决于很多因素。如果您有一个负荷很少而高度优化的数据库，你可能不会看到性能提升。
 
+如果您的数据库正在大量使用,您可能会看到缓存后带来的性能提升，前提是你的文件系统是并没有太多开销。(这里'CI中国社区'要补充一点:生成缓存以及索引缓存等一系列操作(缓存系统自身运算)也是存在开销的.) Remember that caching simply changes how your information is retrieved, shifting it from being a database
 
+operation to a file-system one.</p>
 
+
 
+<p>在一些集群服务器环境，会出现这样的情况，因为文件系统的操作太过频繁,缓存无法正确生成。
 
+在单一的服务器在共享的环境，高速缓存可能会是有益的。是否能有性能上的提升应还取决于您的数据库。这要看您的具体情况.</p>
 
+
 
+<h2>缓存文件如何存储？</h2>
 
+
 
+<p>CodeIgniter拥有每个 places the result of EACH query into its own cache file.  Sets of cache files are further organized into
 
+sub-folders corresponding to your controller functions.  To be precise, the sub-folders are named identically to the
 
+first two segments of your URI (the controller class name and function name).</p>
 
+<p>CI把每次查询的结果放置在自己的缓存文件里。根据你的控制器函数，缓存文件集将被进一步组织到子目录中。准确的话，子目录的名称由你的URI的前两段（控件器类名和函数名）决定</p>
 
+
 
+<p>For example, let's say you have a controller called <dfn>blog</dfn> with a function called <dfn>comments</dfn> that
 
+contains three queries.  The caching system will create a cache folder
 
+called <kbd>blog+comments</kbd>, into which it will write three cache files.</p>
 
+<p>
 
+例如，假设你有一个控制器<dfn>blog</dfn>和一个<dfn>comments</dfn>函数，这个函数包括三个查询。缓存系统将创建一个叫做blog+comments的目录并在这个目录里创建三个缓存文件。
 
+</p>
 
+
 
+<p>If you use dynamic queries that change based on information in your URI (when using pagination, for example), each instance of
 
+the query will produce its own cache file.  It's possible, therefore, to end up with many times more cache files than you have
 
+queries.</p>
 
+<p>当你根据URI上的信息动态查询时（例如使用分页），每次查询的实例将创建自己的缓存文件。因此，经过很多次查询后，缓存文件的个数可能比你查询的次数还多。</p>
 
+
 
+<h2>管理您的缓存文件</h2>
 
+
 
+<p>由于缓存文件不会过期，您需要在您的应用程序中写入删除缓存操作的代码。例如，假设您有一个博客，让用户发表评论。每当有新的评论被提交 您一定希望在某个控制器的方法中删除缓存文件与控制器的功能 .  你会发现如下两个删除功能的介绍，可以帮助您清除数据.</p>
 
+
 
+
 
+<h2>并非所有的数据库方法都带缓存</h2>
 
+
 
+<p>最后，我们需要指出的是，由于对象是缓存 是一个简化版本的全部结果对象。出于这一原因，一些不具备数据查询结果的方法不被缓存 如 插入 更新。.</p>
 
+
 
+<p>下列方法不能和缓存搭配使用:</p>
 
+
 
+<ul>
 
+<li>num_fields()</li>
 
+<li>field_names()</li>
 
+<li>field_data()</li>
 
+<li>free_result()</li>
 
+</ul>
 
+
 
+<p>同样, the two database resources (result_id and conn_id) are not available when caching, since result resources only
 
+pertain to run-time operations.</p>
 
+
 
+
 
+<br />
 
+
 
+<h1>函数参考</h1>
 
+
 
+
 
+
 
+<h2>$this-&gt;db-&gt;cache_on()&nbsp; / &nbsp; $this-&gt;db-&gt;cache_off()</h2>
 
+
 
+<p>可手动设置缓存开关。如果您想保留某些查询不被缓存 这个功能就十分有用。例如：:</p>
 
+
 
+<code>
 
+// 打开缓存开关<br />
 
+$this-&gt;db-&gt;cache_on();<br />
 
+$query = $this-&gt;db-&gt;query("SELECT * FROM mytable");<br />
 
+<br />
 
+// 使下面这条查询不被缓存<br />
 
+$this-&gt;db-&gt;cache_off();<br />
 
+$query = $this-&gt;db-&gt;query("SELECT * FROM members WHERE member_id = '$current_user'");<br />
 
+

+<h2>$this-&gt;db-&gt;cache_delete()</h2>
 
+
 
+<p>删除缓存文件与特定网页。如果你需要清除缓存后，更新您的数据库.</p>
 
+
 
+<p>缓存系统会在缓存存放目录中建立与被访问的URL所对应的子目录,同时把缓存文件存放在那个子目录中.缓存主目录就是您在<dfn>application/config/database.php</dfn> 里面设置的缓存目录.  例如, 如果您正在浏览地址为
 
+<dfn>example.com/index.php/blog/comments</dfn>的页面, 缓存系统会把所有生成的缓存文件放进一个以
 
+<dfn>blog+comments</dfn>做为名称的文件夹里.  如果您要删除关于刚才提到的这个例子与之对应的缓存文件 需要执行以下代码:</p>
 
+
 
+<code>$this-&gt;db-&gt;cache_delete('/blog', 'comments');</code>
 
+<font color='red'><strong>注意，手册上写的是 $this-&gt;db-&gt;cache_delete('blog', 'comments');但根据实际测试应该在控制器名字前加斜杠'/'才能正确执行。</strong></font>
 
+
 
+<p>如果您不使用任何参数,目前的URI设置将决定什么时候应该清除/更新 该缓存.</p>
 
+
 
+
 
+<h2>$this-&gt;db-&gt;cache_delete_all()</h2>
 
+
 
+<p>清除所有所有的缓存文件。例子:</p>
 
+
 
+<code>$this-&gt;db-&gt;cache_delete_all();</code><p>&nbsp;</p>

+<h1>自定义函数调用</h1>
 
+
 
+<h2>$this-&gt;db-&gt;call_function();</h2>
 
+
 
+<p>这个函数可以允许你用一个独立的方法来调用一些 CodeIgniter 中没有定义的PHP数据库函数. 举个例子, 比如说你要调用 <dfn>mysql_get_client_info()</dfn> 这个 CodeIgniter 中并<strong>没有</strong>定义的函数, 你可以这样:</p>
 
+
 
+<code>$this-&gt;db-&gt;call_function('<var>get_client_info</var>');</code>
 
+
 
+<p>你必须提供一个<strong>没有</strong> <var>mysql_</var> 前缀的函数名来作为第一个参数, 这个前缀会根据当前正在使用的数据库类型来自动添加.
 
+这样允许你可以在不同的数据库平台下使用同一个函数来操作. 当然了, 并不是所有数据库使用的函数都是一样的, 那么这个函数还是非常易用的.</p>
 
+
 
+<p>任何你需要添加的其它参数都放在第一个参数后面.</p>
 
+
 
+<code>$this-&gt;db-&gt;call_function('<var>some_function</var>', $param1, $param2, etc..);</code>
 
+
 
+
 
+<p>通常情况下, 你会需要提供一个 connection ID 或是一个 result ID, connection ID 可以这样来获得:</p>
 
+
 
+<code>$this-&gt;db-&gt;conn_id;</code>
 
+
 
+<p>result ID 则包含在一个结果集(result object)中, 你可以这样来获得它:</p>
 
+
 
+<code>$query = $this-&gt;db-&gt;query("SOME QUERY");<br />
 
+
 
+<br />
 
+<var>$query-&gt;result_id;</var></code><p>&nbsp;</p>

+<h1>数据库配置</h1>
 
+
 
+<p>CodeIgniter 有一个配置文件让你存放数据库连接值（username:用户名，password:密码，database name:数据库名，等等..）.
 
+该配置文件位于 <samp>application/config/database.php</samp>. 你也可以通过放置不同的<strong>database.php</strong>文件到特定的环境配置文件夹里来设置特定<a href="../libraries/config.html">环境</a>的数据库连接值.
 
+
 
+<p>配件文件存放在一个如下格式的一个多维数组里:</p>
 
+
 
+<code>$db['default']['hostname'] = "localhost";<br />
 
+$db['default']['username'] = "root";<br />
 
+$db['default']['password'] = "";<br />
 
+$db['default']['database'] = "database_name";<br />
 
+$db['default']['dbdriver'] = "mysql";<br />
 
+$db['default']['dbprefix'] = "";<br />
 
+$db['default']['pconnect'] = TRUE;<br />
 
+
 
+$db['default']['db_debug'] = FALSE;<br />
 
+$db['default']['cache_on'] = FALSE;<br />
 
+$db['default']['cachedir'] =  &quot;&quot;;<br />
 
+$db['default']['char_set'] = "utf8";<br />
 
+$db['default']['dbcollat'] = "utf8_general_ci";<br />
 
+$db['default']['swap_pre'] = "";<br />
 
+$db['default']['autoinit'] = TRUE;<br />
 
+$db['default']['stricton'] = FALSE;</code>
 
+
 
+<p>我们使用多维数组的原因是为了让你随意的存储多个连接值的设置。举例：如果你运行多个环境（development：开发、production：生产、test：测试 等等..），你能为每个环境建立独立的连接组，并在组直接进行切换。举例，设置一个"test"环境，你可以这样做：</p>
 
+
 
+<code>$db['test']['hostname'] = "localhost";<br />
 
+
 
+$db['test']['username'] = "root";<br />
 
+$db['test']['password'] = "";<br />
 
+$db['test']['database'] = "database_name";<br />
 
+$db['test']['dbdriver'] = "mysql";<br />
 
+$db['test']['dbprefix'] = "";<br />
 
+$db['test']['pconnect'] = TRUE;<br />
 
+$db['test']['db_debug'] = FALSE;<br />
 
+$db['test']['cache_on'] = FALSE;<br />
 
+$db['test']['cachedir'] =  &quot;&quot;;<br />
 
+$db['test']['char_set'] = "utf8";<br />
 
+$db['test']['dbcollat'] = "utf8_general_ci";<br />
 
+$db['test']['swap_pre'] = "";<br />
 
+$db['test']['autoinit'] = TRUE;<br />
 
+$db['test']['stricton'] = FALSE;</code>
 
+
 
+<p>那么，告诉系统使用"test"组，你可以设置位于配置文件中的变量：</p>
 
+
 
+<code>$active_group = "test";</code>
 
+
 
+<p>注意: "test"的名字是任意的，这可以让你自由设置，我们的主要连接默认使用"default"这个名字，当然，您可以基于您的项目为它起一个更有意义的名字。</p>
 
+
 
+<h3>Active Record</h3>
 
+
 
+<p> <a href="active_record.html">Active Record 类</a> 可以通过数据库配置文件里的$active_record变量进行全局的设定（允许/禁止 TRUE/FALSE (boolean)）. 如果你不用这个类，那么你可以通过将这个变量值设置成FALSE来减少在数据库类初始化时对电脑资源的消耗。</p>
 
+
 
+<code>$active_record = TRUE;</code>
 
+
 
+<p class="important"><strong>注意：</strong> 一些CodeIgniter的类，例如Sessions，在执行一些函数的时候需要Active Records的支持。</p>
 
+
 
+<h3>参数解析:</h3>
 
+
 
+<ul>
 
+<li><strong>hostname</strong> - 数据库的主机名，通常位于本机，可以表示为 "localhost".</li>
 
+<li><strong>username</strong> - 需要连接到数据库的用户名.</li>
 
+<li><strong>password</strong> - 登陆数据库的密码.</li>
 
+
 
+<li><strong>database</strong> - 你需要连接的数据库名.</li>
 
+<li><strong>dbdriver</strong> - 数据库类型。如：mysql、postgres、odbc 等。必须为小写字母。</li>
 
+<li><strong>dbprefix</strong> - 当运行<a href="active_record.html">Active Record</a>查询时数据表的前缀,它允许在一个数据库上安装多个CodeIgniter程序.</li>
 
+<li><strong>pconnect</strong> - TRUE/FALSE (boolean) - 使用持续连接.</li>
 
+
 
+<li><strong>db_debug</strong> - TRUE/FALSE (boolean) - 显示数据库错误信息.</li>
 
+<li><strong>cache_on</strong> - TRUE/FALSE (boolean) - 数据库查询缓存是否开启，详情请见<a href="caching.html">数据库缓存类</a>。</li>
 
+<li><strong>cachedir</strong> - 数据库查询缓存目录所在的服务器绝对路径。</li>
 
+<li><strong>char_set</strong> - 与数据库通信时所使用的字符集。</li>
 
+<li><strong>dbcollat</strong> - 与数据库通信时所使用的字符规则。<p class="important"><strong>提示:</strong> 就MYSQL或MYSQLi数据库而言，如果服务器运行环境PHP版本小于5.2.3、MYSQL版本小于5.0.7，那么该项设置仅被用来备份（由数据库维护类DB Forge所创建查询）。如果使用多字节字符集并且使用低版本PHP环境中不兼容的mysql_real_escape_string()函数，它将使网站更容易受到SQL注入的危险。</p></li>
 
+<li><strong>swap_pre</strong> - 替换默认的dbprefix表前缀，该项设置对于分布式应用是非常有用的，你可以在查询中使用由最终用户定制的表前缀。</li>
 
+  <p class="important"><strong>曜日晨阳注:  </strong>如果设置了 $db['default']['dbprefix'] 的值
 
+同时也设置了 $db['default']['swap_pre'] 的值，则会将查询代码中和$db['default']['swap_pre'] 的值一致的字符替换成 $db['default']['dbprefix'] 的值，如果没有设置 $db['default']['swap_pre'] 值，就直接在数据库表名前面加上 $db['default']['dbprefix'] 值。</p>
 
+<li><strong>autoinit</strong> - 当数据库类库(database library)被载入的时候是否需要自动连接数据库，如果设置为FALSE，将在首次查询前进行连接。</li>
 
+<li><strong>stricton</strong> - TRUE/FALSE (boolean) - 是否强制使用 "Strict Mode" 连接, 在开发程序时，使用 strict SQL 是一个好习惯。</li>
 
+<li><strong>port</strong> - 数据库端口号.  要使用这个值，你应该添加一行代码到数据库配置数组。<code>$db['default']['port'] =  5432;</code></li>
 
+</ul>
 
+
 
+<p class="important"><strong>提示:</strong> 并不是所有的值都是必须的,这取决与您所使用的数据库平台,如(MySQL, Postgres, 等.)
 
+例如, 当你使用SQLite时,你不需要提供username 或 password, 数据库名字就是您数据库文件的路径. 以上内容假定您使用的是 MySQL 数据库.</p><p>&nbsp;</p>

+<h1>连接你的数据库</h1>
 
+
 
+<p>有两种方法连接数据库：</p>
 
+
 
+<h2>自动连接</h2>
 
+
 
+<p> “自动连接” 功能将在每一个页面加载时被自动实例化数据库类。要启用“自动连接”，可在<kbd>application/config/autoload.php</kbd>中的 library 数组里添加 <var>database</var>：</p>
 
+<code>$autoload['libraries'] = array('database');</code>
 
+
 
+<h2>手动连接</h2>
 
+
 
+<p>如果仅仅是一部分页面要求数据库连接，你可以在你有需要的函数里手工添加如下代码或者在你的类里手工添加以供该类使用。</p>
 
+
 
+<code>$this-&gt;load-&gt;database();</code>
 
+
 
+<p class="important">如果以上函数的第一个参数<strong>没有</strong>任何信息，它将会在系统指定的数据库配置文件中寻找，对多数人而言，这是一个首选的方法。</p>
 
+
 
+<h3>可用的参数</h3>
 
+
 
+<ol>
 
+ <li>数据库连接值，用数组或DSN字符串传递。</li>
 
+ <li>是否返回连接ID，TRUE/FALSE (boolean),默认值为FALSE (参阅下面的“连接多数据库”)。</li>
 
+    <li>是否启用 Active Record 类,TRUE/FALSE (boolean),默认值为 NULL。如有疑问，请查看<kbd>/system/core/Loader.php</kbd>的<var>database()</var>方法</li>
 
+</ol>
 
+
 
+
 
+<h3>手动连接到一个数据库</h3>
 
+
 
+<p>函数的第一个参数能够从你的配置文件中<strong>自由的</strong>指定你自定义的详细的数据库配置信息。或者你甚至可以不通过指定的配置文件来提交数据库的连接属性。
 
+样例：</p>
 
+
 
+<p>要从你的配置文件中选择一个指定的数组你可以这么做：</p>
 
+
 
+<code>$this-&gt;load-&gt;database('<samp>group_name</samp>');</code>
 
+
 
+<p><samp>group_name</samp>指的是存在于你的配置文件中的带有数据库连接信息的数组的名字。</p>
 
+
 
+
 
+<p>要手动连接你要求的数据库你可以通过定义以下数组来实现：</p>
 
+
 
+<code>$config['hostname'] = "localhost";<br />
 
+
 
+$config['username'] = "myusername";<br />
 
+$config['password'] = "mypassword";<br />
 
+$config['database'] = "mydatabase";<br />
 
+$config['dbdriver'] = "mysql";<br />
 
+$config['dbprefix'] = "";<br />
 
+$config['pconnect'] = FALSE;<br />
 
+$config['db_debug'] = TRUE;<br />
 
+$config['cache_on'] = FALSE;<br />
 
+$config['cachedir'] = "";<br />
 
+$config['char_set'] = "utf8";<br />
 
+$config['dbcollat'] = "utf8_general_ci";<br />
 
+<br />
 
+
 
+$this-&gt;load-&gt;database(<samp>$config</samp>);</code>
 
+
 
+<p>想得到每一个配置属性的详细信息可点击 <a href="configuration.html">这里</a>.</p>
 
+
 
+<p>或者你可以以DSN的方式提交数据库配置信息。 DSN必然通过以下方式实现：</p>
 
+
 
+<code>$dsn = 'dbdriver://username:password@hostname/database';<br />
 
+<br />
 
+$this-&gt;load-&gt;database(<samp>$dsn</samp>);</code>
 
+
 
+<p>当用 DSN 字符串连接时，要覆盖配置默认值，则添加配置变量为查询字符串。</p>
 
+
 
+<code>$dsn = 'dbdriver://username:password@hostname/database?char_set=utf8&amp;dbcollat=utf8_general_ci&amp;cache_on=true&amp;cachedir=/path/to/cache';<br />
 
+<br />
 
+$this-&gt;load-&gt;database(<samp>$dsn</samp>);</code>
 
+
 
+<p class="important">当你的dbdriver值为<strong>mysqli</strong>来进行远程连接时，切记要指定一个参数<strong>Port</strong>为远程mysql端口</p>
 
+
 
+<h2>连接多数据库</h2>
 
+
 
+<p>如果你需要同时连接多于一个的数据库，你可以用以下方式来实现：</p>
 
+
 
+
 
+<code>$DB1 = $this-&gt;load-&gt;database('group_one', TRUE);<br />
 
+$DB2 = $this-&gt;load-&gt;database('group_two', TRUE);
 
+</code>
 
+
 
+<p>注意：改变 "group_one" 和 "group_two" 为你指定了连接属性的组名 (或者通过上边说过的连接数组的数组名)。</p>
 
+
 
+<p>通过设置函数的第二个参数为TRUE(boolean)来返回一个数据库对象。</p>
 
+
 
+<div class="important">
 
+<p>当你使用这种方法，你将用对象名来执行操作命令而不是用户向导模式，也就是说，你将用以下方式执行数据库操作：</p>
 
+
 
+<p>$DB1-&gt;query();<br />$DB1-&gt;result();<br /> etc...</p>
 
+
 
+<p>而不是：</p>
 
+
 
+<p>$this-&gt;db-&gt;query();<br />$this-&gt;db-&gt;result();<br /> etc...</p>
 
+
 
+<br /><p>译注：要连接多个数据库请先设置 config/database.php 中的 $db['xxxxxx']['pconnect'] = FALSE; 这是 mysql_pconnect() 造成的问题，和 CI 无关。</p>
 
+
 
+</div>
 
+
 
+<h2>重新连接 / 保持连接有效</h2>
 
+
 
+<p>当你正在进行一些重量级的PHP操作(例如处理图片)时，如果超出了数据库服务器的空闲超时限度，你应该考虑在执行更多查询之前使用<dfn>reconnect()</dfn>方法来向服务器发送ping命令，这样可以优雅地保持或重新建立连接。</p>
 
+
 
+<code>$this-&gt;db-&gt;reconnect();</code>
 
+
 
+<h2>手动关闭连接</h2>
 
+
 
+<p>虽然CodeIgniter 可以智能的管理并自动关闭数据库连接，你仍可以用下面的方法显式的关闭掉。</p>
 
+
 
+<code>$this-&gt;db-&gt;close();</code><p>&nbsp;</p>

+<h1>数据库快速入门例子代码</h1>
 
+
 
+<p>下面的内容将简单说明怎样使用数据库。更详细的信息请阅读各个函数的单独介绍页面。</p>
 
+
 
+
 
+<h2>初始化数据库类</h2>
 
+
 
+<p>下面的代码将依据你的<a href="configuration.html">数据库配置</a>载入并初始化数据库类:</p>
 
+
 
+<code>$this->load->database();</code>
 
+
 
+<p>一旦被载入，你可以在任何地方像这样使用它：</p>
 
+
 
+<p>注意: 如果你的所有页面均要求初始化数据库类，你可以让它自动加载。详见 <a href="connecting.html">数据库连接</a>。</p>
 
+
 
+
 
+<h2>多结果标准查询（对象形式）</h2>
 
+
 
+<code>$query = $this->db->query('SELECT name, title, email FROM my_table');<br />
 
+<br />
 
+foreach ($query->result() as $row)<br />
 
+&#123;<br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;echo $row->title;<br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;echo $row->name;<br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;echo $row->email;<br />
 
+
 
+&#125;<br />
 
+<br />
 
+echo 'Total Results: ' . $query->num_rows();
 
+</code>
 
+
 
+<p>上面的<dfn>result()</dfn>函数返回一个<strong>对象</strong>的数组。例如：$row->title</p>
 
+
 
+
 
+<h2>多结果标准查询（数组形式）</h2>
 
+
 
+<code>$query = $this->db->query('SELECT name, title, email FROM my_table');<br />
 
+<br />
 
+foreach ($query->result_array() as $row)<br />
 
+&#123;<br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;echo $row['title'];<br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;echo $row['name'];<br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;echo $row['email'];<br />
 
+&#125;</code>
 
+
 
+<p>上面的<dfn>result_array()</dfn>函数返回一个带下标的数组。例如：$row['title']</p>
 
+
 
+
 
+<h2>测试查询结果</h2>
 
+
 
+<p>如果你的查询可能不返回结果，我们建议你先使用 <dfn>num_rows()</dfn>函数来测试:</p>
 
+
 
+<code>
 
+$query = $this->db->query("YOUR QUERY");<br />
 
+<br />
 
+if ($query->num_rows() > 0)<br />
 
+&#123;<br />
 
+&nbsp;&nbsp;&nbsp;foreach ($query->result() as $row)<br />
 
+&nbsp;&nbsp;&nbsp;&#123;<br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;echo $row->title;<br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;echo $row->name;<br />
 
+
 
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;echo $row->body;<br />
 
+&nbsp;&nbsp;&nbsp;&#125;<br />
 
+&#125;
 
+</code>
 
+
 
+
 
+
 
+
 
+<h2>单结果标准查询（对象形式）</h2>
 
+
 
+<code>$query = $this->db->query('SELECT name FROM my_table LIMIT 1');<br />
 
+<br />
 
+$row = $query->row();<br />
 
+
 
+echo $row->name;<br />
 
+</code>
 
+
 
+<p>上面的<dfn>row()</dfn>函数返回一个 <strong>对象</strong>。例如：$row->name</p>
 
+
 
+
 
+<h2>单结果标准查询（数组形式）</h2>
 
+
 
+<code>$query = $this->db->query('SELECT name FROM my_table LIMIT 1');<br />
 
+
 
+<br />
 
+$row = $query->row_array();<br />
 
+echo $row['name'];<br />
 
+</code>
 
+
 
+<p>上面的<dfn>row_array()</dfn>函数返回一个 <strong>数组</strong>。例如：$row['name']</p>
 
+
 
+
 
+<h2>标准插入(insert)</h2>
 
+
 
+<code>
 
+$sql = "INSERT INTO mytable (title, name) <br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;VALUES (".$this->db->escape($title).", ".$this->db->escape($name).")";<br />
 
+<br />
 
+$this->db->query($sql);<br />
 
+<br />
 
+echo $this->db->affected_rows();
 
+</code>
 
+
 
+
 
+
 
+
 
+<h2>快捷查询</h2>
 
+
 
+<p><a href="active_record.html">快捷查询类</a>能为我们提供快速取得数据的途径:</p>
 
+
 
+<code>
 
+$query = $this->db->get('table_name');<br />

+<h1>字段数据</h1>
 
+
 
+<h2>$this-&gt;db-&gt;list_fields()</h2>
 
+<p>Returns an array containing the field names. This query can be called two ways:</p>
 
+<br>返回一个包含字段名称的数组。这个查询可以用两种方法调用：
 
+<br/><p>
 
+1.您可以将表名称提供给<dfn>$this-&gt;db-&gt;list_fields()</dfn>调用。
 
+
 
+<code>
 
+$fields = $this-&gt;db-&gt;list_fields('table_name');<br /><br />
 
+
 
+foreach ($fields as $field)<br />
 
+&#123;<br />
 
+&nbsp;&nbsp;&nbsp;echo $field;<br />
 
+&#125;
 
+</code>
 
+<br/>
 
+2.您可以将组合查询语句传递给query函数执行并返回：
 
+
 
+<code>
 
+$query = $this-&gt;db-&gt;query('SELECT * FROM some_table');
 
+<br /><br />
 
+
 
+foreach ($query-&gt;list_fields() as $field)<br />
 
+&#123;<br />
 
+&nbsp;&nbsp;&nbsp;echo $field;<br />
 
+&#125;
 
+</code>
 
+
 
+
 
+<h2>$this-&gt;db-&gt;field_exists()</h2>
 
+
 
+<p>Sometimes it's helpful to know whether a particular field exists before performing an action.
 
+Returns a boolean TRUE/FALSE.  Usage example:</p>
 
+<br/>
 
+在执行一个动作前就先确认某个特殊字段是否存在在某些时候非常有用。返回一个布尔值：TRUE/FALSE。实例：
 
+<code>
 
+if ($this-&gt;db-&gt;field_exists('field_name', 'table_name'))<br />
 
+&#123;<br />
 
+&nbsp;&nbsp; // some code...<br />
 
+&#125;
 
+</code>
 
+
 
+<p>Note:  Replace <em>field_name</em> with the name of the column you are looking for, and replace
 
+
 
+<em>table_name</em> with the name of the table you are looking for.</p>
 
+<br/>
 
+注解：替换<em>field_name</em>为您要查找的字段名称，同时替换<em>table_name</em>为您要查找表名。
 
+
 
+
 
+
 
+<h2>$this-&gt;db-&gt;field_data()</h2>
 
+<p>Returns an array of objects containing field information.</p>
 
+<br/>
 
+返回一个包含字段信息的对象数组。
 
+<p>Sometimes it's helpful to gather the field names or other metadata, like the column type, max length, etc.</p>
 
+<br/>
 
+收集字段的名称或者其它元数据在某些时候非常有用，例如列的数据类型、最大长度等。
 
+
 
+<p class="important">Note: Not all databases provide meta-data.</p>
 
+<br/>注解：并非所有数据库都提供元数据。
 
+
 
+<p>Usage example:</p>
 
+<br/>
 
+例子：
 
+
 
+<code>
 
+$fields = $this-&gt;db-&gt;field_data('table_name');<br /><br />
 
+
 
+foreach ($fields as $field)<br />
 
+&#123;<br />
 
+&nbsp;&nbsp;&nbsp;echo $field-&gt;name;<br />
 
+&nbsp;&nbsp;&nbsp;echo $field-&gt;type;<br />
 
+&nbsp;&nbsp;&nbsp;echo $field-&gt;max_length;<br />
 
+
 
+&nbsp;&nbsp;&nbsp;echo $field-&gt;primary_key;<br />
 
+&#125;
 
+</code>
 
+
 
+<p>If you have run a query already you can use the result object instead of supplying the table name:</p>
 
+<br/>如果您想执行一个已有的查询时你可用返回项替换掉表格名称：
 
+
 
+<code>
 
+$query = $this-&gt;db-&gt;query("YOUR QUERY");<br />
 
+$fields = $query-&gt;field_data();
 
+</code>
 
+
 
+
 
+<p>The following data is available from this function if supported by your database:</p>
 
+<br/>
 
+如果你的数据库支持，以下数据在这个函数中将是可用的：
 
+
 
+<ul>
 
+<li>name - 列名称</li>
 
+<li>max_length - 列的最大长度</li>
 
+<li>primary_key - 1 如果此列被定义为主键</li>
 
+<li>type - 指定列的数据类型</li>
 
+</ul><p>&nbsp;</p>

+</ul>
 
+
 
+
 
+<h2><a name="init"></a>初始化</h2>
 
+
 
+<p class="important"><strong>注意:</strong>&nbsp; 欲初始化数据库维护类，请确保你的数据库驱动已经运行，因为该类依赖于数据库驱动。</p>
 
+
 
+<p>使用如下方法载入数据库维护类:</p>
 
+
 
+<code>$this-&gt;load-&gt;dbforge()</code>
 
+
 
+<p>一旦初始化，就可以使用<dfn>$this-&gt;dbforge</dfn> 对象访问类中函数:</p>
 
+
 
+<code>$this-&gt;dbforge-&gt;some_function()</code>
 
+<h2><a name="create"></a>$this-&gt;dbforge-&gt;create_database('db_name')</h2>
 
+
 
+<p>允许你创建由第一个参数指定的数据库。根据成功或失败，返回 TRUE/FALSE:</p>
 
+
 
+<code>if ($this-&gt;dbforge-&gt;create_database('my_db'))<br />
 
+&#123;<br />
 
+&nbsp;&nbsp;&nbsp; echo '数据库已经被创建!';<br />
 
+&#125;</code>
 
+
 
+
 
+<h2><a name="drop"></a>$this-&gt;dbforge-&gt;drop_database('db_name')</h2>
 
+
 
+<p>允许你删除由第一个参数指定的数据库。根据成功或失败，返回 TRUE/FALSE:</p>
 
+
 
+<code>if ($this-&gt;dbforge-&gt;drop_database('my_db'))<br />
 
+&#123;<br />
 
+&nbsp;&nbsp;&nbsp; echo '数据库已经被删除!';<br />
 
+&#125;</code>
 
+
 
+
 
+<h1>创建和删除表</h1>
 
+<p>创建表时有这么几件事需要你来完成。添加字段，添加主键和修改列。CodeIgniter提供如下方法完成这些操作。</p>
 
+<h2><a name="add_field" id="add_field"></a>添加字段</h2>
 
+<p>字段由关联数组创建。在数组中必须包含与字段数据类型相关的“类型”键。例如，INT,VARCHAR,TEXT等等。许多数据类型（如 VARCHAR）还需要“约束”键。</p>
 
+<p><code>$fields = array(<br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'users' =&gt; array(<br />
 
+    &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'type' =&gt; 'VARCHAR',<br />
 
+    &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'constraint' =&gt; '100',<br />
 
+    &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;),<br />
 
+    &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;);<br />
 
+    <br />
 
+// 当字段被添加后，将被翻译为 &quot;users VARCHAR(100)&quot; .</code></p>
 
+<p>此外，还可以使用下列键/值:</p>
 
+<ul>
 
+    <li>unsigned/true:&nbsp;在字段定义中生成“UNSIGNED”。</li>
 
+    <li>default/value:&nbsp;在字段定义中生成一个缺省值。</li>
 
+    <li>null/true:&nbsp;在字段定义中生成“NULL” 。没有这个，字段缺省为“NOT NULL”。</li>
 
+    <li>auto_increment/true:&nbsp;为字段生成自动增量标记。注意，字段类型必须支持自动增量标记，如整型。</li>
 
+    </ul>
 
+<p><code>$fields = array(<br />
 
+    &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'blog_id' =&gt; array(<br />
 
+    &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'type' =&gt; 'INT',<br />

+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'type' =&gt;'VARCHAR',<br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'constraint' =&gt; '100',<br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'default' =&gt; 'King of Town',<br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;),<br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'blog_description' =&gt; array(<br />

+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'null' =&gt; TRUE,<br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;),<br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;);<br />
 
+</code></p>
 
+<p>字段定义后，使用<dfn>$this-&gt;dbforge-&gt;add_field($fields);</dfn> 添加字段。接下来调用 <dfn>create_table()</dfn> 函数创建表。</p>
 
+<h3>$this-&gt;dbforge-&gt;add_field()</h3>
 
+<p>添加字段函数将接受上面这个数组。</p>
 
+<h3>传递字符串作为字段定义</h3>
 
+<p>如果你确切地知道自己要如何创建一个字段，你可以将字符串作为字段定义传递给 add_field():</p>
 
+<p><code>$this-&gt;dbforge-&gt;add_field(&quot;label varchar(100) NOT NULL DEFAULT 'default label'&quot;);</code></p>
 
+<p class="important">说明: 多次调用 <dfn>add_field()</dfn> 是累加性的。</p>
 
+<h3>创建一个 id 字段</h3>
 
+<p>创建id字段有一种特殊的例外情况。一个id类型的字段将会被自动地赋值为 INT(9) 类型的自动递增主键。</p>
 
+<p><code>$this-&gt;dbforge-&gt;add_field('id');<br />
 
+    // 生成 id INT(9) NOT NULL AUTO_INCREMENT</code></p>
 
+<h2><a name="add_key" id="add_key"></a>添加键</h2>
 
+<p>一般来说，你会需要表中有键。这是通过 <dfn>$this-&gt;dbforge-&gt;add_key('field')</dfn> 来实现的。可选的第二个参数如果被设置为TRUE，那么就会生成一个主键。请注意 <dfn>add_key()</dfn> 后面必须调用 <dfn>create_table()</dfn>。</p>
 
+<p>多列的非主键必须通过数组来传递。下面的示例输出是用于 MySQL 的。</p>
 
+<p><code>$this-&gt;dbforge-&gt;add_key('blog_id', TRUE);<br />
 
+    // 生成 PRIMARY KEY `blog_id` (`blog_id`)<br />
 
+    <br />
 
+    $this-&gt;dbforge-&gt;add_key('blog_id', TRUE);<br />
 
+    $this-&gt;dbforge-&gt;add_key('site_id', TRUE);<br />
 
+    // 生成 PRIMARY KEY `blog_id_site_id` (`blog_id`, `site_id`)<br />
 
+    <br />
 
+    $this-&gt;dbforge-&gt;add_key('blog_name');<br />

+    <br />
 
+    $this-&gt;dbforge-&gt;add_key(array('blog_name', 'blog_label'));<br />
 
+    // 生成 KEY `blog_name_blog_label` (`blog_name`, `blog_label`)</code></p>
 
+<p class="important">译者注：此处存在BUG!经验证，以上代码创建的是两个单独的非主键，而不是一个多列的非主键。有关此BUG的解决方案，详见<a href="#" title='有关BUG的一个可行的解决方案'>CI中国论坛！</a></p>
 
+<h2><a name="create_table" id="create_table"></a>创建表</h2>
 
+<p>声明了字段和键之后，你就可以使用下面的方法来创建一个表:</p>
 
+<p><code>$this-&gt;dbforge-&gt;create_table('table_name');<br />
 
+// 生成 CREATE TABLE table_name</code></p>
 
+<p>可选的第二个参数如果被设置为TRUE，那么，表的定义中就会添加 &quot;IF NOT EXISTS&quot; 子句</p>
 
+<p><code>$this-&gt;dbforge-&gt;create_table('table_name', TRUE);<br />
 
+// 生成 CREATE TABLE IF NOT EXISTS table_name</code></p>
 
+<h2><a name="drop_table" id="drop_table"></a>删除表</h2>
 
+<p>执行一条 DROP TABLE 语句</p>
 
+<p><code>$this-&gt;dbforge-&gt;drop_table('table_name');<br />
 
+ // 生成 DROP TABLE IF EXISTS  table_name</code></p>
 
+<h2><a name="rename_table" id="rename_table"></a>重命名表</h2>
 
+<p>执行一次表重命名</p>
 
+<p><code>$this-&gt;dbforge-&gt;rename_table('old_table_name', 'new_table_name');<br />
 
+ // 生成 ALTER TABLE old_table_name RENAME TO new_table_name</code></p>
 
+<h1><a name="modifying_tables" id="modifying_tables"></a>修改表</h1>
 
+<h2>$this-&gt;dbforge-&gt;add_column()</h2>
 
+<p>这里的 add_column() 函数用来修改已经存在的表，并添加一个或多个字段。 它接受与上面相同的数组参数，并可用于无限数量的附加字段。</p>
 
+<p><code>$fields = array(<br />
 
+    &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'preferences' =&gt; array('type' =&gt; 'TEXT')<br />
 
+);<br />
 
+$this-&gt;dbforge-&gt;add_column('table_name', $fields);<br />
 
+<br />
 
+// 生成 ALTER TABLE table_name ADD    preferences TEXT</code></p>
 
+<h2>$this-&gt;dbforge-&gt;drop_column()</h2>
 
+<p>用于从表中移除一个列。 </p>
 
+<p><code>$this-&gt;dbforge-&gt;drop_column('table_name', 'column_to_drop');</code></p>
 
+<h2>$this-&gt;dbforge-&gt;modify_column()</h2>
 
+<p>本函数的用法与 add_column() 几乎完全相同，唯一的区别在于，本函数的用途是修改一个已存在的列，而不是添加一个新的。要重命名的话，你可以在字段定义数组中添加一个 &quot;name&quot; 键。</p>
 
+<p><code>$fields = array(<br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'old_name' =&gt; array(<br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'name' =&gt; 'new_name',<br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'type' =&gt; 'TEXT',<br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;),<br />
 
+);<br />
 
+$this-&gt;dbforge-&gt;modify_column('table_name', $fields);<br />
 
+    <br />
 
+    // 生成 ALTER TABLE table_name CHANGE    old_name new_name TEXT </code></p>

+<h1>查询辅助函数</h1>
 
+
 
+<h2>$this-&gt;db-&gt;insert_id()</h2>
 
+<br/>
 
+这个ID号是执行数据插入时的ID。
 
+
 
+<h2>$this-&gt;db-&gt;affected_rows()</h2>
 
+<p>Displays the number of affected rows, when doing "write\" type queries (insert, update, etc.).</p>
 
+<br/>
 
+当执行写入操作（insert,update等）的查询后，显示被影响的行数。<br/>
 
+<p>Note:  In MySQL "DELETE FROM TABLE" returns 0 affected rows. The database class has a small hack that allows it to return the
 
+correct number of affected rows.  By default this hack is enabled but it can be turned off in the database driver file.</p>
 
+<br/>
 
+注意：在 MySQL 中“DELETE FROM TABLE”的被影响行数将会返回 0。database 类有一个小 hack 允许返回正确的被影响的行数。默认情况下这个 hack 功能是打开的但可以在数据库驱动文件中关闭它。
 
+
 
+<h2>$this-&gt;db-&gt;count_all();</h2>
 
+<p>Permits you to determine the number of rows in a particular table.  Submit the table name in the first parameter. Example:</p>
 
+<br/>
 
+计算出指定表的总行数并返回。在第一个参数中写入被提交的表名。例如：
 
+<code>echo $this-&gt;db-&gt;count_all('<var>my_table</var>');<br />
 
+
 
+<br />
 
+// Produces an integer, like 25
 
+</code>
 
+
 
+
 
+<h2>$this-&gt;db-&gt;platform()</h2>
 
+<p>Outputs the database platform you are running (MySQL, MS SQL, Postgres, etc...):</p>
 
+<p>输出系统使用的数据库平台(MySQL, MS SQL, Postgres……)</p>
 
+<code>echo $this-&gt;db-&gt;platform();</code>
 
+
 
+
 
+<h2>$this-&gt;db-&gt;version()</h2>
 
+<p>Outputs the database version you are running:</p><br/>
 
+输出系统正在运行的数据库版本号
 
+
 
+<code>echo $this-&gt;db-&gt;version();</code>
 
+
 
+
 
+<h2>$this-&gt;db-&gt;last_query();</h2>
 
+<p>Returns the last query that was run (the query string, not the result).  Example:</p>
 
+<p>返回最后运行的查询（是查询语句，不是查询结果）</p>
 
+
 
+<code>$str = $this-&gt;db-&gt;last_query();<br />
 
+<br />
 
+// Produces:  SELECT * FROM sometable....
 
+</code>
 
+
 
+
 
+<p>The following two functions help simplify the process of writing database INSERTs and UPDATEs.</p>
 
+<br/>
 
+下面的两个函数简化了写入数据库的insert和update操作。
 
+
 
+
 
+<h2>$this-&gt;db-&gt;insert_string(); </h2>
 
+<p>This function simplifies the process of writing database inserts. It returns a correctly formatted SQL insert string. Example:</p>
 
+<br/>
 
+这个函数简化了写入数据库的insert函数。它返回一个标准的SQL insert字符串。例如：
 
+
 
+<code>$data = array('name' => $name, 'email' => $email, 'url' => $url);<br />
 
+<br />
 
+$str = $this-&gt;db-&gt;insert_string('table_name', $data);
 
+</code>
 
+
 
+<p>The first parameter is the table name, the second is an associative array with the data to be inserted.  The above example produces:</p>
 
+<br/>
 
+第一个参数是表名，第二个是被插入数据的联合数组，上面的例子生成的效果为：
 
+<code>INSERT INTO table_name (name, email, url) VALUES ('Rick', 'rick@example.com', 'example.com')</code>
 
+
 
+<p class="important">Note: Values are automatically escaped, producing safer queries.</p>
 
+<br/>
 
+注解：被插入的数据会被自动转换和过滤，生成安全的查询语句。
 
+
 
+
 
+
 
+<h2>$this-&gt;db-&gt;update_string(); </h2>
 
+<p>This function simplifies the process of writing database updates. It returns a correctly formatted SQL update string. Example:</p>
 
+<br/>
 
+这个函数简化了写入数据库的update操作。它返回一条格式正确的SQL update字符串。例如：
 
+
 
+<code>$data = array('name' => $name, 'email' => $email, 'url' => $url);<br />
 
+<br />
 
+$where = "author_id = 1 AND status = 'active'";
 
+<br /><br />
 
+$str = $this-&gt;db-&gt;update_string('table_name', $data, $where);
 
+
 
+</code>
 
+
 
+<p>The first parameter is the table name, the second is an associative array with the data to be updated, and the third parameter is the "where" clause. The above example produces:</p>
 
+<br />
 
+第一个参数是表名，第二个是被更新数据的关联数组，第三个参数是“where”子句。上面的例子生成的效果为：
 
+<code> UPDATE table_name SET name = 'Rick', email = 'rick@example.com', url = 'example.com' WHERE author_id = 1 AND status = 'active'</code>
 
+
 
+<p class="important">Note: Values are automatically escaped, producing safer queries.</p>
 
+<br/>
 
+注解：被插入的数据会被自动转换和过滤，生成安全的查询语句。<p>&nbsp;</p>

+<h1>查询</h1>
 
+
 
+<h2>$this-&gt;db-&gt;query();</h2>
 
+
 
+<p>要提交一个查询，用以下函数：</p>
 
+
 
+<code>$this-&gt;db-&gt;query('YOUR QUERY HERE');</code>
 
+
 
+<p><dfn>query()</dfn> 函数以<strong>object(对象)</strong>的形式返回一个数据库结果集. 当使用 "read" 模式来运行查询时, 你可以使用“<a href="results.html">显示你的结果集</a>”来显示查询结果; 当使用 "write" 模式来运行查询时, 将会仅根据执行的成功或失败来返回 TRUE 或 FALSE. 当你需要将返回的结果赋值给一个自定义变量的时候, 你可以这样操作:</p>
 
+
 
+<code><var>$query</var> = $this-&gt;db-&gt;query('YOUR QUERY HERE');</code>
 
+
 
+<h2>$this-&gt;db-&gt;simple_query();</h2>
 
+
 
+<p>这是一个简化版本的 <dfn>$this-&gt;db-&gt;query()</dfn> 函数.  它仅返回 True(bool) 和 False(bool) 以表示查询成功与失败.
 
+它将不会返回查询数据集，无法设置查询计时器(设置环境变量)，无法编译绑定数据，不能够存储查询诊断信息。
 
+简单地说，他是一个用于提交查询的函数，对于大多数用户而言并不会使用到它。</p>
 
+
 
+<h1>Working with Database prefixes manually</h1>
 
+<p>If you have configured a database prefix and would like to prepend it to a table name for use in a native SQL query for example, then you can use the following:</p>
 
+<p><code>$this-&gt;db-&gt;dbprefix('tablename');<br />
 
+// outputs prefix_tablename</code></p>
 
+
 
+<p>If for any reason you would like to change the prefix programatically without needing to create a new connection, you can use this method:</p>
 
+<p><code>$this-&gt;db-&gt;set_dbprefix('newprefix');<br /><br />
 
+$this-&gt;db-&gt;dbprefix('tablename');<br />
 
+// outputs newprefix_tablename</code></p>
 
+
 
+<h1>保护标识符</h1>
 
+<p>在许多数据库中，保护表(table)和字段(field)的名称是明智的，例如在MySQL中使用反引号。<strong>Active Record的查询都已被自动保护</strong>，然而，如果您需要手动保护一个标识符，您也可以这样：</p>
 
+<p><code>$this-&gt;db-&gt;protect_identifiers('table_name');</code></p>
 
+
 
+<p class="important">Although Active Record will try its best to properly quote any field and table names that you feed it, note that it is NOT designed to work with arbitrary user input. DO NOT feed it with unsanitized user data.</p>
 
+
 
+<p>这个函数也会给你的表名添加一个前缀，它假定在你的数据库配置文件中已指定了一个前缀。可通过将第二个参数设置为<kbd>TRUE</kbd> (boolen) 启用前缀:</p>
 
+<p><code>$this-&gt;db-&gt;protect_identifiers('table_name', <kbd>TRUE</kbd>);</code></p>
 
+
 
+<h1>转义查询</h1>
 
+
 
+<p>将数据转义以后提交到你的数据库是非常好的安全做法，CodeIgniter 提供了 3 个函数帮助你完成这个工作。</p>
 
+
 
+<ol>
 
+
 
+<li><strong>$this-&gt;db-&gt;escape()</strong> 这个函数将会确定数据类型，以便仅对字符串类型数据进行转义。并且，它也会自动把数据用单引号括起来，所以你不必手动添加单引号，用法如下：
 
+
 
+<code>$sql = "INSERT INTO table (title) VALUES(".$this-&gt;db-&gt;escape($title).")";</code></li>
 
+
 
+
 
+<li><strong>$this-&gt;db-&gt;escape_str()</strong>  此函数将忽略数据类型对传入数据进行转义。更多时候你将使用上面的函数而不是这个。这个函数的使用方法是：
 
+
 
+<code>$sql = "INSERT INTO table (title) VALUES('".$this-&gt;db-&gt;escape_str($title)."')";</code></li>
 
+
 
+<li><strong>$this-&gt;db-&gt;escape_like_str()</strong>  This method should be used when strings are to be used in LIKE conditions so that LIKE wildcards ('%', '_') in the string are also properly escaped.
 
+
 
+<code>$search = '20% raise';<br />
 
+  $sql = "SELECT id FROM table WHERE column LIKE '%".$this-&gt;db-&gt;escape_like_str($search)."%'";</code></li>
 
+
 
+</ol>
 
+
 
+
 
+<h1>封装查询</h1>
 
+
 
+
 
+<p>封装，通过让系统为你组装各个查询语句，能够简化你的查询语法。参加下面的范例：</p>
 
+
 
+<code>
 
+$sql = "SELECT * FROM some_table WHERE id = <var>?</var> AND status = <var>?</var> AND author = <var>?</var>";
 
+
 
+<br /><br />
 
+$this-&gt;db-&gt;query($sql, array(3, 'live', 'Rick'));
 
+</code>
 
+
 
+<p>查询语句中的问号会自动被查询函数中位于第二个参数位置的数组中的值所替代。</p>
 
+<p class="important">使用封装查询的第二个好处是所有的值都会被自动转义，形成了较为安全的查询语句。你无需手动地去转义这些数据；控制器将会自动为你进行。</p><p>&nbsp;</p>

+<h1>生成查询记录集</h1>
 
+
 
+
 
+<p>支持使用以下方法生成记录集</p>
 
+
 
+ <h2>result()</h2>
 
+ 
+ <p>该方法执行成功返回一个<strong>对象数组</strong>，失败则返回一个<strong>空数组</strong>。
 
+ 
+ 一般情况下，我们使用下面的方法遍历结果，代码就像这样：</p>
 
+ 
+ <code>
 
+ $query = $this-&gt;db-&gt;query("要执行的 SQL");<br />
 
+ <br />
 
+
 
+ foreach ($query-&gt;result() as $row)<br />
 
+ &#123;<br />
 
+ &nbsp;&nbsp;&nbsp;echo $row-&gt;title;<br />
 
+ &nbsp;&nbsp;&nbsp;echo $row-&gt;name;<br />
 
+ &nbsp;&nbsp;&nbsp;echo $row-&gt;body;<br />
 
+ &#125;</code>
 
+ 
+ <p>本函数的别名是 <dfn>result_object()</dfn>。</p>
 
+
 
+ <p>如果当前所执行的 SQL 可能<strong>不会</strong>返回记录集，我们可以使用如下方法进行判断：</p>
 
+ 
+ <code>
 
+
 
+ $query = $this-&gt;db-&gt;query("要执行的 SQL");<br />
 
+ <br />
 
+ if ($query-&gt;num_rows() > 0)<br />
 
+ &#123;<br />
 
+ &nbsp;&nbsp;&nbsp;foreach ($query-&gt;result() as $row)<br />
 
+ &nbsp;&nbsp;&nbsp;&#123;<br />
 
+
 
+ &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;echo $row-&gt;title;<br />
 
+ &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;echo $row-&gt;name;<br />
 
+ &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;echo $row-&gt;body;<br />
 
+ &nbsp;&nbsp;&nbsp;&#125;<br />
 
+ &#125;
 
+ </code>
 
+
 
+ <p>你可以传递一个字符串给result()函数，该字符串代表着某个类为每一个result对象进行实例化 （注意：该类必须已经被加载）。</p>
 
+
 
+ <code>
 
+ $query = $this-&gt;db-&gt;query("SELECT * FROM users;");<br />
 
+ <br />
 
+ foreach ($query-&gt;result('User') as $row)<br />
 
+ &#123;<br />
 
+ &nbsp;&nbsp;&nbsp;echo $row-&gt;name; // call attributes<br />
 
+ &nbsp;&nbsp;&nbsp;echo $row-&gt;reverse_name(); // or methods defined on the 'User' class<br />
 
+ &#125;
 
+ </code>
 
+
 
+
 
+ <h2>result_array()</h2>
 
+
 
+ <p>该方法执行成功时将记录集作为<strong>关联数组</strong>返回。失败时返回<strong>空数组</strong>。一般情况下，我们使用下面的方法遍历结果，代码就像这样：</p>
 
+ <code>
 
+ $query = $this-&gt;db-&gt;query("要执行的 SQL");<br />
 
+ <br />
 
+ foreach ($query-&gt;result_array() as $row)<br />
 
+ &#123;<br />
 
+ &nbsp;&nbsp;&nbsp;echo $row['title'];<br />
 
+
 
+ &nbsp;&nbsp;&nbsp;echo $row['name'];<br />
 
+ &nbsp;&nbsp;&nbsp;echo $row['body'];<br />
 
+ &#125;</code>
 
+
 
+
 
+ <h2>row()</h2>
 
+ 
+ <p>该函数将当前请求的第一行数据作为 <strong>object</strong> 返回。这里是示例代码：</p>
 
+
 
+ <code>
 
+ $query = $this-&gt;db-&gt;query("要执行的 SQL");<br />
 
+ <br />
 
+ if ($query-&gt;num_rows() > 0)<br />
 
+ &#123;<br />
 
+ &nbsp;&nbsp;&nbsp;$row = $query-&gt;row();
 
+ <br /><br />
 
+ &nbsp;&nbsp;&nbsp;echo $row-&gt;title;<br />
 
+
 
+ &nbsp;&nbsp;&nbsp;echo $row-&gt;name;<br />
 
+ &nbsp;&nbsp;&nbsp;echo $row-&gt;body;<br />
 
+ &#125;
 
+ </code>
 
+ 
+ <p>你可以传递参数(参数是行的索引)以便获得某一行的数据。比如我们要获得第 <dfn>5</dfn> 行的数据：</p>
 
+ 
+ <code>$row = $query-&gt;row(<dfn>4</dfn>);</code>
 
+<p>如果传入的参数超出行索引，则返回第一行(索引为0)数据</p>
 
+
 
+ <p>你也可以添加一个字符串参数，它是一个类在row()函数下实例化的名字：</p>
 
+
 
+ <code>
 
+ $query = $this-&gt;db-&gt;query("SELECT * FROM users LIMIT 1;");<br />
 
+ <br />
 
+ $query-&gt;row(0, 'User')<br />
 
+ echo $row-&gt;name; // call attributes<br />
 
+ echo $row-&gt;reverse_name(); // or methods defined on the 'User' class<br />
 
+ </code>
 
+
 
+ <h2>row_array()</h2>
 
+
 
+ <p>功能与 <var>row()</var> 一样, 区别在于该函数返回的是一个数组：</p>
 
+
 
+ <code>
 
+ $query = $this-&gt;db-&gt;query("要执行的 SQL");<br />
 
+
 
+ <br />
 
+ if ($query-&gt;num_rows() > 0)<br />
 
+ &#123;<br />
 
+ &nbsp;&nbsp;&nbsp;$row = $query-&gt;row_array();
 
+ <br /><br />
 
+ &nbsp;&nbsp;&nbsp;echo $row['title'];<br />
 
+ &nbsp;&nbsp;&nbsp;echo $row['name'];<br />
 
+
 
+ &nbsp;&nbsp;&nbsp;echo $row['body'];<br />
 
+ &#125;
 
+ </code>
 
+
 
+ 
+ <p>你可以传递参数(参数是行的索引)以便获得某一行的数据。比如我们要获得第 <dfn>5</dfn> 行的数据：</p>
 
+ 
+ <code>$row = $query-&gt;row_array(<dfn>4</dfn>);</code>
 
+
 
+ <p>如果传入的参数超出行索引，则返回第一行(索引为0)数据</P>
 
+
 
+  <p>除此以外, 我们还可以使用下面的方法通过游标的方式获取记录：</p>
 
+
 
+<p>
 
+ <strong>$row = $query-&gt;first_row()</strong><br />
 
+ <strong>$row = $query-&gt;last_row()</strong><br />
 
+ <strong>$row = $query-&gt;next_row()</strong><br />
 
+ <strong>$row = $query-&gt;previous_row()</strong>
 
+</p>
 
+
 
+<p>默认情况下他们将返回一个 <strong>object</strong>，同时你也可以传递参数 "array" 以便使用 <strong>array</strong> 的方式获取数据</p>
 
+
 
+<p>
 
+ <strong>$row = $query-&gt;first_row('array')</strong><br />
 
+ <strong>$row = $query-&gt;last_row('array')</strong><br />
 
+ <strong>$row = $query-&gt;next_row('array')</strong><br />
 
+ <strong>$row = $query-&gt;previous_row('array')</strong>
 
+</p>
 
+
 
+
 
+<h1>结果集辅助函数</h1>
 
+
 
+
 
+<h2>$query-&gt;num_rows()</h2>
 
+<p>该函数将会返回当前请求的行数。在本例子中, <dfn>$query</dfn> 表示当前 SQL 所产生的请求结果对象：</p>
 
+
 
+<code>$query = $this-&gt;db-&gt;query('SELECT * FROM my_table');<br /><br />
 
+echo $query-&gt;num_rows();
 
+</code>
 
+
 
+<h2>$query-&gt;num_fields()</h2>
 
+<p>该函数返回当前请求的字段数（列数）：</p>
 
+
 
+<code>$query = $this-&gt;db-&gt;query('SELECT * FROM my_table');<br /><br />
 
+echo $query-&gt;num_fields();
 
+</code>
 
+
 
+
 
+
 
+<h2>$query-&gt;free_result()</h2>
 
+<p>该函数将会释放当前查询所占用的内存并删除其关联的资源标识。通常来说，PHP 将会脚本执行结束后自动释放内存。如果当前执行的请求将要花很长时间并且占用比较大的资源时,该函数可以在一定程度上降低资源的消耗：
 
+</p>
 
+
 
+<code>$query = $this-&gt;db-&gt;query('SELECT title FROM my_table');<br /><br />
 
+foreach ($query-&gt;result() as $row)<br />
 
+&#123;<br />
 
+&nbsp;&nbsp;&nbsp;echo $row-&gt;title;<br />
 
+&#125;<br />
 
+$query-&gt;free_result();  // $query 将不再可用<br />
 
+<br />
 
+$query2 = $this-&gt;db-&gt;query('SELECT name FROM some_table');<br /><br />
 
+$row = $query2-&gt;row();<br />
 
+
 
+echo $row-&gt;name;<br />
 
+$query2-&gt;free_result();  // $query2 将不再可用
 
+</code><p>&nbsp;</p>

+<h1>事务</h1>
 
+
 
+<p>CodeIgniter的数据库抽象允许你在支持事务安全的数据库表中使用<dfn>事务</dfn>。在MySQL中，你需要用InnoDB或BDB表而不是更常用的MyISAM。大多数其它的数据库平台都原生支持事务。</p>
 
+
 
+<p>如果你对事务不熟悉，我们建议您上网寻找相关资源学习。以下信息假设你已经明白事务的相关概念。</p>
 
+
 
+<h2>CodeIgniter 的事务方法</h2>
 
+
 
+<p>CodeIgniter 使用的事务方法与流行的数据库类ADODB所使用的处理过程非常相似。我们选择那种方法是因为它极大地简化了运行事务的处理过程。大多数情况下你只需要编写两行代码就行了。</p>
 
+
 
+<p>传统上, 事务需要实现大量工作, 他们要求你随时跟踪你的查询, 并根据查询的成功或失败来决定 <dfn>提交</dfn> 还是 <dfn>回滚</dfn>。这是特别麻烦的嵌套查询。相比之下, 我们实现了一种智能的事务系统, 它将自动地为你做这些事情(如果你选择手动管理你的事务, 这也是可以的, 但这确实没什么好处)。</p>
 
+
 
+<h2>运行事务</h2>
 
+
 
+<p>要使用事务来运行你的查询, 你可以使用如下所述的 <dfn>$this-&gt;db-&gt;trans_start()</dfn> 和 <dfn>$this-&gt;db-&gt;trans_complete()</dfn> 函数:</p>
 
+
 
+<code>
 
+<kbd>$this-&gt;db-&gt;trans_start();</kbd><br />
 
+$this-&gt;db-&gt;query('一条SQL查询...');<br />
 
+
 
+$this-&gt;db-&gt;query('另一条查询...');<br />
 
+$this-&gt;db-&gt;query('还有一条查询...');<br />
 
+<kbd>$this-&gt;db-&gt;trans_complete();</kbd>
 
+</code>
 
+
 
+<p>在 start/complete 函数之间, 你想运行多少条查询都可以, 根据任何给定查询的成功或失败, 它们将被提交或者回滚。</p>
 
+
 
+<h2>严格模式(Strict Mode)</h2>
 
+
 
+<p>默认情况下, CodeIgniter 以<dfn>严格模式</dfn>运行所有事务。当严格模式被启用时, 如果你正在运行多组的事务, 只要有一组失败, 所有组都会被回滚。如果严格模式被禁用, 每一组都被视为独立的组, 这意味着其中一个组的失败不会影响其它组。</p>
 
+
 
+<p>严格模式能以下面的方式禁用:</p>
 
+
 
+<code>$this-&gt;db-&gt;trans_strict(FALSE);</code>
 
+
 
+
 
+<h2>管理错误信息</h2>
 
+
 
+<p>如果你在你的 <dfn>config/database.php</dfn> 文件中启用了错误报告, 当提交没有成功时, 你会看到一条标准的错误信息。如果调试被关闭, 你可以通过这种方式来管理你的错误信息:</p>
 
+
 
+<code>
 
+$this-&gt;db-&gt;trans_start();<br />
 
+$this-&gt;db-&gt;query('AN SQL QUERY...');<br />
 
+$this-&gt;db-&gt;query('ANOTHER QUERY...');<br />
 
+$this-&gt;db-&gt;trans_complete();<br />
 
+<br />
 
+if (<kbd>$this-&gt;db-&gt;trans_status()</kbd> === FALSE)<br />
 
+&#123;<br />
 
+
 
+&nbsp;&nbsp;&nbsp;&nbsp;// 生成一条错误信息... 或者使用 log_message() 函数来记录你的错误信息<br />
 
+&#125;
 
+</code>
 
+
 
+
 
+<h2>禁用事务</h2>
 
+
 
+<p>当你使用 <dfn>$this-&gt;db-&gt;trans_start()</dfn> 时, 事务就已经被自动启用了。如果你想要禁用事务, 你可以使用 <dfn>$this-&gt;db-&gt;trans_off()</dfn> 来实现:</p>
 
+
 
+<code>
 
+
 
+<kbd>$this-&gt;db-&gt;trans_off()</kbd><br /><br />
 
+
 
+$this-&gt;db-&gt;trans_start();<br />
 
+$this-&gt;db-&gt;query('AN SQL QUERY...');<br />
 
+$this-&gt;db-&gt;trans_complete();
 
+</code>
 
+
 
+<p class="important">当事务被禁用的时候, 你的查询将被自动提交, 就像没有使用事务时那样。</p>
 
+
 
+
 
+<h2>测试模式(Test Mode)</h2>
 
+
 
+<p>你可以选择性地将事务系统设置到 "测试模式" ,  这将导致你的查询被回滚 -- 尽管查询会生成有效结果。要使用测试模式, 只需将 <dfn>$this-&gt;db-&gt;trans_start()</dfn> 函数的第一个参数设置为 <samp>TRUE</samp> 即可:</p>
 
+
 
+<code>
 
+$this-&gt;db-&gt;trans_start(<samp>TRUE</samp>); // 查询将被回滚<br />
 
+$this-&gt;db-&gt;query('AN SQL QUERY...');<br />
 
+$this-&gt;db-&gt;trans_complete();
 
+</code>
 
+
 
+
 
+<h2>手动运行事务</h2>
 
+
 
+<p>如果你想要手动运行事务, 可以使用下面的方法:</p>
 
+
 
+<code>
 
+$this-&gt;db-&gt;trans_begin();<br /><br />
 
+
 
+$this-&gt;db-&gt;query('AN SQL QUERY...');<br />
 
+$this-&gt;db-&gt;query('ANOTHER QUERY...');<br />
 
+$this-&gt;db-&gt;query('AND YET ANOTHER QUERY...');<br />
 
+
 
+<br />
 
+
 
+if ($this-&gt;db-&gt;trans_status() === FALSE)<br />
 
+&#123;<br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;$this-&gt;db-&gt;trans_rollback();<br />
 
+&#125;<br />
 
+else<br />
 
+&#123;<br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;$this-&gt;db-&gt;trans_commit();<br />
 
+
 
+&#125;<br />
 
+</code>
 
+
 
+<p class="important"><strong>说明:</strong> 手动运行事务时, 请务必使用 <kbd>$this-&gt;db-&gt;trans_begin()</kbd> 函数,  而<strong>不是</strong>
 
+<dfn>$this-&gt;db-&gt;trans_start()</dfn>.</p><p>&nbsp;</p>

+<code>$this-&gt;dbutil-&gt;some_function()</code>
 
+
 
+<h2><a name="list"></a>$this-&gt;dbutil-&gt;list_databases()</h2>
 
+<p>返回一个含有数据库名的数组:</p>
 
+
 
+<code>
 
+$dbs = $this-&gt;dbutil-&gt;list_databases();<br />
 
+<br />
 
+foreach ($dbs as $db)<br />
 
+&#123;<br />
 
+&nbsp;&nbsp;&nbsp; echo $db;<br />
 
+&#125;</code>
 
+
 
+<h2><a name="exists"></a>$this-&gt;dbutil-&gt;database_exists();</h2>
 
+
 
+<p>有时候判断一个特定的数据库是否存在，是非常有用的功能。返回一个布尔值 TRUE/FALSE.  使用范例:</p>
 
+
 
+<code>
 
+if ($this-&gt;dbutil-&gt;database_exists('database_name'))<br />
 
+&#123;<br />
 
+&nbsp;&nbsp; // some code...<br />
 
+&#125;
 
+</code>
 
+
 
+<p>注意:  将 <em>database_name</em> 替换为你想要查找的数据库名称。这个函数是区分大小写的。</p>
 
+
 
+<h2><a name="opttb"></a>$this-&gt;dbutil-&gt;optimize_table('table_name');</h2>
 
+
 
+<p class="important"><strong>注意：</strong>&nbsp; 此特性仅在MySQL/MySQLi数据库中可用。</p>
 
+
 
+
 
+<p>允许你优化第一个参数为表名的表。基于操作的成功或失败返回TRUE或FALSE：</p>
 
+
 
+<code>
 
+if ($this-&gt;dbutil-&gt;optimize_table('table_name'))<br />
 
+&#123;<br />
 
+&nbsp;&nbsp;&nbsp; echo 'Success!';<br />
 
+&#125;
 
+</code>
 
+
 
+<p><strong>注意：</strong> 并非所有数据库平台都支持表优化</p>
 
+
 
+
 
+<h2><a name="repair"></a>$this-&gt;dbutil-&gt;repair_table('table_name');</h2>
 
+
 
+<p class="important"><strong>注意：</strong>&nbsp; 此特性仅在MySQL/MySQLi数据库中可用。</p>
 
+
 
+
 
+<p>允许你修复第一个参数为表名的表。基于操作的成功或失败返回TRUE或FALSE：</p>
 
+
 
+<code>
 
+if ($this-&gt;dbutil-&gt;repair_table('table_name'))<br />
 
+&#123;<br />
 
+&nbsp;&nbsp;&nbsp; echo 'Success!';<br />
 
+&#125;
 
+</code>
 
+
 
+<p><strong>注意：</strong> 并非所有数据库平台都支持表修复。</p>
 
+
 
+
 
+<h2><a name="optdb"></a>$this-&gt;dbutil-&gt;optimize_database();</h2>
 
+
 
+<p class="important"><strong>注意：</strong>&nbsp; 此特性仅在MySQL/MySQLi数据库中可用。</p>
 
+
 
+<p>允许你优化当前DB类所连接到的数据库。返回一个包含DB状态信息的数组，失败返回 FALSE。</p>
 
+
 
+<code>
 
+$result = $this-&gt;dbutil-&gt;optimize_database();<br />
 
+<br />
 
+if ($result !== FALSE)<br />

+</code>
 
+
 
+<p><strong>注意：</strong> 并非所有数据平台都支持表优化。</p>
 
+
 
+
 
+<h2><a name="csv"></a>$this-&gt;dbutil-&gt;csv_from_result($db_result)</h2>
 
+
 
+<p>允许你从查询结果集生成一个CSV文件。第一个参数必须为查询结果集对象。例如：</p>
 
+
 
+<code>
 
+$this-&gt;load-&gt;dbutil();<br />
 
+<br />
 
+$query = $this-&gt;db-&gt;query("SELECT * FROM mytable");<br />
 
+<br />
 
+echo $this-&gt;dbutil-&gt;csv_from_result($query);
 
+</code>
 
+
 
+<p>第二和第三个参数允许你设置分隔符和换行符。默认使用tab（跳格）作为分隔符，使用“\n”作为换行符。例如：</p>
 
+
 
+<code>
 
+$delimiter = ",";<br />
 
+$newline = "\r\n";<br />
 
+<br />
 
+echo $this-&gt;dbutil-&gt;csv_from_result($query, $delimiter, $newline);
 
+</code>
 
+
 
+<p><strong>重要：</strong>&nbsp;此函数不会将生成的CSV文件保存到磁盘。它只是简单的创建CSV格式。如果需要将文件保存到磁盘，使用<a href="../helpers/file_helper.html">文件辅助函数</a>。</p>
 
+
 
+
 
+<h2><a name="xml"></a>$this-&gt;dbutil-&gt;xml_from_result($db_result)</h2>
 
+
 
+<p>允许你从结果集中生成一个XML文件。第一个参数是查询结果集对象，第二个参数为可选数组参数，数组包含配置参数。例如：</p>
 
+
 
+<code>
 
+$this-&gt;load-&gt;dbutil();<br />
 
+<br />
 
+$query = $this-&gt;db-&gt;query("SELECT * FROM mytable");<br />
 
+<br />
 
+$config = array (<br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'root'&nbsp;&nbsp;&nbsp; => 'root',<br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'element' => 'element', <br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'newline' => "\n", <br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'tab'&nbsp;&nbsp;&nbsp;&nbsp;=> "\t"<br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;);<br />
 
+<br />
 
+echo $this-&gt;dbutil-&gt;xml_from_result($query, $config);
 
+</code>
 
+
 
+<p><strong>重要：</strong>&nbsp; 此函数不会将生成的XML文件保存到磁盘。它只是简单的创建XML格式。如果需要将文件保存到磁盘，使用<a href="../helpers/file_helper.html">文件辅助函数</a>。</p>
 
+
 
+<h2><a name="backup"></a>$this-&gt;dbutil-&gt;backup()</h2>
 
+
 
+<p>允许你备份整个数据库或者独立的表。备份数据可以压缩为Zip或Gzip格式。</p>
 
+<p class="important"><strong>注意：</strong>&nbsp; 该特性仅在使用MySQL数据库时有效。</p>
 
+
 
+<p>备注：由于PHP执行时间和内存的限制，备份巨大的数据库可能不太容易成功。如果你的数据库非常大，你可能需要直接从命令行执行相关命令；或者如果你没有相应权限，你可能需要服务器管理员为你做这件事。
 
+</p>
 
+
 
+<h3>用法：</h3>
 
+
 
+<code>
 
+<dfn>// 加载数据库工具类</dfn><br />
 
+$this-&gt;load-&gt;dbutil();<br /><br />
 
+
 
+<dfn>// 备份整个数据库并将其赋值给一个变量</dfn><br />
 
+$backup =& $this-&gt;dbutil-&gt;backup();
 
+
 
+<br /><br />
 
+<dfn>// 加载文件辅助函数并将文件写入你的服务器</dfn><br />
 
+$this-&gt;load-&gt;helper('file');<br />
 
+write_file&#40;'/path/to/mybackup.gz', $backup&#41;;
 
+
 
+<br /><br />
 
+<dfn>// 加载下载辅助函数并将文件发送到你的桌面</dfn><br />
 
+$this-&gt;load-&gt;helper('download');<br />
 
+force_download('mybackup.gz', $backup);
 
+</code>
 
+
 
+<h3>设置备份参数</h3>
 
+
 
+<p>将一个包含了各项参数值的数组作为第一个函数参数传递给备份函数，就可以设置数据库备份的参数。例如:</p>
 
+
 
+<code>$prefs = array(<br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'tables'&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;=> array('table1', 'table2'),&nbsp;&nbsp;// 包含了需备份的表名的数组.<br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'ignore'&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;=> array(),&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;// 备份时需要被忽略的表<br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'format'&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;=> 'txt',&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;// gzip, zip, txt<br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'filename'&nbsp;&nbsp;&nbsp;&nbsp;=> 'mybackup.sql',&nbsp;&nbsp;&nbsp;&nbsp;// 文件名 - 如果选择了ZIP压缩,此项就是必需的<br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'add_drop'&nbsp;&nbsp;&nbsp;&nbsp;=> TRUE,&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;// 是否要在备份文件中添加 DROP TABLE 语句<br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'add_insert'&nbsp;&nbsp;=> TRUE,&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;// 是否要在备份文件中添加 INSERT 语句<br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'newline'&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;=> "\n"&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;// 备份文件中的换行符<br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;);<br />
 
+<br />
 
+$this-&gt;dbutil-&gt;backup($prefs);
 
+</code>
 
+

+<h1>缓存适配器</h1>
 
+<p>注：在2.0.3以前有bug，请下载最新版本的CI。</p>
 
+<p>CodeIgniter提供了多种目前业界流行的快速动态缓存组件的封装类。除了基于纯文本的缓存（文件缓存）外，其他缓存组件均需对服务器环境进行正确配置才能使用，否则程序会抛出致命异常(Fatal Exception)错误。</p>

+  <li><a href="#function_reference" title="Function Reference">函数速查</a></li>

+<h3>支持的缓存适配器</h3>
 
+<ul>
 
+  <li><a href="#apc" title="APC Cache">Alternative PHP Cache (APC) 缓存</a></li>
 
+  <li><a href="#file" title="File Caching">纯文本缓存</a></li>

+  <li><a href="#dummy" title="Dummy Caching">虚拟缓存</a></li>
 
+
 
+</ul>
 
+
 
+<h2 id="example_usage">用法举例</h2>
 
+
 
+<p>下面这个例子：首先加载缓存适配器，然后指定 <a href="#apc" title="APC">APC</a> 作为适配器优先使用的缓存实现，同时，我们指定文本缓存作为替代方案。这样，在一些服务器不支持APC的情况下（如国内的虚拟主机），我们可以使用替代方案保证程序正常运行。</p>
 
+
 
+<code>
 
+$this-&gt;load-&gt;driver('cache', array('adapter' => 'apc', 'backup' => 'file'));<br />
 
+<br />
 
+if ( ! $foo = $this-&gt;cache-&gt;get('foo'))<br />
 
+
 
+&#123;<br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;echo 'Saving to the cache!&lt;br />';<br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;$foo = 'foobarbaz!';<br />
 
+<br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;// Save into the cache for 5 minutes<br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;$this-&gt;cache-&gt;save('foo', $foo, 300);<br />
 
+&#125;<br />
 
+<br />
 
+echo $foo;
 
+</code>
 
+
 
+<p><strong>译者注：为了便于理解上面的代码，我们不妨举个例子。缓存适配器，我们可以理解为一个“通电的插座”；而APC缓存，相当于我们希望插在插座上使用的空调；文本缓存我们可以理解与空调功能相同但效率却完全不同的电风扇。</strong></p>
 
+
 
+<h1 id="function_reference">Function Reference</h1>
 
+
 
+<h2>is_supported(<var>driver</var>['string'])</h2>
 
+
 
+<p>如果你通过 <samp>$this-&gt;cache-&gt;get()</samp> 来访问缓存适配器，此函数将自动触发。但是，如果你希望有针对性的使用某个具体的缓存实现（如下例中的 APC），请确保调用此函数，用来检查服务器环境是否支持这种缓存类型。</p>
 
+
 
+<code>
 
+if ($this-&gt;cache-&gt;apc-&gt;is_supported())<br />
 
+
 
+&#123;<br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;if ($data = $this-&gt;cache-&gt;apc-&gt;get('my_cache'))<br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&#123;<br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;// do things.<br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&#125;<br />
 
+&#125;
 
+</code>
 
+
 
+<h2>get(<var>id</var>['string'])</h2>
 
+
 
+<p>此函数将尝试从缓存系统中获取指定的缓存项。如果缓存不存在，或者超过缓存期限，则返回 <samp>FALSE</samp>。</p>
 
+<code>$foo = $this-&gt;cache-&gt;get('my_cached_item');</code>
 
+
 
+<h2>save(<var>id</var>['string'], <var>data</var>['mixed'], <var>ttl</var>['int'])</h2>
 
+
 
+<p>此函数尝试将一个缓存项存储到对应的缓存系统中。如果存储失败，则返回<samp>FALSE</samp>。</p>
 
+<p>第三个参数（可选项）指定了缓存的存活时间，默认为60秒。</p>
 
+<code>$this-&gt;cache-&gt;save('cache_item_id', 'data_to_cache');</code>
 
+
 
+<h2>delete(<var>id</var>['string'])</h2>
 
+
 
+<p>此函数尝试从缓存系统中删除某个指定的缓存项。如果删除失败，则返回<samp>FALSE</samp>。</p>
 
+
 
+<code>$this-&gt;cache-&gt;delete('cache_item_id');</code>
 
+
 
+<h2>clean()</h2>
 
+
 
+<p>此函数用来清空所有缓存。如果清空失败，则返回 <samp>FALSE</samp>.</p>
 
+
 
+<code>$this-&gt;cache-&gt;clean();</code>
 
+
 
+<h2>cache_info()</h2>
 
+
 
+<p>此函数将返回所有缓存信息.</p>
 
+
 
+<code>var_dump($this-&gt;cache-&gt;cache_info());</code>
 
+
 
+<h2>get_metadata(<var>id</var>['string'])</h2>
 
+
 
+<p>此函数将返回缓存系统中指定缓存项的详细信息。</p>
 
+
 
+<code>var_dump($this-&gt;cache-&gt;get_metadata('my_cached_item'));</code>

+<h2 id="apc">Alternative PHP Cache (APC) 缓存</h2>
 
+
 
+<p>以上列举的所有方法可直接访问，不需传递特定的适配器实现给适配器加载器，如下：</p>
 
+<code>$this-&gt;load-&gt;driver('cache');<br />
 
+  $this-&gt;cache-&gt;apc-&gt;save('foo', 'bar', 10);</code>
 
+<p>For more information on APC, please see <a href="#">http://php.net/apc</a></p>
 
+
 
+<h2 id="file">基于文件的缓存</h2>
 
+
 
+<p>不同于从输出类（Output Class）缓存, 基于文件的缓存可以对view页面分块缓存。不过使用时需要小心，应该通过对程序进行评测，以确保由于磁盘I/O增加所导致的性能下降相对于缓存所带来的性能提升是值得的。</p>
 
+
 
+<p>以上列举的所有方法可直接访问，不需传递特定的适配器实现给适配器加载器，如下：</p>
 
+<code>$this-&gt;load-&gt;driver('cache');<br />
 
+  $this-&gt;cache-&gt;file-&gt;save('foo', 'bar', 10);</code>
 
+
 
+<h2 id="memcached">Memcached 缓存</h2>
 
+
 
+<p>使用分布式 Memcached 服务器 可以通过配置文件： memcached.php 来配置,该文件在 <samp>application/config/</samp> 目录下.
 
+
 
+<p>以上列举的所有方法可直接访问，不需传递特定的适配器实现给适配器加载器，如下：</p>
 
+<code>$this-&gt;load-&gt;driver('cache');<br />

+<h2 id="dummy">虚拟缓存（Dummy Cache）</h2>
 
+
 
+<p>虚拟缓存是一种总是被忽略的后台缓存。它不存储数据，但是若有的环境不支持你选择的缓存机制时，它可以让你的缓存代码能正常的执行。</p><p>&nbsp;</p>

+<h1>视图文件的 PHP 替代语法</h1>
 
+<p>如果你不使用 CodeIgniter 的<a href="../libraries/parser.html">模板引擎</a>，则你可以在视图文件中使用原始 PHP 代码。要使 PHP 代码达到最精简并使其更容易辨认，因此建议你使用 PHP 替代语法控制结构及短标记的 echo 语句。 建议你使用 PHP 的语法为你的控制结构和简短的输出标签。如果你还不熟悉这个语法，下面你将学会如何从代码中消灭大括号和&ldquo;echo&rdquo;语句。</p>
 
+<h2>自动短标记支持</h2>
 
+<p><strong>注：</strong>如果你发现本页描述的语法在你的服务器上不工作，它可能是&ldquo;短标记&rdquo;在你的 PHP ini 文件中禁用了。CodeIgniter 可以重写所有短标记，让你使用这个语法，即使你的服务器不支持它。这个特性可以在你的 <dfn>config/config.php</dfn> 文件中打开（$config['rewrite_short_tags']）。</p>
 
+<p class="important">请注意，如果你使用这个特性，如果在你的<strong>视图文件</strong>中发生 PHP 错误，则错误信息和行号将无法准确显示。相反，所有的错误将显示为 <kbd>eval &#40;&#41;</kbd> 的错误。</p>
 
+<h2>替代 Echo</h2>
 
+<p>正常的 echo 和 print 输出一般是这样的形式：</p>
 
+<p><code>&lt;?php echo $variable; ?&gt;</code></p>
 
+<p>使用替代语法，你能改成这样的形式：</p>
 
+<p><code>&lt;?=$variable?&gt;</code></p>
 
+<h2>替代控制结构</h2>
 
+<p>控制结构，像 <var>if</var>，<var>for</var>，<var>foreach</var>，和 <var>while</var> 也可以写成简化的形式。这里是一个用 foreach 的例子：</p>
 
+<p><code>&lt;ul&gt;<br />
 
+<br />
 
+<var>&lt;?php foreach ($todo as $item): ?&gt;</var><br />
 
+<br />
 
+&lt;li&gt;<var>&lt;?=$item?&gt;</var>&lt;/li&gt;<br />
 
+<br />
 
+<var>&lt;?php endforeach; ?&gt;</var><br />
 
+<br />
 
+&lt;/ul&gt;</code></p>
 
+<p>注意，这里没有大括号。相反，结束大括号被替换成了 <var>endforeach</var>。上面列出的每一个控制结构也有相似的关闭语法：<var>endif</var>，<var>endfor</var>，<var>endforeach</var> 和 <var>endwhile</var>。</p>
 
+<p>并且在每个结构以后注意不要使用分号(除了最后一个)，用冒号。这是很重要的！</p>
 
+<p>这有另一个例子，使用 if/elseif/else。注意冒号：</p>
 
+<p><code><var>&lt;?php if ($username == 'sally'): ?&gt;</var><br />
 
+<br />
 
+&nbsp;&nbsp;&nbsp;&lt;h3&gt;Hi Sally&lt;/h3&gt;<br />
 
+<br />
 
+<var>&lt;?php elseif ($username == 'joe'): ?&gt;</var><br />
 
+<br />
 
+&nbsp;&nbsp;&nbsp;&lt;h3&gt;Hi Joe&lt;/h3&gt;<br />
 
+<br />
 
+<var>&lt;?php else: ?&gt;</var><br />
 
+<br />
 
+&nbsp;&nbsp;&nbsp;&lt;h3&gt;Hi unknown user&lt;/h3&gt;<br />
 
+<br />
 
+<var>&lt;?php endif; ?&gt;</var></code></p><p>&nbsp;</p>

+<h1>自动装载资源</h1>
 
+<p>CodeIgniter 带有"自动装载"功能可以允许系统每次运行时自动初始化类库、辅助函数和模型。如果你需要某些资源在整个应用程序中全局使用，为方便起见可以考虑自动装载它们。</p>
 
+<p>下列项目可以自动装载：</p>
 
+<ul>
 
+    <li>“libraries”文件夹中的核心类</li>
 
+    <li>“helper”文件夹中的辅助函数</li>
 
+    <li>“config”文件夹中自定义配置文件</li>
 
+    <li>“system/language”文件夹中的语言包</li>
 
+    <li>“models”文件夹中的模型</li>
 
+</ul>
 
+<p>要自动装载资源，打开 <var>application/config/autoload.php</var> 文件，然后将你想要自动装载的项目添加到 <samp>autoload</samp> 数组中，你会发现该文件中对应于上面每个项目类型指示。</p>
 
+<p class="important"><strong>注意：</strong>增加项目到自动装载数组中的时候，不要包括文件扩展名(.php)。</p><p>&nbsp;</p>

+<h1>网页缓存</h1>
 
+
 
+<p>Codeigniter 支持缓存技术，以达到最快的速度。</p>
 
+
 
+<p>尽管CI已经相当高效了，但是网页中的动态内容、主机的内存CPU 和数据库读取速度等因素直接影响了网页的加载速度。
 
+依靠网页缓存，你的网页可以达到近乎静态网页的加载速度，因为他们将程序输出的结果保存到硬盘上了。</p>
 
+
 
+
 
+<h2>缓存是怎么工作的？</h2>
 
+
 
+<p>
 
+CI支持每个页面单独缓存，而且可以设置缓存更新时间。当一个网页第一次被加载的时候，缓存文件将被保存到<dfn>application/cache</dfn>文件夹。
 
+下次访问的时候，系统就会直接读取缓存文件，然后返回给用户的浏览器。如果缓存文件过期，它将被删除并重新生成。</p>
 
+
 
+<p>注意：Benchmark 标签在使用了缓存的页面仍然可用。</p>
 
+
 
+<h2>启动缓存</h2>
 
+
 
+<p>启用缓存功能，只需要将下面的代码放入你的任何一个控制器(controller)的方法(function)内：</p>
 
+
 
+<code>$this-&gt;output-&gt;cache(<var>n</var>);</code>
 
+
 
+<p>其中 <var>n</var> 是你希望缓存更新的 <strong>分钟</strong> 数。可以使用 m/60 来精确到秒，例如 1/60 ，则是精确到  1秒</p>
 
+
 
+<p>上面的代码可以放到任何一个 function 里面。他的出现顺序对缓存并没有影响，所以将它放在你认为最合乎逻辑的地方。一旦上面的代码放到了控制器的方法中，页面就会被缓存。</p>
 
+
 
+<p class="important"><strong>警告:</strong> 由于CI存储缓存文件的方式，只有通过 <a href="views.html">view</a> 文件的输出才能被缓存。</p>
 
+<p class="important"><strong>注意:</strong> 在缓存文件产生之前，请确保 <dfn>application/cache</dfn> 文件夹可写。</p>
 
+
 
+<h2>清除缓存</h2>
 
+
 
+<p>如果你不再想使用缓存，仅需将上面的代码从你的controller里面删除即可。注意:
 
+这样做并不能让缓存文件立即消失，它将会自动过期并被删除。如果你想立即删除那些文件，就必须自己动手了。</p><p>&nbsp;</p>

+<h1>以CLI方式运行</h1>
 
+
 
+<p>
 
+  除了可以在浏览器中通过URL调用一个 <a href="controllers.html">控制器</a> 外，也可以通过命令行接口(CLI)调用。
 
+</p>
 
+
 
+
 
+<ul>
 
+<li><a href="#what">什么是CLI？</a></li>
 
+<li><a href="#why">为什么使用这种方式？</a></li>
 
+<li><a href="#how">它如何工作？</a></li>
 
+</ul>
 
+
 
+
 
+<a name="what"></a>
 
+<h2>什么是CLI？</h2>
 
+
 
+<p><dfn>命令行接口是一种基于文本的和计算机交互的方式。</dfn> 如果想查看更详细说明，请看<a href="#">Wikipedia article</a>.</p>
 
+
 
+<a name="why"></a>
 
+
 
+<h2>为什么使用命令行？</h2>
 
+
 
+<p>
 
+  虽然不是必须的，但在某些情况下我们会用到命令行</p>
 
+
 
+<ul>
 
+  <li>使用 cron 定时运行任务而不需要使用 wget 或 curl</li>
 
+  <li>通过检查 <kbd>$this-&gt;input-&gt;is_cli_request()</kbd> 让你的 cron 任务无法通过网址访问到</li>
 
+  <li>让交互式任务可以做设置权限、清空缓存、执行备份等操作</li>
 
+  <li>与其他语言进行集成。比如一个 C++ 脚本可以调用一条指令来运行你模型中的代码！</li>
 
+</ul>
 
+
 
+<a name="how"></a>
 
+<h2>让我们试一试：Hello World!</h2>
 
+
 
+<p>首先创建一个简单的控制器。使用你的文本编辑器，创建一个叫做 <dfn>tools.php</dfn> 的文件，并且输入如下代码：</p>
 
+
 
+<textarea class="textarea" style="width:100%" cols="50" rows="10">
 
+&lt;?php
 
+class Tools extends CI_Controller &#123;
 
+
 
+  public function message($to = 'World')
 
+  &#123;
 
+    echo "Hello &#123;$to&#125;!".PHP_EOL;
 
+  &#125;
 
+&#125;
 
+?&gt;
 
+</textarea>
 
+
 
+<p>然后将这个文件保存到你的 <dfn>application/controllers/</dfn> 文件夹里。</p>
 
+
 
+<p>现在正常情况下你可以通过你网站的 URL 来访问它：</p>
 
+
 
+<code>example.com/index.php/<var>tools</var>/<var>message</var>/<var>to</var></code>
 
+
 
+<p>除此之外，我们也可以在 Mac/Linux 中打开终端，或者在 Windows 下进入“运行”输入“cmd”，并进入我们的 CodeIgniter 项目的目录。</p>
 
+
 
+<blockquote>
 
+  $ cd /path/to/project;<br/>
 
+  $ php index.php tools message
 
+</blockquote>
 
+
 
+<p>如果你跟着一步步下来，你应该会看到 <samp>Hello World!</samp>。</p>
 
+
 
+<blockquote>
 
+  $ php index.php tools message "John Smith"
 
+</blockquote>
 
+
 
+<p>这里我们像使用 URL 参数一样给它传递了一个参数。“John Smith”作为一个参数被传递了，并且输出也变成：<samp>Hello John Smith!</samp>。</p>
 
+
 
+<h2>就是这样！</h2>
 
+
 
+<p>简单的来说，这就是全部你需要知道的有关命令行中使用控制器的事情了。记住这只是一个普通的控制器，所以路由和 _remap 也照样工作。</p><p>&nbsp;</p>

+<h1>公共函数</h1>
 
+
 
+<p  class="important">注：本条为本人添加。公共函数位于 system/core/Common.php 文件中，大家可以在这里定义自己的公共函数。--IT不倒翁</p>
 
+<p>CodeIgniter 使用了一些全局定义的函数来完成操作，在任何情况下你都能够使用这些函数。使用他们不需要载入任何类库或辅助函数。</p>
 
+
 
+
 
+<h2>is_php('<var>version_number</var>')</h2>
 
+
 
+<p>is_php() 判断正在使用的PHP的版本号是否高于你所提供的 <var>version_number</var> 。</p>
 
+
 
+<code>if (is_php('5.3.0'))<br />
 
+&#123;<br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;$str = quoted_printable_encode($str);<br />
 
+&#125;</code>
 
+
 
+<p>如果已安装的PHP版本号等于或高于你所提供的版本号，本函数将返回布尔值 <kbd>TRUE</kbd>。如果安装的PHP版本号低于你所提供的那个版本号，本函数将返回 <kbd>FALSE</kbd>。</p>
 
+
 
+
 
+<h2>is_really_writable('<var>path/to/file</var>')</h2>
 
+
 
+<p>在Windows平台，is_writable()函数在实际没有文件写权限时也返回真。那是因为，只有文件有只读属性时，操作系统才向PHP报告为假。这个函数依靠对文件的先行写入来判断是否真的具有写权限。 通常情况下，只有在这个信息不可靠的平台上才推荐使用。</p>
 
+<p><span style="color:red;">注:</span>此函数也可用于判断文件夹是否有可写权限。</p>
 
+<code>if (is_really_writable('file.txt'))<br />
 
+&#123;<br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;echo &quot;I could write to this if I wanted to&quot;;<br />
 
+&#125;<br />
 
+else<br />
 
+&#123;<br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;echo &quot;File is not writable&quot;;<br />
 
+&#125;</code>
 
+
 
+
 
+<h2>config_item('<var>item_key</var>')</h2>
 
+
 
+<p>尽管使用config_item()函数能够取得单个配置信息，但是<a href="../libraries/config.html">配置类</a>是访问这些信息的优选方式。更多信息请见类库参考。</p>
 
+<p><span style="color:red;">注:</span>此函数获取的是从config文件直接获取的值，无法取得<a href="../libraries/config.html">配置类</a> set_item() 函数变更后的值。</p>
 
+<h2>show_error('<var>message</var>'), show_404('<var>page</var>'), log_message('<var>level</var>', '<samp>message</samp>')</h2>
 
+
 
+<p>这些函数在<a href="errors.html">错误处理</a>中描述。</p>
 
+
 
+
 
+<h2>set_status_header(<var>code</var>, '<var>text</var>');</h2>
 
+
 
+<p>允许你手动设置服务器状态头(header)。例如:</p>
 
+
 
+<code>set_status_header(401);<br />
 
+// 将header设置为:  Unauthorized</code>
 
+
 
+<p><a href="#" target="_blank">单击这里</a> 查看全部的header列表。</p>
 
+
 
+<h2>remove_invisible_characters(<var>$str</var>)</h2>
 
+<p>这个函数能防止在ASCII字符之间插入空字符，如Java\0script.</p>
 
+
 
+<h2>html_escape(<var>$mixed</var>)</h2>
 
+<p>利用此功能可以方便的使用htmlspecialchars()函数。它接受字符串和数组。有助于防止跨站脚本攻击（XSS）。</p><p>&nbsp;</p>

+<h2>什么是控制器？</h2>
 
+<p><dfn>简而言之，一个控制器就是一个类文件，是以一种能够和 URI 关联在一起的方式来命名的。</dfn></p>
 
+<p>假设这个 URI:</p>
 
+<code>example.com/index.php/<var>blog</var>/</code>
 
+<p>在上面的例子中，CodeIgniter 将尝试寻找并装载一个名为 <dfn>blog.php</dfn> 的控制器。</p>
 
+<p><strong>当控制器的名字匹配 URI 的第一段时，它将被装载。</strong></p>
 
+<p><a name="hello"></a></p>
 
+<h2>让我们试试看:&nbsp; Hello World！</h2>
 
+<p>我们来创建一个简单的控制器，以便更直观地了解其工作原理。使用你的文本编辑器，创建一个名为 <dfn>blog.php</dfn> 的文件，然后输入下列代码：</p>
 
+<p><textarea class="textarea" style="width: 100%" rows="14" cols="50">&lt;?php
 
+class Blog extends CI_Controller &#123;
 
+
 
+ function __construct()
 
+ &#123;
 
+  parent::__construct();
 
+ &#125;
 
+
 
+ public function index()
 
+ &#123;
 
+  echo 'Hello World！';
 
+ &#125;
 
+&#125;
 
+?&gt;</textarea></p>
 
+<p>然后保存文件到 <dfn>application/controllers/</dfn> 文件夹。</p>
 
+<p>现在使用类似这样的 URL 访问你的站点：</p>
 
+<code>example.com/index.php/<var>blog</var>/</code>
 
+<p>如果你做的没错，你应该看到<samp>Hello World！</samp>.</p>
 
+<p>注意：类名必须以大写字母开头。换句话说，这是有效的：</p>
 
+<p><code>&lt;?php<br />
 
+class <var>Blog</var> extends CI_Controller &#123;<br />
 
+<br />
 
+&#125;<br />
 
+?&gt;</code></p>
 
+<p>下面的blog首字母b小写，是属于<strong>无效</strong>的写法：</p>
 
+<p><code>&lt;?php<br />
 
+class <var>blog</var> extends CI_Controller &#123;<br />
 
+<br />
 
+&#125;<br />
 
+?&gt;</code></p>
 
+<p>同时，始终确保你的控制器<dfn>扩展</dfn>自父控制器类，以便它能够继承其所有的方法。</p>
 
+<p><a name="functions"></a></p>
 
+<h2>方法</h2>
 
+<p>上面的例子中用到的方法名是 <dfn>index()</dfn>。如果 URI 的<strong>第二部分</strong>为空的话，会默认载入 &ldquo;index&rdquo; 方法。也可以将地址写成这样来访问 &ldquo;Hello World&rdquo;：</p>
 
+<code>example.com/index.php/<var>blog</var>/<samp>index</samp>/</code>
 
+<p><strong>URI 的第二部分是用来决定调用控制器中哪个方法的。</strong></p>
 
+<p>我们再来试试。在你的控制器中加入一个新的方法：</p>
 
+<p><textarea class="textarea" style="width: 100%" rows="19" cols="50">&lt;?php
 
+class Blog extends CI_Controller &#123;
 
+
 
+ function __construct()
 
+ &#123;
 
+  parent::__construct();
 
+ &#125;
 
+
 
+ public function index()
 
+ &#123;
 
+  echo 'Hello World！';
 
+ &#125;
 
+
 
+ public function comments()
 
+ &#123;
 
+  echo '看这里！';
 
+ &#125;
 
+&#125;
 
+?&gt;</textarea></p>
 
+<p>现在在地址栏中输入下面的内容来访问 <dfn>comments</dfn> 方法：</p>
 
+<code>example.com/index.php/<var>blog</var>/<samp>comments</samp>/</code>
 
+<p>你应该看到新的信息了：看这里！</p>
 
+<p><a name="passinguri"></a></p>
 
+<h2>将 URI 片段传递给方法</h2>
 
+<p>如果你的 URI 超过两个部分，那么超过的将被作为参数传递给方法。</p>
 
+<p>举例来说，如果你的 URI 是这样的：</p>
 
+<code>example.com/index.php/<var>products</var>/<samp>shoes</samp>/<kbd>sandals</kbd>/<dfn>123</dfn></code>
 
+<p>URI 的第3和第4部分会被传递给你的方法（&ldquo;sandals&rdquo; 和 &ldquo;123&rdquo;）：</p>
 
+<p><code>&lt;?php<br />
 
+class Products extends CI_Controller &#123;<br />
 
+<br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;public function shoes($sandals, $id)<br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;&#123;<br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;echo $sandals;<br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;echo $id;<br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;&#125;<br />
 
+&#125;<br />
 
+?&gt; </code></p>
 
+<p>上面的方法调用时必须给两个相应的参数，要不然会出错。当然你也可以像下面这样写，就不用在调用的时候给参数了！</p>
 
+<p><code>&lt;?php<br />
 
+class Products extends CI_Controller &#123;<br />
 
+<br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;public function shoes($sandals='Test', $id=1)<br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;&#123;<br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;echo $sandals;<br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;echo $id;<br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;&#125;<br />
 
+&#125;<br />
 
+?&gt; </code></p>
 
+<p class="important"><strong>注意：</strong>如果你使用 <a href="routing.html">URI 路由</a>特性，则传递到方法中的 URI 片段将被重新路由一次。</p>
 
+
 
+<a name="default"></a>
 
+<h2>定义默认控制器</h2>
 
+<p>当你的网站不存在某个URI 或者 用户直接从根目录访问的时候，CodeIgniter 会加载默认控制器。打开 <dfn>application/config/routes.php</dfn> 文件来设置默认控制器：</p>
 
+<p><code>$route['default_controller'] = '<var>Blog</var>';</code></p>
 
+<p>这里的 <var>Blog</var> 就是你希望使用的控制器的名字。如果此时你不指定任何 URI 片段来访问你的主页就会看到默认的&ldquo;Hello World&rdquo;信息。</p>
 
+
 
+<a name="remapping"></a>
 
+<h2>重新定义方法的调用规则</h2>
 
+<p>如上所述，URI 的第二片段决定会调用控制器中的哪个方法。CodeIgniter 允许你使用 <kbd>_remap()</kbd> 方法来废除这种规则：</p>
 
+<p><code>public function _remap()<br />
 
+&#123;<br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;// Some code here...<br />
 
+&#125;</code></p>
 
+<p class="important"><strong>注意：</strong>如果你的控制器中包含一个名为 <kbd>_remap() </kbd>的方法，那么不管你的 URI 中包含什么，它<strong>总会</strong>被忽略掉。这个方法会废除掉由 URI 片段来决定哪个方法被调用的规则，允许你重新定义调用方法的规则（方法的路由规则）。</p>
 
+<p>被重新定义的方法调用方式（一般是 URI 中的第二片段）将作为一个参数传递给 <kbd>_remap() </kbd>：</p>
 
+<code>public function _remap(<var>$method</var>)<br />
 
+&#123;<br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;if ($method == 'some_method')<br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;&#123;<br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;$this-&gt;$method();<br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;&#125;<br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;else<br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;&#123;<br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;$this-&gt;comments();<br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;&#125;<br />
 
+&#125;</code>
 
+
 
+<p>任何附加在该方法名称之后的段都会被视为 <kbd>_remap()</kbd> 的第二个参数（可选）。这个可选的数组参数可以与PHP的<a href="#" target="_blank">call_user_func_array</a>联用，模拟CodeIgniter的默认行为。</p>
 
+
 
+<code>public function _remap($method, $params = array())<br />
 
+&#123;<br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;$method = 'process_'.$method;<br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;if (method_exists($this, $method))<br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;&#123;<br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;return call_user_func_array(array($this, $method), $params);<br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;&#125;<br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;show_404();<br />
 
+&#125;</code>
 
+
 
+<a name="output"></a>
 
+<h2>处理输出</h2>
 
+<p>CodeIgniter 拥有一个输出类用来确保你修改的数据会自动被传递给浏览器。关于这个的更多信息可以在<a href="views.html">视图</a>和<a href="../libraries/output.html">输出类</a>里找到。有些时候，你可能想要自己发布修改一些最终的数据或是自己把它传递给浏览器。CodeIgniter 允许你给你的控制器增加一个名为 <span class="STYLE1"><strong><font color="#00620c">_output()</font></strong></span> 的方法来接收最终的数据。</p>
 
+<p><strong>注意：</strong>&nbsp;如果你的控制器包含一个 <kbd>_output()</kbd> 方法，那么它将<strong>总是</strong>被调用，而不是直接输出最终的数据。这个方法类似于OO里的析构函数，不管你调用任何方法这个方法总是会被执行。</p>
 
+<p>例如：</p>
 
+<code>public function _output($output)<br />
 
+&#123;<br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;echo $output;<br />
 
+&#125;</code>
 
+<p class="important">请注意，你的 <dfn>_output()</dfn> 将接收最终的数据。 Benchmark和内存的使用率数据将被渲染，缓存文件会被写入（如果已启用缓存），并且 HTTP 头也将被发送（如果您使用该<a href="../libraries/output.html">功能</a>），然后交给 _output() 函数。<br />
 
+<br />
 
+为了让你的控制器输出缓存正确, 它的 <dfn>_output()</dfn> 函数可以这样来写:<br />
 
+
 
+<code>if ($this-&gt;output-&gt;cache_expiration &gt; 0)<br />
 
+&#123;<br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;$this-&gt;output-&gt;_write_cache($output);<br />
 
+  &#125;</code>
 
+
 
+如果您正在使用页面执行时间和内存使用统计的功能，这可能不完全准确，因为他们不会考虑到你所做的任何进一步的动作。请在<a href="../libraries/output.html">输出类</a>参用可用的方法，来控制输出以使其在任何最终进程完成之前执行。
 
+
 
+<a name="private"></a>
 
+<h2>私有方法</h2>
 
+<p>在某些情况下，你可能想要隐藏一些方法使之无法对外查阅。将方法私有化很简单，只要在方法名字前面加一个下划线（&ldquo;_&rdquo;）做前缀就无法通过 URL 访问到了。例如，如果你有一个像这样的方法：</p>
 
+<p><code>private function _utility()<br />
 
+&#123;<br />
 
+&nbsp;&nbsp;// some code<br />
 
+&#125;</code></p>
 
+<p>那么，通过下面这样的 URL 进行访问是无法访问到的：</p>
 
+<code>example.com/index.php/<var>blog</var>/<samp>_utility</samp>/</code>
 
+
 
+<a name="subfolders"></a>
 
+<h2>如何将控制器放入子文件夹中</h2>
 
+<p>如果你在建立一个大型的应用程序，你会发现 CodeIgniter 可以很方便的将控制器放到一些子文件夹中。</p>
 
+<p>只要在 <dfn>application/controllers</dfn> 目录下创建文件夹并放入你的控制器就可以了。</p>
 
+<p><strong>注意：</strong>&nbsp; 如果你要使用某个子文件夹下的功能，就要保证 URI 的第一个片段是用于描述这个文件夹的。例如说你有一个控制器在这里：</p>
 
+<p><code>application/controllers/<kbd>products</kbd>/shoes.php</code></p>
 
+<p>调用这个控制器的时候你的 URI 要这么写：</p>
 
+<code>example.com/index.php/products/shoes/show/123</code>
 
+<p>你的每个子文件夹中需要包含一个默认的控制器，这样如果 URI 中只有子文件夹而没有具体功能的时候它将被调用。只要将你作为默认的控制器名称在 <dfn>application/config/routes.php</dfn> 文件中指定就可以了。</p>
 
+<p>CodeIgniter 也允许你使用 <a href="routing.html">URI 路由</a> 功能来重新定向 URI。</p>
 
+<h2><a name="constructors"></a>构造函数</h2>
 
+<p>如果要在你的任意控制器中使用构造函数的话，那么<strong>必须</strong>在里面加入下面这行代码：</p>
 
+<p><code>parent::__construct();</code></p>
 
+<p>这行代码的必要性在于，你此处的构造函数会覆盖掉这个父控制器类中的构造函数，所以我们要手动调用它。</p>
 
+<code>&lt;?php<br />
 
+class <kbd>Blog</kbd> extends CI_Controller &#123;<br />
 
+<br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;public function <kbd>__construct()</kbd><br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&#123;<br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<var>parent::__construct();</var><br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&#125;<br />
 
+&#125;<br />
 
+?&gt;</code>
 
+<p>如果你需要设定某些默认的值或是在实例化类的时候运行一个默认的程序，那么构造函数在这方面就非常有用了。<br />
 
+构造函数并不能返回值，但是可以用来设置一些默认的功能。</p>
 
+
 
+<a name="reserved"></a>
 
+<h2>已保留的方法名称</h2>
 
+
 
+<p>因为你添加的控制器类继承了主要的应用程序控制器，所以你要小心你的方法名不要和那个类中的方法名一样了，否则你的方法会覆盖原有的。详细信息请查看<a href="reserved_names.html">保留字</a>部分。</p>
 
+
 
+<h2>就这样了！</h2>
 
+<p>OK，总的来说，这就是关于控制器的所有内容了。</p><p>&nbsp;</p>

+<h1>创建核心系统类</h1>
 
+
 
+<p>每次CodeIgniter运行时都有很多基础类作为核心框架的一部分被自动初始化.但你也可以使用经过你修改的类来替换甚至扩展这些原始的核心系统类.</p>
 
+
 
+<p><strong>大多数用户一般不会有这种需求,但对于那些想较大幅度的改变CodeIgniter的人来说,我们依然提供了替换和扩展核心系统类的选择.</strong>
 
+</p>
 
+
 
+<p class="important"><strong>注意:</strong>&nbsp; 改变系统核心类会产生很大影响,所以在你做之前必须清楚地知道自己正在做什么.</p>
 
+
 
+
 
+<h2>系统类清单</h2>
 
+
 
+<p>以下是系统核心文件的清单,它们在每次CodeIgniter启动时被调用:</p>
 
+
 
+<ul>
 
+<li>Benchmark</li>
 
+<li>Config</li>
 
+<li>Controller</li>
 
+<li>Exceptions</li>
 
+<li>Hooks</li>
 
+<li>Input</li>
 
+<li>Language</li>
 
+<li>Loader</li>
 
+<li>Log</li>
 
+<li>Output</li>
 
+<li>Router</li>
 
+<li>URI</li>
 
+<li>Utf8</li>
 
+</ul>
 
+
 
+<h2>替换核心类</h2>
 
+
 
+<p>要使用你自己的系统类替换默认类只需简单的将你自己的 .php 文件放入本地文件夹 <dfn>application/core</dfn></p>
 
+
 
+<code>application/core/<dfn>some-class.php</dfn></code>
 
+
 
+<p>如果这个文件夹不存在你可以自己创建一个.</p>
 
+
 
+<p>只要你自定义的文件名与默认的完全一样,它就会自动替换原有的类.</p>
 
+
 
+<p>要注意的是你自定义的类必须以CI作为前缀,例如你自己建立了<kbd>Input.php</kbd>类的名字必须是:</p>
 
+
 
+<code>
 
+class CI_Input &#123;<br /><br />
 
+
 
+&#125;
 
+</code>
 
+
 
+
 
+
 
+<h2>扩展核心类</h2>
 
+
 
+<p>如果你需要在现有类库中加入一两个新的功能,那就完全不必要替换整个类库文件.你只需简单地扩展(继承)现有的类,扩展一个类就像在类中增加一些例外:</p>
 
+
 
+<ul>
 
+
 
+<li>扩展的类必须申明由父类扩展而来.</li>
 
+<li>新扩展的类所在的文件必须以 <kbd>MY_</kbd> 为前缀(这个选项是可配置的,下面有说明).</li>
 
+</ul>
 
+
 
+<p>例如,要扩展原有的<kbd>Input</kbd> 类,你应该新建一个文件名为<dfn>application/core/</dfn><kbd>MY_Input.php</kbd>, 并按如下声明你的类:</p>
 
+
 
+<code>
 
+class MY_Input extends CI_Input &#123;<br /><br />
 
+
 
+&#125;</code>
 
+
 
+<p>注意:如果你需要在类中使用构造函数,你必须在构造函数中显式继承父类构造函数:</p>
 
+
 
+<code>
 
+class MY_Input extends CI_Input &#123;<br />
 
+<br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;function __construct()<br />
 
+
 
+&nbsp;&nbsp;&nbsp;&nbsp;&#123;<br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;parent::__construct();<br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;&#125;<br />
 
+&#125;</code>
 
+
 
+<p class="important"><strong>Tip:</strong>&nbsp; 所有在你的新类中定义的函数如果与父类中函数的命名完全一样,这些函数就能取代父类中原有的函数
 
+(这也被称为"方法覆盖").这允许你在本质上改变CodeIgniter的核心.</p>
 
+
 
+<p>如果你扩展了控制器核心类，那么也要在你的应用程序控制器的构造函数中使用这个新类。</p>
 
+
 
+<code>class Welcome extends MY_Controller &#123;<br />
 
+<br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;function __construct()<br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;&#123;<br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;parent::__construct();<br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;&#125;<br />
 
+<br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;function index()<br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;&#123;<br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;$this-&gt;load-&gt;view('welcome_message');<br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;&#125;<br />
 
+&#125;</code>
 
+
 
+<h3>自定义前缀</h3>
 
+
 
+<p>要设定你自己的子类前缀,请打开<dfn>application/config/config.php</dfn> 文件并找到这一项:</p>
 
+
 
+<code>$config['subclass_prefix'] = 'MY_';</code>
 
+
 
+<p>请注意所有原始CodeIgniter类库以 <kbd>CI_</kbd> 作为前缀,所以请勿以CI_作为你自己的前缀.<b>所有的扩展核心类必须放到core目录中！</b></p><p>&nbsp;</p>

+<h1>创建类库</h1>
 
+
 
+<p>当我们使用术语"类库"时,我们一般指的是位于<kbd>libraries</kbd> 文件夹中的类,它们在wiki的"类库参考"这个板块被讨论.在当前这个话题中,我们将讨论如何在 <dfn>application/libraries</dfn> 文件夹中建立你自己的类库,并使它们与全框架的资源维持分离.</p>
 
+
 
+<p>作为一个额外的功能,当你需要在原始类中简单地添加一些功能时,CodeIgniter能使你的类库<kbd>extend</kbd> 自原始类.你甚至可以通过在<dfn>application/libraries</dfn>文件夹下安放同名类库文件的方法来完全替换原始类.</p>
 
+
 
+<p>总之:</p>
 
+
 
+<ul>
 
+<li>你可以创建全新的类库.</li>
 
+<li>你可以扩展原始类库.</li>
 
+<li>你可以替换原始类库.</li>
 
+</ul>
 
+
 
+<p>以下页面将深入介绍这三个概念.</p>
 
+
 
+<p class="important"><strong>注意:</strong> 除了数据库类无法被扩展或替换，剩余其他类均可。</p>
 
+
 
+
 
+<h2>建立你的类库文件</h2>
 
+
 
+<p>你的类库文件必须保存在 <dfn>application/libraries</dfn> 文件夹,CodeIgniter将在这个文件夹中寻找并初始化它们.</p>
 
+
 
+
 
+<h2>命名约定</h2>
 
+
 
+<ul>
 
+<li>文件名首字母大写. 例如:&nbsp; <dfn>Myclass.php</dfn></li>
 
+
 
+<li>类声明首字母大写. 例如:&nbsp;  <kbd>class Myclass</kbd></li>
 
+<li>类的名字和文件名应相同.</li>
 
+</ul>
 
+
 
+
 
+<h2>类文件</h2>
 
+
 
+<p>所有的类应有基础原型(注意,这里我们以 <kbd>Someclass</kbd> 这个名字为例):</p>
 
+
 
+<code>&lt;?php  if (!defined('BASEPATH')) exit('No direct script access allowed');
 
+<br /><br />
 
+class Someclass &#123;<br />
 
+<br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;public function some_function()<br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;&#123;<br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;&#125;<br />
 
+&#125;<br /><br />
 
+/* End of file Someclass.php */</code>
 
+
 
+<h2>使用你自己的类</h2>
 
+
 
+<p>在所有的<a href="controllers.html">Controller</a> 函数中,你可以用以下的标准方式初始化你的类:</p>
 
+
 
+<code>$this-&gt;load-&gt;library('<kbd>someclass</kbd>');</code>
 
+
 
+<p>当 <em>someclass</em> 是文件名时,不用加上".php"扩展名.这里名字不分大小写.</p>
 
+
 
+<p>一旦你自定义的类加载完毕,你可以通过以下方式调用类,注意使用 <kbd>小写</kbd> 的名字:</p>
 
+
 
+<code>$this-&gt;<kbd>someclass</kbd>-&gt;some_function();&nbsp; // 对象的实例名永远都是小写的
 
+</code>
 
+
 
+
 
+
 
+<h2>在初始化自定义类时传递参数</h2>
 
+
 
+<p>当初始化类库时，你可以通过第二个参数动态的传递数组到类的构造函数中去:</p>
 
+
 
+<code>
 
+$params = array('type' => 'large', 'color' => 'red');<br />
 
+<br />
 
+$this-&gt;load-&gt;library('Someclass', <kbd>$params</kbd>);</code>
 
+
 
+<p>当你使用这个特性时,你必须为类的构造函数加上参数:</p>
 
+
 
+<code>&lt;?php  if (!defined('BASEPATH')) exit('No direct script access allowed');<br />
 
+
 
+<br />
 
+class Someclass &#123;<br />
 
+<br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;public function __construct($params)<br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;&#123;<br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;// Do something with $params<br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;&#125;<br />
 
+&#125;<br /><br />
 
+?&gt;</code>
 
+
 
+<p class="important">你也可以传递存于配置文件中的参数.你只需简单的建立一个与 <kbd>类文件名</kbd>相同的config文件,并保存在 <dfn>application/config/</dfn> 文件夹中.注意当你通过上文所述的方式动态传递参数时,config文件中的选项将不起作用.</p>
 
+
 
+
 
+<h2>在你自定义的类库中初始化CodeIgniter资源</h2>
 
+
 
+<p>要你自定义的类库中访问CodeIgniter的原始资源,你必须使用 <kbd>get_instance()</kbd> 函数.这个函数返回一个CodeIgniter super object.</p>
 
+
 
+<p>一般来说在你的控制器函数中你可以通过 <kbd>$this</kbd> 调用任何可用的CodeIgniter函数:</p>
 
+
 
+<code>
 
+<strong>$this</strong>-&gt;load-&gt;helper('url');<br />
 
+<strong>$this</strong>-&gt;load-&gt;library('session');<br />
 
+<strong>$this</strong>-&gt;config-&gt;item('base_url');<br />
 
+//etc.
 
+</code>
 
+
 
+<p><kbd>$this</kbd>, 只直接作用在你自己的控制器,模型和视图中.当你在自定义类中想使用CodeIgniter原始类时,你可以这样做:</p>
 
+
 
+
 
+<p>首先,定义CodeIgniter对象赋给一个变量:</p>
 
+
 
+<code>$CI =& get_instance();</code>
 
+
 
+<p>一旦定义某个对象为一个变量,你就可以使用那个变量名 <em>取代</em>  <kbd>$this</kbd>:</p>
 
+
 
+<code>
 
+$CI =& get_instance();<br /><br />
 
+$CI-&gt;load-&gt;helper('url');<br />
 
+$CI-&gt;load-&gt;library('session');<br />
 
+$CI-&gt;config-&gt;item('base_url');<br />
 
+//etc.
 
+</code>
 
+
 
+<p class="important"><strong>注意:</strong> 你将注意到get_instance()这个函数通过被引用的方式被传递:<br /><br />
 
+<var>$CI =&amp; get_instance();</var>
 
+<br /><br />
 
+<kbd>这十分重要.</kbd> 通过引用的方式赋给变量将使用原始的 CodeIgniter 对象，而不是创建一个副本。</p>
 
+
 
+
 
+<h2>用你自己的类替换原始类</h2>
 
+
 
+<p>简单的将你自己的类命名为与原始类一样就能使CodeIgniter使用这个新类．要使用这个特性，文件名与类声明必须与原始类完全一致。例如，要替换原始的 <kbd>Email</kbd> 类库。你必须创建一个文件<dfn>application/libraries/Email.php</dfn>, 并按如下方式声明类:</p>
 
+
 
+<code>
 
+class CI_Email &#123;<br /><br />
 
+
 
+&#125;</code>
 
+
 
+<p>注意大多数原始类以<kbd>CI_</kbd>为前缀.</p>
 
+
 
+<p>你可以只用标准载入函数来载入你自己的类:</p>
 
+
 
+<code>$this-&gt;load-&gt;library('<kbd>email</kbd>');</code>
 
+
 
+<p class="important"><strong>注意:</strong> 这个时候Database无法替换为你自定义的类.</p>
 
+
 
+
 
+<h2>扩展现有类</h2>
 
+
 
+<p>如果你需要在现有类库中加入一两个新的功能,那就完全不必要替换整个类库文件.你只需简单地扩展(继承)现有的类,扩展一个类就像在类中增加一些例外:</p>
 
+
 
+<ul>
 
+<li>扩展的类必须申明由父类扩展而来.</li>
 
+<li>新扩展的类所在的文件必须以 <kbd>MY_</kbd> 为前缀(这个选项是可配置的,下面有说明).</li>
 
+
 
+</ul>
 
+
 
+<p>例如，要扩展原始类 <kbd>Email</kbd> 类你要建立文件 <dfn>application/libraries/</dfn><kbd>MY_Email.php</kbd>, 并按如下方式在文件中声明:</p>
 
+
 
+<code>
 
+class MY_Email extends CI_Email &#123;<br /><br />
 
+
 
+&#125;</code>
 
+
 
+<p>注意:如果你需要在类中使用构造函数,你必须在构造函数中显式继承父类构造函数:</p>
 
+
 
+
 
+<code>
 
+class MY_Email extends CI_Email &#123;<br />
 
+<br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;public function __construct()<br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;&#123;<br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;parent::__construct();<br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;&#125;<br />
 
+
 
+&#125;</code>
 
+
 
+
 
+<h3>载入你的子类</h3>
 
+
 
+<p>要载入扩展子类，你应该使用标准字符名.  请不要使用前缀.  例如,要载入上文说过的email扩展子类，你应该这样写:</p>
 
+
 
+<code>$this-&gt;load-&gt;library('<kbd>email</kbd>');</code>
 
+
 
+<p>扩展子类一旦被载入，就能像一般的类一样使用它们.  Email类中的所有函数就能被调用:</p>
 
+
 
+<code>$this-&gt;<kbd>email</kbd>-&gt;some_function();</code>
 
+
 
+<h3>设定自定义前缀</h3>
 
+
 
+<p>要设定你自己的子类前缀,请打开 <dfn>application/config/config.php</dfn> 文件并找到这一项:</p>
 
+
 
+<code>$config['subclass_prefix'] = 'MY_';</code>
 
+
 
+<p>注意所有原始CodeIgniter类库以 <kbd>CI_</kbd> 作为前缀,所以请勿以CI_作为你自己的前缀.</p><p>&nbsp;</p>

+<h1>关于 CodeIgniter</h1>
 
+
 
+<p>CodeIgniter 最早是由 <a href="#">Rick Ellis</a> 开发（<a href="#">EllisLab 公司</a>的 CEO）。这个框架是为真实应用而编写的，集成了很多类库、辅助函数(helpers)以及从 <a href="#">ExpressionEngine</a> 借用的子系统。</p>
 
+
 
+<p>CodeIgniter 当前由“ExpressionEngine 开发团队”开发并维护。<br />
 
+Bleeding edge development is spearheaded by the handpicked contributors of the Reactor Team.</p>
 
+
 
+<p>来自 Ruby on Rails 的灵感启发我们创造了一个 PHP 框架，并且将框架的概念引入到网络社区的一般意识中。</p><p>&nbsp;</p>

+<h1>使用 CodeIgniter 适配器</h1>
 
+
 
+<p>适配器是一种特殊的库，它有一个父类和任意数量的子类。子类可以访问其父类元素，但不能访问其兄弟类的元素。在你的<a href="controllers.html">控制器</a>中，适配器为类库提供了一种优雅的语法，因此类库会就此获益甚至会需要分解成离散的类。</p>
 
+
 
+<p>适配器的源文件存放在<dfn>system/libraries</dfn> 目录下, 命名一个和类名字相同的文件夹，文件夹下存放该类。同时在该文件夹中，有一个子文件夹叫做  <kbd>drivers</kbd>在其中包含了所有的子类。</p>
 
+
 
+<p>要使用一个适配器，你需要在一个控制器里用如下的初始化函数初始它：</p>
 
+
 
+<code>$this-&gt;load-&gt;driver('<var>class name</var>'); </code>
 
+
 
+<p>这里的<var>class name</var> 是你想加载的适配器的名字。 比如说你想加载一个叫做"Some Parent"的适配器，你可以这样：</p>
 
+
 
+<code>$this-&gt;load-&gt;driver('<var>some_parent</var>');</code>
 
+
 
+<p>适配器类中的方法可以用如下的方式来调用:</p>
 
+
 
+<code>$this-&gt;some_parent-&gt;some_method();</code>
 
+
 
+<p>这些作为子类的适配器能直接通过父类调用，而不用初始化。</p>
 
+
 
+<code>$this-&gt;some_parent-&gt;child_one-&gt;some_method();<br />
 
+$this-&gt;some_parent-&gt;child_two-&gt;another_method();</code>
 
+请查看缓存适配器的<a href="../drivers/caching.html#file">文件缓存</a>使用方法
 
+<h2>创建自己的适配器</h2>
 
+
 
+<p>如果想创建自己的适配器，请阅读用户手册中关于<a href="creating_drivers.html">创建适配器</a>的部分.</p><p>&nbsp;</p>

+<h1>处理多环境</h1>
 
+
 
+<p>
 
+    开发者通常希望就开发环境或者生产环境的不同而有不同的系统行为(响应)。
 
+  例如，输出冗长的错误对开发过程很有用，但是当项目上线时这可能会造成一些安全问题。
 
+</p>
 
+
 
+<h2>ENVIRONMENT 常量</h2>
 
+
 
+<p>
 
+    默认情况下 CodeIgniter 把环境常量设置为
 
+    '<kbd>development</kbd>'. 在 index.php 文件的顶部，你会看到:
 
+</p>
 
+
 
+<code>
 
+define('<var>ENVIRONMENT</var>', '<var>development</var>');
 
+</code>
 
+
 
+<p>
 
+  除了影响一些基本框架行为外（查看下一章节），
 
+  你还可以在开发过程中用这个常量来区分正在运行的是哪个环境。
 
+</p>
 
+
 
+<h2>对默认框架行为的影响</h2>
 
+
 
+<p>
 
+    CodeIgniter 系统有些地方使用了 <kbd>ENVIRONMENT</kbd> 常量。
 
+    在这一章节会说明默认情况下环境常量对框架行为的影响。
 
+</p>
 
+
 
+<h3>错误报告</h3>
 
+
 
+<p>
 
+    设置 <kbd>ENVIRONMENT</kbd> 常量为 '<kbd>development</kbd>' 值将会允许所有PHP错误报告都输出到浏览器。
 
+  相反的，设置常量为 '<kbd>production</kbd>' 将会禁止所有错误报告的输出。
 
+  在产品中禁用错误报告是一个 <a href="security.html">不错的安全措施</a>。
 
+</p>
 
+
 
+<h3>配置文件</h3>
 
+
 
+<p>
 
+    可选的，你可以让 CodeIgniter 加载特定环境的配置文件。
 
+  这可能会对管理如在多环境使用不同API密钥这样的事情很有用。
 
+  这在文档<a href="../libraries/config.html#environments">配置类</a>“环境”一节有详细的说明。

+<h1>错误处理</h1>
 
+
 
+<p>在你的程序里使用以下的函数，CodeIgniter将允许你建立自己的错误报告。另外，他有一个错误记录类能够将错误和调试信息保存为文本文档。</p>
 
+
 
+<p class="important"><strong>注意:</strong> 在默认的情况下, CodeIgniter 会显示所有的PHP错误.　但是当你开发程序结束时，你可能想要改变这个情况. 你会发现在index.php文件顶端有这个函数<dfn>error_reporting()</dfn>，通过它可以进行对错误的设置。 即使你关闭了错误报告，当有错误发生时，错误记录也不会停止。</p>
 
+
 
+<p>不像大多数系统, CodeIgniter的错误报告函数是一个简单的程序接口，可以在整个应用程序里使用。 不用考虑类或者是函数的范围，这种办法可以直接触发错误通知。</p>
 
+
 
+<p>可以使用以下函数来产生错误消息:</p>
 
+
 
+<h2>show_error('<var>消息</var>' [, int <var>$status_code</var> = 500 ] [, string <var>$heading</var> = 'An Error Was Encountered'])</h2>
 
+<p>这个函数将会使用以下错误模版来显示错误消息:</p>
 
+<p><dfn>application/errors/</dfn><kbd>error_general.php</kbd></p>
 
+<p>可选参数 $status_code 决定在显示错误的同时将会发送哪种 HTTP 状态代码。</p>
 
+<p>可选参数 $heading 决定错误模版h1标签内容。</p>
 
+<h2>show_404('<var>页面</var>' [, '<var>log_error</var>'])</h2>
 
+<p>这个函数将会使用以下错误模版来显示 404 错误信息:</p>
 
+<p><dfn>application/errors/</dfn><kbd>error_404.php</kbd></p>
 
+
 
+<p>传递给该函数的字符串代表的是找不到的文件路径。注意CodeIgniter会在找不到目标控制器情况下，自动显示404消息。</p>
 
+
 
+<p>CodeIgniter自动记录任何 show_404() 函数调用。设置第二个可选的参数为FALSE将跳过记录</p>
 
+
 
+<h2>log_message('<var>级别</var>', '<samp>消息</samp>')</h2>
 
+
 
+<p>这个函数可以让你将消息写入记录文件中。你必须在第一个参数中选择三个“级别“中的任何一个, 指明它是那一类消息(调试 debug, 错误 error, 信息info)。 第二个参数是消息本身。  例如:</p>
 
+
 
+<code>
 
+if ($some_var == "")<br />
 
+&#123;<br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;log_message('error', 'Some variable did not contain a value.');<br />
 
+&#125;<br />
 
+else<br />
 
+&#123;<br />
 
+
 
+&nbsp;&nbsp;&nbsp;&nbsp;log_message('debug', 'Some variable was correctly set');<br />
 
+&#125;<br />
 
+<br />
 
+log_message('info', 'The purpose of some variable is to provide some value.');<br />
 
+</code>
 
+
 
+<p>有三种不同类型的消息:</p>
 
+
 
+<ol>
 
+<li>错误类型的消息。  这种是真正的错误消息. 例如PHP错误或者用户错误。</li>
 
+<li>调试类型的消息。  这种是用来帮助调试的消息。 例如， 如果当一个类被初始化时，你可以将这个初始化记录下来，然后用于调试。</li>
 
+<li>信息类型的消息。  这种是最低优先级别的消息，它只是简单的提供了关于运行的一些信息。 CodeIgniter 不会自动产生任何信息类型的消息，但是你可能会在你的程序里使用它。</li>
 
+</ol>
 
+
 
+
 
+<p class="important"><strong>注意:</strong> 确保"logs" 文件夹是可写的,才能准确地将消息写入记录文件中。此外, 你必须设置<dfn>application/config/config.php</dfn>文件中的"threshold"设定，通过设置“threshold“，你可以只记录错误类型的消息，而不用记录其他两种。如果你将“threshold“设为0，记录就会被禁止。</p><p>&nbsp;</p>

+<h1>辅助函数</h1>
 
+
 
+<p>辅助函数，顾名思义，是帮助我们完成特定任务的函数。每个辅助函数文件仅仅是一些函数的集合。例如，<dfn>URL Helpers</dfn> 可以帮助我们创建链接，<dfn>Form Helpers</dfn> 可以帮助我们创建表单，<dfn>Text Helpers</dfn> 提供一系列的格式化输出方式，<dfn>Cookie Helpers</dfn> 能帮助我们设置和读取COOKIE， <dfn>File Helpers</dfn> 能帮助我们处理文件，等等。</p>
 
+
 
+<p>跟其他部分不同的是，辅助函数不是用类的方式来实现的。它们仅仅是一些简单的过程处理函数。
 
+每个辅助函数处理一个特定的任务，并且不必依靠其他函数。</p>
 
+
 
+<p>CodeIgniter 默认是没有载入辅助函数文件的，所以如果你想用辅助函数，就必须先载入它。
 
+一旦被载入，辅助函数将全局可用(globally available)，你可以在 <a href="controllers.html">controller</a> 和 <a href="views.html">views</a> 中使用它们。</p>
 
+
 
+<p>辅助函数文件一般保存在 <dfn>system/helpers</dfn> 或 <dfn>application/helpers</dfn> 文件夹中。CodeIgniter 将会先在 <dfn>application/helpers</dfn> 寻找对应的辅助函数文件，
 
+如果目录不存在或者目录下没有对应的辅助函数文件，CI 才会载入 <dfn>system/helpers</dfn> 下的辅助函数文件。</p>
 
+
 
+
 
+<h2>载入辅助函数</h2>
 
+
 
+<p>载入辅助函数是非常简单的:</p>
 
+
 
+<code>$this-&gt;load-&gt;helper('<var>name</var>');</code>
 
+
 
+<p><var>name</var> 是辅助函数文件的名字(不带.php后缀 和"helper" 部分)。</p>
 
+
 
+<p>例如，要载入文件名为<var>url_helper.php</var>的<dfn>URL Helper</dfn>，你将会用到下面的语句：</p>
 
+
 
+<code>$this-&gt;load-&gt;helper('<var>url</var>');</code>
 
+
 
+<p>辅助函数可以在你的控制器(controller)的任何地方被载入，甚至可以在视图(View)文件中被载入(我们并不建议你这么做)。
 
+请在使用辅助函数之前载入他们。你可以在你的控制器构造函数中载入它们，以便辅助函数能自动在其他函数之前被载入。你也可以在要用到辅助函数的地方当场载入。</p>
 
+
 
+<p class="important">注意: 辅助函数载入函数并不返回值，所以不要尝试将它付给一个变量，直接像这样用就可以了。</p>
 
+
 
+
 
+<h2>载入多个辅助函数</h2>
 
+
 
+<p>如果你想一次载入多个辅助函数，你可以这样做:</p>
 
+
 
+<code>$this-&gt;load-&gt;helper( <samp>array(</samp>'<var>helper1</var>', '<var>helper2</var>', '<var>helper3</var>'<samp>)</samp> );</code>
 
+
 
+<h2>自动载入辅助函数</h2>
 
+
 
+<p>如果你想要的话，CodeIgniter可以自动为你载入辅助函数。你可以通过打开 <var>application/config/autoload.php</var> ，并往自动载入数组(autoload array)中增加辅助函数来实现。</p>
 
+
 
+
 
+<h2>使用辅助函数</h2>
 
+
 
+<p>一旦你载入了想要用到辅助函数文件，你就可以用标准的函数调用方法来使用里面的函数。</p>
 
+
 
+<p>例如，要使用<dfn>anchor()</dfn> 函数来建立一个链接，在视图(View)文件里面你可以这样做:</p>
 
+
 
+<code>&lt;?php echo anchor('blog/comments', 'Click Here');?&gt;</code>
 
+
 
+<p>"Click Here" 是链接的名字，"blog/comments" 是链接的URI。</p>
 
+<p>注意：辅助函数中的函数名最好做好命名规范，如果同时加载多个辅助函数文件，且其中有名称相同的函数，会导致 CI 出现空白页问题（也就是 PHP 语法错误）。</p>
 
+
 
+<h2>“扩展”辅助函数</h2>
 
+
 
+<p>你如果想 "扩展"一个原有的 Helpers，可以在你的 <dfn>application/helpers/</dfn> 目录下创建一个新的helper，新的helper的名字是在被“扩展”的Helper的名字开头多加一个 <kbd>MY_</kbd> (这是可以配置的.  见下.).</p>
 
+
 
+<p>如果你想做的只是在原有的helper中添加一些新的功能，比如，添加一两个新的方法，或者是修改一个方法；就不值得重写自己的helper。在这种情况下，最好是“扩展”已有的helper。“扩展”一词用在这里不是很恰当，因为Helper的方法是过程式的(procedural) 和离散(discrete)的，在传统的语言环境中无法被“扩展”，不过在CodeIgniter中，你可以添加或修改helper的方法。
 
+
 
+</p>
 
+
 
+<p>例如，扩展一个本地已有的 <kbd>Array Helper</kbd> 你应该建立一个文件： <dfn>application/helpers/</dfn><kbd>MY_array_helper.php</kbd>, 并添加或重写（override）其中的一些方法:</p>
 
+
 
+<code>
 
+// any_in_array() is not in the Array Helper, so it defines a new function<br />
 
+function any_in_array($needle, $haystack)<br />
 
+&#123;<br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;$needle = (is_array($needle)) ? $needle : array($needle);<br />
 
+ <br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;foreach ($needle as $item)<br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;&#123;<br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;if (in_array($item, $haystack))<br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&#123;<br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;return TRUE;<br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&#125;<br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&#125;<br />
 
+ <br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;return FALSE;<br />
 
+&#125;<br />
 
+<br />
 
+// random_element() is included in Array Helper, so it overrides the native function<br />
 
+function random_element($array)<br />
 
+&#123;<br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;shuffle($array);<br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;return array_pop($array);<br />
 
+&#125;<br />
 
+</code>
 
+
 
+<h3>设定你自己的前缀（Prefix）</h3>
 
+
 
+<p>用于"扩展" helper 而加上前缀的文件同样也是对库和核心类的扩展.为了设置你自定义的前缀,请打开 <dfn>application/config/config.php</dfn> 文件,然后找到如下的条目:</p>
 
+
 
+<code>$config['subclass_prefix'] = 'MY_';</code>
 
+
 
+<p>请注意：由于所有CodeIgniter自带的库都被冠以 <kbd>CI_</kbd> 这样的前缀命名,所以请不要使用<kbd>CI_</kbd>来自定义前缀.</p>
 
+
 
+<h2>现在可以做什么?</h2>
 
+
 
+<p>在<a href="../toc.html">目录</a>里面有所有辅助函数的列表，你可以打开每个文件看看他们都能做些什么。</p>
 
+<p>不过目前还没有想到更好的方法让我们如何记住这些辅助函数！要不编辑个快速查询手册？？如果你有更好的方法请告诉我！</p><p>&nbsp;</p>

+<h1>钩子 - 扩展框架的核心</h1>
 
+<p>CodeIgniter 的钩子功能使得您可以在不修改系统核心文件的基础上来改变或增加系统的核心运行功能。 当 CodeIgniter 运行后，它会产生出一个特殊的进程，这个进程在 <a href="../overview/appflow.html">项目流程</a> 页面中有说明。 当然，您可以自定义一些动作来替代程序运行过程中的某些阶段。例如，您可以在控制器刚刚载入前或刚刚载入后来运行特定的脚本，或者在其他时刻来触发您的脚本。</p>
 
+<h2>启用钩子</h2>
 
+<p>钩子功能可以在全局范围内打开或关闭，您可以在 <kbd>application/config/config.php</kbd> 文件中设定:</p>
 
+<p><code>$config['enable_hooks'] = TRUE;</code></p>
 
+<h2>定义钩子</h2>
 
+<p>钩子是在 <dfn>application/config/hooks.php</dfn> 文件中定义的。 每个钩子可以用以下格式的数组来定义:</p>
 
+<p><code>$hook['pre_controller'] = array(<br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'class'&nbsp;&nbsp;&nbsp;&nbsp;=&gt; 'MyClass',<br />

+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'params'&nbsp;&nbsp;&nbsp;=&gt; array('beer', 'wine', 'snacks')<br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;);</code></p>
 
+<p><strong>说明：</strong><br />
 
+数组的索引与你使用的指定挂钩点名字相关.上面的例子中挂钩点是<kbd>pre_controller</kbd>. 挂钩点参数列表如下所示. 以下各项将定义在你的相关钩子数组里：</p>
 
+<ul>
 
+    <li><strong>class</strong>&nbsp; 你希望调用的类名.如果你更喜欢使用过程函数代替类的话,此项保留为空.</li>
 
+    <li><strong>function</strong>&nbsp; 你希望调用的函数名.</li>
 
+    <li><strong>filename</strong>&nbsp; 包含有你的类/函数的文件名.</li>
 
+    <li><strong>filepath</strong>&nbsp; 包含你的脚本的目录名. 注意: 你的脚本放在 <kbd>application</kbd> 文件夹下的目录里, 这样 filepath就以那个文件夹(application)为基准. 例如, 如果你的脚本放在<dfn>application/hooks</dfn>下, 你可以把<samp>hooks</samp> 作为你的filepath. 如果你的脚本放在<dfn>application/hooks/utilities</dfn>下你可以把 <samp>hooks/utilities</samp>作为filepath. 注意后面没有"/".如果不放在根目录下可以根据相对路径的配置，来完成调用。这样就可以完成，多个应用共享一个钩子。</li>
 
+    <li><strong>params</strong>&nbsp; 你希望传递给脚本的任何参数. 此项是可选的.</li>
 
+</ul>
 
+<h2>同一挂钩点的多次引用</h2>
 
+<p>如果你想在同一个挂钩点引用多个脚本,最简单的方式就是把你的数组定义成二维的,像这样:</p>
 
+<p><code>$hook['pre_controller']<kbd>[]</kbd> = array(<br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'class'&nbsp;&nbsp;&nbsp;&nbsp;=&gt; 'MyClass',<br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'function' =&gt; 'Myfunction',<br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'filename' =&gt; 'Myclass.php',<br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'filepath' =&gt; 'hooks',<br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'params'&nbsp;&nbsp;&nbsp;=&gt; array('beer', 'wine', 'snacks')<br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;);<br />
 
+<br />
 
+$hook['pre_controller']<kbd>[]</kbd> = array(<br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'class'&nbsp;&nbsp;&nbsp;&nbsp;=&gt; 'MyOtherClass',<br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'function' =&gt; 'MyOtherfunction',<br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'filename' =&gt; 'Myotherclass.php',<br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'filepath' =&gt; 'hooks',<br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'params'&nbsp;&nbsp;&nbsp;=&gt; array('red', 'yellow', 'blue')<br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;);</code></p>
 
+<p>注意在每个数组索引后面的中括号:</p>
 
+<p><code>$hook['pre_controller']<kbd>[]</kbd></code></p>
 
+<p>这允许你的多个脚本拥有相同的挂钩点。你定义数组的顺序将是程序执行的顺序.</p>
 
+<h2>挂勾点</h2>
 
+<p>以下是一组可用的挂钩点.</p>
 
+<ul>
 
+    <li><strong>pre_system</strong><br />
 
+    系统执行的早期调用.仅仅在benchmark 和 hooks&nbsp;类&nbsp;加载完毕的时候. 没有执行路由或者其它的过程.</li>
 
+    <li><strong>pre_controller</strong><br />
 
+    在调用你的任何控制器之前调用.此时所用的基础类,路由选择和安全性检查都已完成.</li>
 
+    <li><strong>post_controller_constructor</strong><br />
 
+    在你的控制器实例化之后,任何方法调用之前调用.</li>
 
+    <li><strong>post_controller</strong><br />
 
+    在你的控制器完全运行之后调用.</li>
 
+    <li><strong>display_override</strong><br />
 
+    覆盖<dfn>_display()</dfn>函数, 用来在系统执行末尾向web浏览器发送最终页面.这允许你用自己的方法来显示.注意，你需要通过 <dfn>$this-&gt;CI =&amp; get_instance()</dfn> 引用 CI 超级对象，然后这样的最终数据可以通过调用 <dfn>$this-&gt;CI-&gt;output-&gt;get_output()</dfn> 来获得。</li>
 
+    <li><strong>cache_override</strong><br />
 
+    可以让你调用自己的函数来取代output类中的<dfn>_display_cache()</dfn> 函数.这可以让你使用自己的缓存显示方法</li>
 
+    <li><strong>post_system</strong><br />
 
+    在最终渲染的页面发送到浏览器之后,浏览器接收完最终数据的系统执行末尾调用</li>
 
+</ul><p>&nbsp;</p>

+<p>所有的类库文件存放在<dfn>system/libraries</dfn> 文件夹。大多数情况下你需要预先在<a href="controllers.html">controller</a>中初始化后才能使用它们:</p>
 
+<code>$this-&gt;load-&gt;library('<var>class name</var>'); </code>
 
+<p><var>class name</var>是你想要使用的类名。例如，要载入“表单验证类”，你可以这样做：</p>
 
+<p><code>$this-&gt;load-&gt;library('<var>form_validation</var>'); </code></p>
 
+<p>一旦类库被载入，你就可以按照用户手册中的方法来使用它们。</p>
 
+
 
+<p>此外，多个类库可以通过传递包含类库的数组一次加载。</p>
 
+
 
+<code>$this-&gt;load-&gt;library(array('<var>email</var>', '<var>table</var>'));</code>

+<h1>管理你的应用程序</h1>
 
+
 
+<p>默认情况下，你会将应用程序放入<dfn>application/</dfn>中，并且可能用 CodeIgniter 只管理这一个应用程序。当然，多个应用程序共享一个 CodeIgniter， 甚至对 <dfn>application</dfn> 文件夹进行重命名或更换路径也是可行的。</p>
 
+
 
+<h2>对应用程序文件夹重命名</h2>
 
+
 
+<p>如果你要对 <dfn>application</dfn> 进行重命名， 你需要打开 <kbd>index.php</kbd> 文件，对变量 <samp>$application_folder</samp> 进行更改:</p>
 
+
 
+<code>$application_folder = "application";</code>
 
+
 
+<h2>更改你的应用程序的文件夹路径</h2>
 
+
 
+<p>你可以将 <dfn>application</dfn>文件夹从<kbd>system</kbd> 文件夹中挪放到服务器的其他的位置。但是你还要更改 <kbd>index.php</kbd> 文件里将<samp>$application_folder</samp>变量设置为<em>服务器的全路径</em>。</p>
 
+
 
+
 
+<code>$application_folder = "/Path/to/your/application";</code>
 
+
 
+
 
+<h2>在一个 CodeIgniter 下运行多个应用程序</h2>
 
+
 
+<p>如果你想要多个应用程序共享同一个 CodeIgniter， 你要将 <kbd>application</kbd> 下所有的文件夹放在不同的应用程序的文件夹内。</p>
 
+
 
+<p>例如，你要建立两个应用程序 "foo" 和 "bar",你的应用程序文件夹的结构可能会像下面的这样:</p>
 
+
 
+<code>applications/<var>foo</var>/<br />
 
+applications/<var>foo</var>/config/<br />
 
+applications/<var>foo</var>/controllers/<br />
 
+applications/<var>foo</var>/errors/<br />
 
+
 
+applications/<var>foo</var>/libraries/<br />
 
+applications/<var>foo</var>/models/<br />
 
+applications/<var>foo</var>/views/<br />
 
+applications/<samp>bar</samp>/<br />
 
+applications/<samp>bar</samp>/config/<br />
 
+
 
+applications/<samp>bar</samp>/controllers/<br />
 
+applications/<samp>bar</samp>/errors/<br />
 
+applications/<samp>bar</samp>/libraries/<br />
 
+applications/<samp>bar</samp>/models/<br />
 
+applications/<samp>bar</samp>/views/</code>
 
+
 
+
 
+<p>要选择使用某个应用程序，你需要打开主 <kbd>index.php</kbd> 文件，并且设置 <dfn>$application_folder</dfn> 变量为目标路径。例如，通过如下设置，就可以选择使用 "foo" 应用程序:</p>
 
+
 
+<code>$application_folder = "applications/foo";</code>
 
+
 
+<p class="important"><strong>注意:</strong>&nbsp; 每一个应用程序都会需要它自己的<dfn>index.php</dfn>文件来调用他的目标程序。你可以随意对 index.php 文件进行命名。</p><p>&nbsp;</p>

+<h2><a name="what"></a>什么是模型?</h2>
 
+
 
+<p>模型是专门用来和数据库打交道的PHP类。例如，假设你想用CodeIgniter来做一个Blog。你可以写一个模型类，里面包含插入、更新、删除Blog数据的方法。下面的例子将向你展示一个普通的模型类:</p>
 
+
 
+<code>
 
+class&nbsp;Blogmodel&nbsp;extends&nbsp;CI_Model&nbsp;&#123;<br />
 
+<br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;var $title&nbsp;&nbsp; = '';<br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;var $content = '';<br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;var $date&nbsp;&nbsp;&nbsp; = '';<br />
 
+<br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;function&nbsp;__construct()<br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;&#123;<br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;parent::__construct();<br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;&#125;<br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;<br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;function&nbsp;get_last_ten_entries()<br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;&#123;<br />
 
+
 
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;$query = $this-&gt;db-&gt;get('entries', 10);<br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;return $query-&gt;result();<br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;&#125;<br />
 
+<br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;function&nbsp;insert_entry()<br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;&#123;<br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;$this-&gt;title&nbsp;&nbsp; = $_POST['title']; // 请阅读下方的备注<br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;$this-&gt;content = $_POST['content'];<br />
 
+
 
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;$this-&gt;date&nbsp;&nbsp;&nbsp; = time();<br />
 
+<br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;$this-&gt;db-&gt;insert('entries',&nbsp;$this);<br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;&#125;<br />
 
+<br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;function&nbsp;update_entry()<br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;&#123;<br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;$this-&gt;title&nbsp;&nbsp; = $_POST['title'];<br />
 
+
 
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;$this-&gt;content = $_POST['content'];<br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;$this-&gt;date&nbsp;&nbsp;&nbsp; = time();<br />
 
+<br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;$this-&gt;db-&gt;update('entries',&nbsp;$this, array('id' => $_POST['id']));<br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;&#125;<br />
 
+<br />
 
+&#125;</code>
 
+
 
+<p>注意: 上面用到的函数是 <a href="../database/active_record.html">Active Record</a> 数据库函数.</p>
 
+
 
+<p class="important"><strong>备注:</strong> 为了简单一点，我们直接使用了$_POST。不过，这不太好，平时我们应该使用 <a href="../libraries/input.html">输入类</a>：$this-&gt;input-&gt;post('title')</p>
 
+
 
+
 
+<h2><a name="anatomy"></a>剖析模型</h2>
 
+
 
+<p>模型类文件存放在 <dfn>application/models/</dfn> 文件夹。 如果你愿意，可以在里面建立子文件夹。</p>
 
+
 
+<p>最基本的模型类必须像这样:</p>
 
+
 
+
 
+<code>
 
+class&nbsp;<var>Model_name</var>&nbsp;extends&nbsp;CI_Model&nbsp;&#123;<br />
 
+<br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;function&nbsp;<var>__construct</var>()<br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;&#123;<br />
 
+
 
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;parent::__construct();<br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;&#125;<br />
 
+&#125;</code>
 
+
 
+<p><var>Model_name</var> 是模型类的名字。  类名的首字母<strong>必须</strong>大写，其他字母小写。
 
+并且确保你的类继承了基本模型类(Base Model Class)。</p>
 
+
 
+<p>文件名应该是模型类名的小写版。比如，如果你的类是:</p>
 
+
 
+<code>
 
+class&nbsp;<var>User_model</var>&nbsp;extends&nbsp;CI_Model&nbsp;&#123;<br />
 
+<br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;function&nbsp;<var>__construct</var>()<br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;&#123;<br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;parent::__construct();<br />
 
+
 
+&nbsp;&nbsp;&nbsp;&nbsp;&#125;<br />
 
+&#125;</code>
 
+
 
+<p>类的文件名应该是：</p>
 
+
 
+<code>application/models/<var>user_model.php</var></code>
 
+
 
+
 
+<h2><a name="loading"></a>载入模型</h2>
 
+
 
+<p>模型可以在 <a href="controllers.html">控制器</a> 中被引用。
 
+就像这样:</p>
 
+
 
+<code>$this-&gt;load-&gt;model('<var>Model_name</var>');</code>
 
+
 
+<p>如果模型文件在子文件夹下，引用的时候要带上相对路径名。例如：如果你有一个模型 <dfn>application/models/blog/queries.php</dfn>。
 
+下面的代码可以引用它:</p>
 
+
 
+<code>$this-&gt;load-&gt;model('<var>blog/queries</var>');</code>
 
+
 
+
 
+<p>模型一旦被载入，你就能通过下面的方法使用它:</p>
 
+
 
+<code>
 
+$this-&gt;load-&gt;model('<var>Model_name</var>');<br />
 
+<br />
 
+$this-&gt;<var>Model_name</var>-&gt;function();
 
+</code>
 
+
 
+<p>在默认的情况下模型名称就直接被引入作为对象名，就如上面所示。当然，如果你愿意，可以起个更好记的对象名！那么，可以在加载模型函数中指定第二个参数来设定，例如：</p>
 
+
 
+<code>
 
+$this-&gt;load-&gt;model('<var>Model_name</var>', '<kbd>fubar</kbd>');<br />
 
+<br />
 
+$this-&gt;<kbd>fubar</kbd>-&gt;function();
 
+</code>
 
+
 
+<p>这里有个控制器的例子，加载一个模型，然后通过视图显示出来</p>
 
+
 
+
 
+
 
+<code>
 
+class&nbsp;Blog_controller&nbsp;extends&nbsp;CI_Controller&nbsp;&#123;<br />
 
+<br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;function&nbsp;blog()<br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;&#123;<br />
 
+
 
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;$this-&gt;load-&gt;model('Blog');<br />
 
+<br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;$data['query'] = $this-&gt;Blog-&gt;get_last_ten_entries();<br /><br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;$this-&gt;load-&gt;view('blog', $data);<br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;&#125;<br />
 
+&#125;</code>
 
+
 
+<h2><a name="auto_load_model" id="auto_load_model"></a>自动载入模型</h2>
 
+<p>如果您需要一个在整个项目中都起作用的特定模型，您可以让 CodeIgniter 在初始化时自动装载它。实现的方法是打开 application/config/autoload.php 文件，然后在自动装载数组中添加上这个模型。</p>
 
+<p class="important"><strong>备注:</strong> 经过测试(以加载一个模型为例)自动加载模型和手动载入模型时，消耗的内存情况是一样的！但是当加载模型越多消耗内存就会越大。自动加载模型是要牺牲内存消耗换取的，所以尽量不要自动加载不必要贯穿全站项目的模型！</p>
 
+</ul>
 
+<h2><a name="conn"></a>连接到数据库</h2>
 
+
 
+<p>当一个模型被载入时，它并不会自动连接数据库。以下方法可以使您连接数据库:</p>
 
+
 
+<ul>
 
+<li>您可以使用标准方法来连接数据库（<a href="../database/connecting.html">说明</a>）, 也可以通过控制器或者您的自定义模型。</li>
 
+<li>您可以把第三个参数设置为TRUE来使模型装载函数自动连接数据库，连接配置可以在您的数据库配置文件中可以定义:</li>
 
+
 
+ <code>$this-&gt;load-&gt;model('<var>Model_name</var>', '', <kbd>TRUE</kbd>);</code> 
+
 
+<li>您可以手动设定第三个参数来载入您的自定义数据库配置:
 
+
 
+  <code>$config['hostname'] = "localhost";<br />
 
+  $config['username'] = "myusername";<br />
 
+  $config['password'] = "mypassword";<br />
 
+  $config['database'] = "mydatabase";<br />
 
+  $config['dbdriver'] = "mysql";<br />
 
+  $config['dbprefix'] = "";<br />
 
+  $config['pconnect'] = FALSE;<br />
 
+  $config['db_debug'] = TRUE;<br />
 
+  <br />
 
+  $this-&gt;load-&gt;model('<var>Model_name</var>', '', <kbd>$config</kbd>);</code></li>
 
+
 
+  <p class="important"><strong>备注:</strong> 经过友好链接测试（也即只连接数据库不涉及查询），自动连接数据库和手动连接数据库时，消耗的内存情况是一样的，我本人的本机测试是0.67M</p>

+<p>该分析器将在页面下方显示基准测试结果，运行过的 SQL 语句，以及 $_POST 数据。这些信息有助于开发过程中的调试和优化。</p>

+
 
+<h2>初始化类</h2>
 
+
 
+<p class="important"><strong>注意:</strong>&nbsp; 此分析器<kbd>无须</kbd>手动初始化.如果已按照下面的方式激活,他将被<a href="../libraries/output.html">输出类</a>自动装载。</p>
 
+
 
+<h2>激活分析器</h2>
 
+
 
+<p>在<a href="controllers.html">控制器</a>中设置以下方法以激活该分析器</p>
 
+<code>$this-&gt;output-&gt;enable_profiler(TRUE);</code>
 
+
 
+<p>分析器激活后将产生一个报告并插入您的页面底部</p>
 
+
 
+<p>使用以下方法禁用该分析器:</p>
 
+<code>$this-&gt;output-&gt;enable_profiler(FALSE);</code>
 
+
 
+<h2>设定基准点</h2>
 
+
 
+<p>为了让该分析器编译和显示你的测试数据，你必须使用特定的语法命名基准点。</p>
 
+
 
+<p>请在<a href="../libraries/benchmark.html">基准测试类</a>部分阅读关于设置基准点的资料。</p>
 
+
 
+<h2>启用和禁用分析数据中的字段</h2>
 
+
 
+<p>分析数据中的每个字段可通过设置相应的控制变量<var>TRUE</var> or <var>FALSE</var>来启用和禁用. 其中的一个方法是：你可以在<dfn>application/config/profiler.php</dfn> 配置文件里设置整个程序的全局默认值.</p>
 
+
 
+  <code>$config['config']&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;= FALSE;<br />
 
+  $config['queries']&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;= FALSE;<br /></code>
 
+
 
+  <p>另一种方法是：你可以在控制器中通过调用<kbd>set_profiler_sections()</kbd> 来覆盖全局设置和默认设置，详细可见： <a href="../libraries/output.html">Output class</a>:</p>
 
+
 
+  <code>$sections = array(<br />
 
+  &nbsp;&nbsp;&nbsp;&nbsp;'config' &nbsp;=> TRUE,<br />

+<p>为了便于编程，CodeIgniter使用了一系列的函数和名称来完成操作。所以，有些名称不能被程序员使用。下面是不能被程序员使用的保留字列表。</p>
 
+
 
+<h3>控制器名称</h3>
 
+<p>因为你的控制器类将继承主程序控制器，所以你的函数命名一定不能和主程序控制器类中的函数名相同，否则你的局部函数将会覆盖他们。下面列出了已经保留的名称，请不要将你的控制器命名为这些：</p>
 
+<ul>
 
+ <li>Controller</li>
 
+ <li>CI_Base</li>
 
+ <li>_ci_initialize</li>

+<h1>URI 路由</h1>
 
+<p>一般来说，URI字符串有着和它唯一对应的控制器(controller)类/方法。URI的各个部分是如下模式（pattern）：</p>
 
+
 
+<code>example.com/<dfn>class</dfn>/<samp>function</samp>/<var>id</var>/</code>
 
+
 
+<p>然而在一些例子中,你也许想重定向这种关系来调用一个不同的类/方法(class/function),而不是与URL一一对应(的调用).</p>
 
+
 
+<p>例如，你可能想使你的URL采用这种原型（prototype）：</p>
 
+
 
+
 
+<p>
 
+example.com/product/1/<br />
 
+example.com/product/2/<br />
 
+example.com/product/3/<br />
 
+example.com/product/4/
 
+</p>
 
+
 
+<p>一般情况下，URL的第二个部分表示方法名，不过在上面的例子中，它表示一个产品的ID。CodeIgniter可以实现这个功能，让用户可以重新定向(remap)URI处理程序.</p>
 
+
 
+<h2>设定你自己的路由规则</h2>
 
+
 
+<p>路由规则定义在<var>application/config/routes.php</var> 文件中.  在此文件中，你可以看到一个名为 <dfn>$route</dfn>的数组，它可以让你定义你自己的路由规则。  定义可以用两种方式： <dfn>通配符(wildcards)</dfn> 或者 <dfn>正则表达式(Regular Expressions)</dfn></p>
 
+
 
+<h2>通配符</h2>
 
+
 
+<p>一个典型的通配符路由看起来是这样的：</p>
 
+
 
+<code>$route['product/(:num)'] = "catalog/product_lookup";</code>
 
+
 
+<p>在一个路由中,数组的键包含着被匹配的URI,而数组的值包含着路由将被重定向的目的地.在上面的例子中,如果单词“product”出现在URL的第一个部分中，而且数字(:num)出现在URI的第二个部分中,"catalog"类和"product_lookup"方法将被替代使用(即将被重定向).</p>
 
+
 
+<p>你可以匹配文字的值或者使用以下两种通配符类型:</p>
 
+
 
+<p><strong>:num</strong> 将匹配一个只包含有数字的segment(段).<br />
 
+    <strong>:any</strong> 将匹配任何字符(可以是多个segment段).<strong>可以匹配多个值，</strong>如：<br />
 
+    <code>$route['product/(:any)'] = "catalog/product_lookup/$1/$2/$3/$4/$5";&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;//将整条url上的每一个参数全部传递给catalog控制器下的 product_lookup方法。</code>
 
+</p>
 
+
 
+<p class="important"><strong>注意:</strong> 路由将会按照定义的顺序来运行.高层的路由总是优先于低层的路由.</p>
 
+
 
+
 
+<h2>例子</h2>
 
+
 
+<p>下面是一些简单的例子:</p>
 
+
 
+<code>$route['journals'] = "blogs";</code>
 
+<p>如果URL的第一个分段（类名）是关键字"journals"，那么将会重定向到"blogs"类中处理.</p>
 
+
 
+<code>$route['blog/joe'] = "blogs/users/34";</code>
 
+<p>如果URL的前两个分段是"blog"和"joe"，那么将会重定向到"blogs"类的"users"方法中处理.并且将ID"34"设为参数.</p>
 
+
 
+
 
+<code>$route['product/(:any)'] = "catalog/product_lookup";</code>
 
+<p>当"product"作为URL中第一个分段时, 无论第二分段是什么都将被重定向到"catalog"类的"product_lookup"方法.</p>
 
+
 
+<code>$route['product/(:num)'] = "catalog/product_lookup_by_id/$1";</code>
 
+<p>当“product”作为 URL 中第一个分段时，如果第二分段是数字，则将被重定向到“catalog”类，并传递所匹配的内容到“product_lookup_by_id”方法中。</p>
 
+
 
+<p class="important"><strong>重要提示:</strong> 不要在前面或后面加"/".</p>
 
+
 
+<h2>正则表达式</h2>
 
+
 
+<p>如果你喜欢可以使用正则表达式来自定义你的路由规则.  任何有效的正则表达式都是被允许的, 甚至逆向引用.</p>
 
+
 
+<p class="important"><strong>注意:</strong>&nbsp; 如果你使用逆向引用请将双反斜线语法替换为美元符语法（\\1 替换为 $1).</p>
 
+
 
+<p>一个典型的正则表达式看起来像下面的样子:</p>
 
+
 
+<code>$route['products/([a-z]+)/(\d+)'] = "$1/id_$2";</code>
 
+
 
+<p>上例中, 类似于 <dfn>products/shirts/123</dfn> 的URI 将换成调用 <dfn>shirts</dfn> 控制器类的 <dfn>id_123</dfn> 方法.</p>
 
+
 
+<p>你也可以混合使用通配符与正则表达式.</p>
 
+
 
+<h2>系统保留的路由</h2>
 
+
 
+<p>系统会保留两个路由：</p>
 
+
 
+<p>第一个为系统默认的路由：</p>
 
+
 
+<code>$route['default_controller'] = 'welcome';</code>
 
+
 
+<p>这个路由表明了当URI中不包含要访问的类和控制器信息的（即只访问根目录的情况，如http://localhost/ci）将要加载哪个控制器。上例中,系统将加载 "welcome" 这个类（控制器）。你应该保证设置一个默认路由，不然你的首页将会显示 404 错误。</p>
 
+
 
+<p>第二个为404页面的路由：</p>
 
+
 
+<code>$route['404_override'] = '';</code>
 
+
 
+<p>这个路由标识了如果请求的控制器无法访问的时候将加载哪个控制器。它相当于覆盖了默认的404错误页面（即提供了自己定义404页面的功能）。但它不会影响<samp>show_404()</samp>这个方法，这个方法依然会加载默认的位于<var>application/errors/error_404.php</var>的<dfn>error_404.php</dfn>页面。</p>
 
+
 
+<p class="important"><strong>重要:</strong> 保留的路由应该在所有通配符或正则表达式路由之前定义。</p><p>&nbsp;</p>

+<h1>安全</h1>
 
+
 
+<p>本页描述了一些关于 Web 安全的“最佳实践”，并详细说明了 CodeIgniter 的内部安全特性。</p>
 
+
 
+
 
+<h2>URI 安全</h2>
 
+
 
+<p>CodeIgniter 严格限制 URI 中所能包含的字符，以此帮助你设计的程序减少被恶意数据入侵的可能。URI 一般只包含下列内容：
 
+</p>
 
+
 
+<ul>
 
+<li>字母和数字（Alpha-numeric text）</li>
 
+<li>波浪符（Tilde）： ~ </li>
 
+<li>句号（Period）： .</li>
 
+<li>冒号（Colon）： :</li>
 
+<li>下划线（Underscore）： _</li>
 
+<li>破折号（Dash）： -</li>
 
+</ul>
 
+
 
+
 
+<h2>Register_globals</h2>
 
+
 
+<p>系统初始化期间所有的全局变量都被 unset，除了那些在 $_GET、$_POST 和 $_COOKIE 数组中的数据。实际上 unsetting 实例程序的作用与register_globals = off 相同。</p>
 
+
 
+<a name="error_reporting"></a>
 
+<h2>error_reporting</h2>
 
+
 
+<p>
 
+  在生产环境中，往往有必要通过设置内部的error_reporting值为0来禁用PHP错误报告。
 
+  这可以防止可能含有敏感信息的原始PHP错误报告输出。
 
+</p>
 
+
 
+<p>
 
+  在 index.php 设置CodeIgniter的 <kbd>ENVIRONMENT</kbd> 常量为 '<kbd>production</kbd>' 
+  将会关闭这些错误(报告)。在开发模式下，推荐设为 '<kbd>development</kbd>'。
 
+  更多关于各环境间区别的信息可以在<a href="environments.html">处理多环境</a>一章找到。
 
+</p>
 
+
 
+
 
+<h2>magic_quotes_runtime</h2>
 
+
 
+<p>在系统初始化期间 magic_quotes_runtime 指令被关闭以便在数据库检索数据时不必去掉反斜线。</p>
 
+
 
+<h1>最佳实践</h1>
 
+
 
+<p>在接收任何数据到你的程序之前，不管是表单提交的 POST 数据、COOKIE 数据、URI 数据、XML-RPC 数据、还是 SERVER 数组中的数据，我们都推荐你实践下面的三个步骤：</p>
 
+
 
+<ol>
 
+
 
+<li>过滤不良数据.</li>
 
+<li>验证数据以确保符合正确的类型, 长度, 大小等. (有时这一步骤也可取代第一步骤)</li>
 
+<li>在提交数据到你的数据库之前将其转换.</li>
 
+
 
+</ol>
 
+
 
+<p>CodeIgniter 提供了下列函数以辅助这个过程:</p>
 
+
 
+<ul>
 
+
 
+<li><h2>XSS 过滤</h2>
 
+
 
+<p>CodeIgniter带有一个跨站脚本过滤器. 这个过滤器会查找那些用通常手段嵌入到你数据中恶意的Javascript,或其它一些试图欺骗cookie类型的或者做其它恶意事情的代码. XSS Filter的详细描述在 <a href="../libraries/security.html">这里</a>.
 
+</p>
 
+</li>
 
+
 
+<li><h2>验证数据</h2>
 
+
 
+<p>CodeIgniter 有一个<a href="../libraries/form_validation.html">表单验证类</a>用来帮助验证、过滤和预处理数据。</p>
 
+</li>
 
+
 
+<li><h2>插入数据库之前转义所有数据</h2>
 
+
 
+<p>不要插入未转义的信息到你的数据库中。要了解更多信息请参阅<a href="../database/queries.html">查询</a>章节。</p>
 
+
 
+</li>
 
+
 
+</ul><p>&nbsp;</p>

+<h1>CodeIgniter URL</h1>
 
+<p>默认情况下，CodeIgniter 中的 URL 被设计成对搜索引擎和人类友好。不同于使用标准&ldquo;查询字符串&rdquo;方法的是，CodeIgniter 使用<strong>基于段</strong>的方法：</p>
 
+<code>example.com/<var>news</var>/<dfn>article</dfn>/<samp>my_article</samp></code>
 
+<p class="important"><strong>注意：</strong>查询字符串形式的 URL 是可选的，分述如下。</p>
 
+<h2>URI 段</h2>
 
+<p>根据模型-视图-控制器模式，在此 URL 段一般以如下形式表示：</p>
 
+<code>example.com/<var>class</var>/<dfn>function</dfn>/<samp>ID</samp></code>
 
+<ol>
 
+    <li>第一段表示调用控制器<strong>类</strong>。</li>
 
+    <li>第二段表示调用类中的<strong>函数</strong>或方法。</li>
 
+    <li>第三及更多的段表示的是传递给控制器的参数，如 ID 或其它各种变量。</li>
 
+</ol>
 
+<p><a href="../libraries/uri.html">URI 类</a>和 <a href="../helpers/url_helper.html">URL 辅助函数</a>中的函数可以使你的 URI 更简单的工作。另外，使用 <a href="routing.html">URI 路由</a>特性可以将你的 URL 重定向，以获得更大的灵活性。</p>
 
+<h2>删除 index.php 文件</h2>
 
+<p>默认情况下，<strong>index.php</strong> 文件将被包含在你的 URL 中：</p>
 
+<code>example.com/<var>index.php</var>/news/article/my_article</code>
 
+<p>你可以很容易的通过 .htaccess 文件来设置一些简单的规则删除它。下面是一个例子，使用&ldquo;negative&rdquo;方法将非指定内容进行重定向：</p>
 
+<p><code>RewriteEngine on<br /><br>
 
+    RewriteCond %&#123;REQUEST_FILENAME&#125; !-f<br>
 
+ RewriteCond %&#123;REQUEST_FILENAME&#125; !-d  &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;//此处有大坑。加上这两句可保证一般css、js文件正常加载。(注意删掉这句注释哦)<br /><br>
 
+RewriteCond $1 !^(index\.php|images|robots\.txt)<br />
 
+RewriteRule ^(.*)$ /index.php/$1 [L]</code></p>
 
+<p class="important"><strong>注意:</strong>如果你的项目不在根目录请把上面这一句改为：<strong>RewriteRule ^(.*)$ index.php/$1 [L]</strong></p>
 
+<p>在上面的例子中，可以实现任何非 index.php、images 和 robots.txt 的 HTTP 请求都被指向 index.php。</p>
 
+<h2>添加 URL 后缀</h2>
 
+<p>通过设置 <dfn>config/config.php</dfn> 文件，你可以为 CodeIgniter 生成的 URL 添加一个指定的文件后缀。举例来说，如果 URL 是这样的：</p>
 
+<code>example.com/index.php/products/view/shoes</code>
 
+<p>你可以随意添加一个后缀，例如 <kbd>.html</kbd>，使其显示为：</p>
 
+<code>example.com/index.php/products/view/shoes.html</code>
 
+<p>(icebird注：英文中由于参数可直接看懂其含义，并未说明应修改哪个参数，在这里应修改$config['url_suffix']这个参数。)</p>
 
+<h2>启用查询字符串</h2>
 
+<p>在一些情况下你需要在 URL 中使用查询字符串：</p>
 
+<code>index.php?c=products&amp;m=view&amp;id=345</code>
 
+<p>CodeIgniter 支持这个功能是可选的，可以在 <dfn>application/config/config.php</dfn> 文件中进行设置。如果你打开 config 文件可以看到如下内容：</p>
 
+<p><code>$config['enable_query_strings'] = FALSE;<br />
 
+  $config['controller_trigger'] = 'c'; //控制器名<br />
 
+  $config['function_trigger'] = 'm'; //方法名<br />
 
+  $config['directory_trigger']='d'; //若控制器在子目录下，URL中需带有这个参数，指定控制器所在子目录名称
 
+
 
+  </code></p>
 
+<p>如果你将 enable_query_strings 更改为 TRUE ，那么这个功能就被激活了。此时，你就可以通过关键字来调用需要的控制器和方法了：</p>
 
+<code>index.php?c=controller&amp;m=method</code>
 
+<p class="important"><strong>请注意：</strong>如果你使用查询字符串，那么就必须使用自己建立的 URL ，而且不能使用URL 辅助函数（或是其他生成 URL 的辅助函数，例如表单辅助函数），因为这些都是根据分段 URL 设计的。</p><p>&nbsp;</p>

+<h1>视图</h1>
 
+<p>简而言之，一个<dfn>视图</dfn>就是一个网页，或是网页的部分，如头部，底部，侧边栏等等。事实上，如果你需要这种层次类型，视图可以很灵活的嵌入到其他视图中。</p>
 
+<p>视图从不直接调用，必须被一个<a href="controllers.html">控制器</a>来调用。记住，在一个 MVC 框架中，控制器扮演着交通警察的角色，那么，他有责任去取回某一特定的视图。如果你还没有阅读过控制器页面的话，你应该事先阅读<a href="controllers.html">控制器</a>页面。</p>
 
+<p>下面使用你在<a href="controllers.html">控制器</a>页面已经创建过的示例控制器,让我们来给他添加个视图。</p>
 
+<h2>创建视图</h2>
 
+<p>使用你的文本编辑器，创建一个名为 <dfn>blogview.php </dfn>的文件，写入以下代码：</p>
 
+<p><textarea cols="50" rows="10" style="width: 100%;" class="textarea">
 
+&lt;html&gt;
 
+&lt;head&gt;
 
+&lt;title&gt;My Blog&lt;/title&gt;
 
+&lt;/head&gt;
 
+&lt;body&gt;
 
+ <h1>Welcome to my Blog!</h1>
 
+&lt;/body&gt;
 
+&lt;/html&gt;
 
+</textarea></p>
 
+<p>然后保存文件到 <dfn>application/views/</dfn>  文件夹。</p>
 
+<h2>载入视图</h2>
 
+<p>你必须使用下面的函数来载入一个视图文件:</p>
 
+<p><code>$this-&gt;load-&gt;view('<var>name</var>');</code></p>
 
+<p>上面的 <var>name</var> 便是你的视图文件的名字。注意：.php 文件的扩展名(后缀名)没有必要专门写出，除非你使用了其他的扩展名。</p>
 
+<p>现在, 打开你先前写的名为  <dfn>blog.php</dfn>  控制器文件,并且使用视图载入函数替换echo段代码:</p>
 
+<p><textarea cols="50" rows="10" style="width: 100%;" class="textarea">&lt;?php
 
+class Blog extends CI_Controller &#123;
 
+
 
+ function index()
 
+ &#123;
 
+  $this-&gt;load-&gt;view('blogview');
 
+ &#125;
 
+&#125;
 
+?&gt;  </textarea></p>
 
+<p>如果你使用先前你用的 URL 浏览你的网站,你将会看到你的新视图. URL 与下面的类似:</p>
 
+<code>example.com/index.php/<var>blog</var>/</code>
 
+
 
+<h2>载入多个视图</h2>
 
+<p>CodeIgniter 能智能的处理多个从控制器发起的视图载入函数调用 $this-&gt;load-&gt;view。如果有多个调用，那么他们将会被合并到一起。例如，你可能希望有一个标题视图、一个菜单视图、一个内容视图、和一个页脚视图。他们看起来应该是这样：</p>
 
+
 
+<p><code>&lt;?php<br />
 
+<br />
 
+class Page extends CI_Controller &#123;<br /><br />
 
+
 
+ &nbsp;&nbsp;&nbsp;function index()<br />
 
+&nbsp;&nbsp;&nbsp;&#123;<br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;$data['page_title'] =  'Your title';<br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;$this-&gt;load-&gt;view('header');<br />
 
+
 
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;$this-&gt;load-&gt;view('menu');<br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;$this-&gt;load-&gt;view('content', $data);<br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;$this-&gt;load-&gt;view('footer');<br />
 
+&nbsp;&nbsp;&nbsp;&#125;<br />
 
+<br />
 
+&#125;<br />
 
+
 
+    ?&gt;</code></p>
 
+<p>在上面的例子中，我们使用了“动态添加数据”，你将在下面看到。</p>
 
+
 
+<h2>用子文件夹存储视图</h2>
 
+<p>如果你想让文件更有组织性,你也可以用子文件夹来存储你的视图文件.. 当你在载入视图时,必须加上子文件夹的名字. 示例如下:</p>
 
+<p><code>$this-&gt;load-&gt;view('<kbd>folder_name</kbd>/<var>file_name</var>');</code></p>
 
+<h2>给视图添加动态数据</h2>
 
+<p>数据通过控制器以一个<strong>数组</strong>或是<strong>对象</strong>的形式传入视图 , 这个数组或对象作为视图载入函数的第二个参数 .下面便是使用数组的示例:</p>
 
+<p><code>$data = array(<br />
 
+               'title' => 'My Title',<br />
 
+               'heading' => 'My Heading',<br />
 
+               'message' => 'My Message'<br />
 
+          );<br />
 
+<br />
 
+$this-&gt;load-&gt;view('blogview', <var>$data</var>);</code></p>
 
+<p>这里是使用对象的示例:</p>
 
+<p><code>$data = new Someclass();<br />
 
+$this-&gt;load-&gt;view('blogview', <var>$data</var>);</code></p>
 
+<p>当我们一次性载入多个视图的时候，你只需在第一个视图传入数据就可以了(header视图显示title,content视图显示message)，比如：</p>
 
+<p><code><br />
 
+&lt;?php<br />
 
+<br />
 
+class Page extends CI_Controller &#123;<br /><br />
 
+
 
+ &nbsp;&nbsp;&nbsp;function index()<br />
 
+&nbsp;&nbsp;&nbsp;&#123;<br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;$data['title'] =  'Your title';<br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;$data['message'] =  'Your message';<br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;$this-&gt;load-&gt;view('header',$data);<br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;$this-&gt;load-&gt;view('content');<br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;$this-&gt;load-&gt;view('footer');<br />
 
+&nbsp;&nbsp;&nbsp;&#125;<br />
 
+<br />
 
+&#125;<br />
 
+
 
+    ?&gt;</code></p>
 
+<p>注意：如果你使用一个对象，那么类变量将转换为数组元素。</p>
 
+<p>好了，让我们用你的控制器试试。打开控制器并添加以下代码：</p>
 
+<p><textarea cols="50" rows="14" style="width: 100%;" class="textarea">&lt;?php
 
+class Blog extends CI_Controller &#123;
 
+
 
+ function index()
 
+ &#123;
 
+  $data['title'] = "My Real Title";
 
+  $data['heading'] = "My Real Heading";
 
+  
+  $this-&gt;load-&gt;view('blogview', $data);
 
+ &#125;
 
+&#125;
 
+?&gt; </textarea></p>
 
+<p>现在，打开你的视图文件，将其中的文本替换成与数组对应的变量：</p>
 
+<p><textarea rows="10" cols="50" style="width: 100%;" class="textarea">
 
+&lt;html&gt;
 
+&lt;head&gt;
 
+&lt;title&gt;&lt;?php echo $title;?&gt;&lt;/title&gt;
 
+&lt;/head&gt;
 
+&lt;body&gt;
 
+ <h1>&lt;?php echo $heading;?&gt;</h1>
 
+&lt;/body&gt;
 
+&lt;/html&gt;
 
+</textarea></p>
 
+<p>然后使用你先前用过的URL载入页面，你将看到变量已经被替换。</p>
 
+
 
+<h2>创建循环</h2>
 
+<p>你传入视图文件的数据，不仅仅局限于简单的变量。你可以传递多维数组。例如：你从数据库里面取出数据就是典型的多维数据。</p>
 
+<p>这里是个简单的示例。添加以下代码到你的控制器：</p>
 
+<p><textarea cols="50" rows="17" style="width: 100%;" class="textarea">&lt;?php
 
+class Blog extends CI_Controller &#123;
 
+
 
+ function index()
 
+ &#123;
 
+  $data['todo_list'] = array('Clean House', 'Call Mom', 'Run Errands');
 
+
 
+  $data['title'] = "My Real Title";
 
+  $data['heading'] = "My Real Heading";
 
+  
+  $this-&gt;load-&gt;view('blogview', $data);
 
+ &#125;
 
+&#125;
 
+?&gt; </textarea></p>
 
+<p>现在打开你的视图文件，创建一个循环：</p>
 
+<textarea class="textarea" style="width:100%" cols="50" rows="24">
 
+&lt;html&gt;
 
+&lt;head&gt;
 
+&lt;title>&lt;?php echo $title;?&gt;&lt;/title>
 
+&lt;/head&gt;
 
+&lt;body&gt;
 
+&lt;h1>&lt;?php echo $heading;?&gt;&lt;/h1>
 
+ 
+<h3>My Todo List</h3> 
+
 
+<ul>
 
+&lt;?php foreach ($todo_list as $item):?&gt;
 
+
 
+&lt;li>&lt;?php echo $item;?&gt;&lt;/li>
 
+
 
+&lt;?php endforeach;?&gt;
 
+</ul>
 
+ 
+&lt;/body&gt;
 
+&lt;/html&gt;
 
+</textarea>
 
+<p><strong>注意:</strong> 上面的例子中我们使用PHP替代语法。如果你对这种语法不熟悉，可以在<a href="alternative_php.html">这里</a>阅读。</p>
 
+
 
+<h2>获取视图内容</h2>
 
+
 
+<p>view函数第三个<strong>可选</strong>参数可以改变函数的行为，让数据作为字符串返回而不是发送到浏览器。如果想用其它方式对数据进一步处理，这样做很有用。如果将view第三个参数设置为<dbd>true</dbd>（布尔）则函数返回数据。view函数缺省行为是 <dbd>false</dbd>,　将数据发送到浏览器。如果想返回数据，记得将它赋到一个变量中：</p>
 
+
 
+<code>$string = $this-&gt;load-&gt;view('<var>myfile</var>', '', <kbd>true</kbd>);</code>
 
+
 
+<p>例子：有些情况下，你并不想直接输出视图，而是仅仅想得到视图的内容以备后用。那么可以参考如下代码。</p>
 
+<p><textarea cols="50" rows="13" style="width: 100%;" class="textarea">&lt;?php
 
+class Blog extends CI_Controller &#123;
 
+
 
+ function index()
 
+ &#123;
 
+  $data['todo_list'] = array('Clean House', 'Call Mom', 'Run Errands');
 
+
 
+  $data['title'] = "My Real Title";
 
+  $data['heading'] = "My Real Heading";
 
+  
+  $buffer = $this-&gt;load-&gt;view('blogview', $data, true);
 
+ &#125;
 
+&#125;
 
+?&gt; </textarea></p>
 
+<p>view方法中的第三个参数表示不输出视图，而只是将结果返回给一个变量。</p><p>&nbsp;</p>

+<h1>数组辅助函数</h1>
 
+<p>数组辅助函数的文件涵盖了一些用于辅助数组操作的函数。</p>
 
+<h2>装载本辅助函数</h2>
 
+<p>本辅助函数的装载通过如下代码完成：</p>
 
+<p><code>$this-&gt;load-&gt;helper('array');</code></p>
 
+<p>可用的函数如下：</p>
 
+<h2>element()</h2>
 
+<p>获取数组中的元素。本函数测试数组的索引是否已设定并含有数值。如果已设有数值则返回该数值，否则返回 FALSE，或任何你设定的默认数值（函数第三个参数）。范例：</p>
 
+<p><code> $array = array('color' =&gt; 'red', 'shape' =&gt; 'round', 'size' =&gt; '');<br />
 
+<br />
 
+// 返回 &quot;red&quot;<br />
 
+echo element('color', $array);<br />
 
+<br />
 
+// 返回 NULL<br />
 
+echo element('size', $array, NULL); </code></p>
 
+<h2>random_element()</h2>
 
+<p>根据提供的数组，随机返回该数组内的一个元素。使用范例：</p>
 
+<p><code>$quotes = array(<br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&quot;I find that the harder I work, the more luck I seem to have. - Thomas Jefferson&quot;,<br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&quot;Don't stay in bed, unless you can make money in bed. - George Burns&quot;,<br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&quot;We didn't lose the game; we just ran out of time. - Vince Lombardi&quot;,<br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&quot;If everything seems under control, you're not going fast enough. - Mario Andretti&quot;,<br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&quot;Reality is merely an illusion, albeit a very persistent one. - Albert Einstein&quot;,<br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&quot;Chance favors the prepared mind - Louis Pasteur&quot;<br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;);<br />
 
+<br />
 
+echo random_element($quotes);</code></p>
 
+
 
+<h2>elements()</h2>
 
+
 
+<p>Lets you fetch a number of items from an array.  The function tests whether each of the array indices is set.  If an index does not exist
 
+it is set to FALSE, or whatever you've specified as the default value via the third parameter.  Example:</p>
 
+
 
+<p><strong>试译：</strong>该函数从一个数组中取得若干元素。该函数测试（传入）数组的每个键值是否在（目标）数组中已定义；如果一个键值不存在，该键值所对应的值将被置为FALSE，或者你可以通过传入的第3个参数来指定默认的值。例如：</p>
 
+
 
+<code>
 
+$array = array(<br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;'color' => 'red',<br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;'shape' => 'round',<br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;'radius' => '10',<br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;'diameter' => '20'<br />
 
+);<br />
 
+<br />
 
+$my_shape = elements(array('color', 'shape', 'height'), $array);<br />
 
+</code>
 
+
 
+<p>The above will return the following array:</p>
 
+
 
+<p><strong>试译：</strong>上面的程序将返回下面的数组：</p>
 
+
 
+<code>
 
+array(<br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;'color' => 'red',<br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;'shape' => 'round',<br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;'height' => FALSE<br />
 
+);
 
+</code>
 
+
 
+<p>You can set the third parameter to any default value you like:</p>
 
+
 
+<p><strong>试译：</strong>你可以将第3个参数设为任何你想要的默认值：</p>
 
+
 
+<code>
 
+$my_shape = elements(array('color', 'shape', 'height'), $array, NULL);<br />
 
+</code>
 
+
 
+<p>The above will return the following array:</p>
 
+
 
+<p><strong>试译：</strong>上面的程序将返回下面的数组：</p>
 
+
 
+<code>
 
+array(<br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;'color' => 'red',<br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;'shape' => 'round',<br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;'height' => NULL<br />
 
+);
 
+</code>
 
+
 
+<p>This is useful when sending the <kbd>$_POST</kbd> array to one of your Models.  This prevents users from
 
+sending additional POST data to be entered into your tables:</p>
 
+
 
+<p><strong>试译：</strong>这（种方法）在将 <kbd>$_POST</kbd> 数组传入你的模型时非常有用。通过这种方式可以防止用户发送的额外的 POST 数据进入你的数据表：</p>
 
+
 
+<code>
 
+$this-&gt;load-&gt;model('post_model');<br />
 
+<br />
 
+$this-&gt;post_model-&gt;update(elements(array('id', 'title', 'content'), $_POST));
 
+</code>
 
+
 
+<p>This ensures that only the id, title and content fields are sent to be updated.</p>
 
+
 
+<p><strong>试译：</strong>这样保证了只有 id, title 和 content 字段被发送以进行更新。</p><p>&nbsp;</p>

+<h1>CAPTCHA 辅助函数</h1>
 
+
 
+<p>验证码辅助函数用来生成图片验证码</p>
 
+
 
+
 
+<h2>加载辅助函数</h2>
 
+
 
+<p>用下面的代码加载验证码辅助函数:</p>
 
+<code>$this-&gt;load-&gt;helper('captcha');</code>
 
+
 
+<p>可用的函数如下：</p>
 
+
 
+<h2>create_captcha(<var>$data</var>)</h2>
 
+
 
+<p>根据你指定的一系列参数创建验证码图像, 返回值是一个包含此图像数据的数组.</p>
 
+
 
+<code>[array]<br />
 
+(<br />
 
+&nbsp;&nbsp;'image' => IMAGE TAG<br />
 
+
 
+&nbsp;&nbsp;'time'  => TIMESTAMP (毫秒)<br />
 
+&nbsp;&nbsp;'word'  => CAPTCHA WORD<br />
 
+)</code>
 
+
 
+  <p>"image"是实际存在image标记:
 
+<code>&lt;img src=&quot;http://example.com/captcha/12345.jpg&quot; width=&quot;140&quot; height=&quot;50&quot; /&gt;</code></p>
 
+
 
+  <p>这里的"time"是一个毫秒级的时间戳，作为图片文件名（不包含扩展名）. 就像这样:  1139612155.3422</p>
 
+
 
+  <p>"word"是验证码, 如果不提供, 将是一个随机字符串.</p>
 
+
 
+  <h3>使用验证码辅助函数：</h3>
 
+
 
+  <p>加载后你可以向这样产生一个验证码:</p>
 
+
 
+<code>$vals = array(<br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;'word'     => 'Random word',<br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;'img_path'   => './captcha/',<br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;'img_url'   => 'http://example.com/captcha/',<br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;'font_path'   => './path/to/fonts/texb.ttf',<br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;'img_width'   => '150',<br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;'img_height' => 30,<br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;'expiration' => 7200<br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;);<br />
 
+
 
+<br />
 
+$cap = create_captcha($vals);<br />
 
+echo $cap['image'];</code>
 
+
 
+  <ul>
 
+    <li>验证码辅助函数必须需要GD库.</li>
 
+    <li>只有 img_path 和 img_url 参数是必须的.</li>
 
+    <li>如果"word"未提供, 将自动产生一个ASCII字符串.  你也可以使用自己的词库，从里面随机挑选.</li>
 
+
 
+    <li>如果未提供TRUE TYPE字体的路径, 将会使用GD自带的字体.</li>
 
+    <li> "captcha" 目录必须可写(666, or 777)</li>
 
+    <li>"expiration" (秒) 指定了验证码图片的超时删除时间.  默认是2小时.</li>
 
+  </ul>
 
+
 
+  <h3>配合数据库</h3>
 
+
 
+  <p>为了在提交表单时用到验证，你需要将<kbd>create_captcha()</kbd>生成的结果保存到数据库。这样，当用户提交表单时，你就可以验证数据库里是否有此验证码或是否过期。</p>
 
+
 
+  <p>这是一个数据表的例子:</p>
 
+
 
+<code>CREATE TABLE captcha (<br />
 
+&nbsp;captcha_id bigint(13) unsigned NOT NULL auto_increment,<br />
 
+&nbsp;captcha_time int(10) unsigned NOT NULL,<br />
 
+&nbsp;ip_address varchar(16) default '0' NOT NULL,<br />

+&nbsp;PRIMARY KEY `captcha_id` (`captcha_id`),<br />
 
+
 
+&nbsp;KEY `word` (`word`)<br />
 
+);</code>
 
+
 
+  <p>这是一个使用数据库的例子.  一个带验证码的页面显示如下:</p>
 
+
 
+<code>$this-&gt;load-&gt;helper(&#x27;captcha&#x27;);<br />
 
+$vals = array(<br />
 
+
 
+&nbsp;&nbsp;&nbsp;&nbsp;&#x27;img_path&#x27;   =&gt; &#x27;./captcha/&#x27;,<br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;&#x27;img_url&#x27;   =&gt; &#x27;http://example.com/captcha/&#x27;<br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;);<br />
 
+<br />
 
+$cap = create_captcha($vals);<br />
 
+

+&nbsp;&nbsp;&nbsp;&nbsp;&#x27;word&#x27;      =&gt; $cap[&#x27;word&#x27;]<br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;);<br />
 
+<br />
 
+$query = $this-&gt;db-&gt;insert_string(&#x27;captcha&#x27;, $data);<br />

+$this-&gt;db-&gt;query($query);<br />
 
+<br />
 
+echo &#x27;提交下面的验证码:&#x27;;<br />

+echo &#x27;&lt;input type=&quot;text&quot; name=&quot;captcha&quot; value=&quot;&quot; /&gt;&#x27;;</code>
 
+
 
+  <p>然后页面提交后如下处理:</p>
 
+
 
+<code>// 首先删除旧的验证码<br />
 
+$expiration = time()-7200; // 2小时限制<br />
 
+$this-&gt;db-&gt;query(&quot;DELETE FROM captcha WHERE captcha_time &lt; &quot;.$expiration);  <br />
 
+<br />
 
+
 
+// 然后再看是否有验证码存在:<br />
 
+$sql = &quot;SELECT COUNT(*) AS count FROM captcha WHERE word = ? AND ip_address = ? AND captcha_time &gt; ?&quot;;<br />
 
+$binds = array($_POST[&#x27;captcha&#x27;], $this-&gt;input-&gt;ip_address(), $expiration);<br />
 
+$query = $this-&gt;db-&gt;query($sql, $binds);<br />
 
+
 
+$row = $query-&gt;row();<br />
 
+<br />
 
+if ($row-&gt;count == 0)<br />
 
+&#123;<br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;echo &quot;你必须提交图像上显示的验证码&quot;;<br />
 
+&#125;</code><p>&nbsp;</p>

+<h1>Cookie Helper</h1>
 
+
 
+<p>Cookie Helper 中包含了多个cookie辅助函数.</p>
 
+
 
+<h2>装载这个 helper</h2>
 
+
 
+<p>这个 helper 可以通过下面的方法来装载:</p>
 
+
 
+<code>$this-&gt;load-&gt;helper('cookie');</code>
 
+
 
+<p>下面这种方法同样可以:</p>
 
+
 
+<h2>set_cookie()</h2>
 
+
 
+
 
+<p>这个辅助函数给你一种优雅的体验来设置浏览器的cookie。 参考 <a href="../libraries/input.html">Input 类</a>的用途描述， 这个辅助函数可以这样调用 $this-&gt;input-&gt;set_cookie().</p>
 
+
 
+
 
+<h2>get_cookie()</h2>
 
+
 
+<p>这个辅助函数给你一种优雅的体验来获取浏览器的cookie。参考 <a href="../libraries/input.html">Input 类</a>的用途描述, 这个辅助函数可以这样调用：$this-&gt;input-&gt;cookie().</p>
 
+<h2>delete_cookie()</h2>
 
+
 
+<p>可以让你删除一个cookie,除非你设置了一个自定义的路径或者其他变量，否则只要给出cookie的名字就行了:</p>
 
+
 
+<code>delete_cookie("name");</code>
 
+
 
+<p>这个函数与<dfn>set_cookie()</dfn>函数比较像, 除了它没有值和超时参数.  你可以把一个数组作为第一个参数提交，也可以像下面这样，设置独立的参数.</p>
 
+
 
+<code>delete_cookie($name, $domain, $path, $prefix)</code><p>&nbsp;</p>

+<h1>日期辅助函数</h1>
 
+
 
+<p>日期辅助函数的文件涵盖了一些用于辅助日期数组操作的函数。</p>
 
+
 
+
 
+<h2>装载本辅助函数</h2>
 
+
 
+<p>本辅助函数的装载通过如下代码完成:</p>
 
+
 
+<code>$this-&gt;load-&gt;helper('date');</code>
 
+
 
+
 
+<p>可用的函数如下:</p>
 
+
 
+<h2>now()</h2>
 
+
 
+<p>返回当前的 Unix 时间戳，根据你的config文件中"time reference"设定返回服务器当前时间或者GMT时间。如果你没有计划使用GMT时间(通常是你准备在站点中允许用户选择时区设置)，则此函数跟PHP中time()函数等同。</p>
 
+
 
+
 
+
 
+
 
+<h2>mdate()</h2>
 
+
 
+<p>这个函数跟PHP的内部函数<a href="#">date()</a>几乎是一样的，区别在于，这个函数允许你使用在每个代码字母前带有百分号“%”的MySQL时间表达形式:  %Y %m %d 等。</p>
 
+
 
+<p>采用这种方式处理时间数据的优点在于，避免了你在使用date()函数时经常担心漏掉那些非时间的字符的问题。例如:</p>
 
+
 
+<code>$datestring = "Year: %Y Month: %m Day: %d - %h:%i %a";<br />
 
+$time = time();<br />
 
+<br />
 
+echo mdate($datestring, $time);</code>
 
+
 
+<p>如果第二参数中不包含时间戳则使用当前时间。</p>
 
+
 
+
 
+<h2>standard_date()</h2>
 
+
 
+<p>允许你从一些标准格式生成日期字符串。例子：</p>
 
+
 
+<code>
 
+$format = 'DATE_RFC822';<br />
 
+$time = time();<br />
 
+<br />
 
+
 
+echo standard_date($format, $time);
 
+</code>
 
+
 
+<p>第一个参数必须包含格式，第二个参数必须使用unix时间戳。</p>
 
+
 
+<p>支持格式:</p>
 
+
 
+<table cellpadding="0" cellspacing="1" border="0" style="width:100%" class="tableborder">

+
 
+
 
+<h2>local_to_gmt()</h2>
 
+
 
+<p>将unix时间戳转换为GMT。例子:</p>
 
+
 
+<code>$now = time();<br />
 
+<br />
 
+$gmt = local_to_gmt($now);</code>
 
+
 
+
 
+<h2>gmt_to_local()</h2>
 
+
 
+<p>输入一个GMT的unix时间戳，根据时区、夏时制转换为本地时间戳。例子：</p>
 
+
 
+<code>
 
+$timestamp = '1140153693';<br />
 
+$timezone  = 'UM8';<br />
 
+$daylight_saving = TRUE;<br />
 
+<br />
 
+echo gmt_to_local($timestamp, $timezone, $daylight_saving);</code>
 
+
 
+<p><strong>注意：</strong>时区列表请参考本页末。</p>
 
+
 
+<h2>mysql_to_unix()</h2>
 
+
 
+<p>将MySQL时间戳转换为unix时间戳。例子：</p>
 
+
 
+<code>$mysql = '20061124092345';<br />
 
+<br />
 
+$unix = mysql_to_unix($mysql);</code>
 
+
 
+
 
+<h2>unix_to_human()</h2>
 
+
 
+<p>将unix时间戳转为如下人类可阅读格式：</p>
 
+
 
+<code>YYYY-MM-DD HH:MM:SS AM/PM</code>
 
+
 
+<p>本函数可用于需要作为表单提交的地方。</p>
 
+
 
+<p>时间可以设置为含或者不含秒数，而且可以设为欧洲或美国格式。如果只有时间戳，则格式化为不含秒数的美国格式。例子：</p>
 
+
 
+<code>$now = time();<br />
 
+<br />
 
+echo unix_to_human($now); // U.S. time, no seconds<br />
 
+<br />
 
+echo unix_to_human($now, TRUE, 'us'); // U.S. time with seconds<br />
 
+
 
+<br />
 
+echo unix_to_human($now, TRUE, 'eu'); // Euro time with seconds</code>
 
+
 
+
 
+<h2>human_to_unix()</h2>
 
+
 
+<p>跟上面函数相反，这个函数将“人类”的时间表示方式（如，2008-12-31 04:38 PM）转换成unix的时间表示方式（如：1230713116）。这个函数在你接收一个从表单提交而来的“人类”的时间格式时会很有用。如果传递给这个函数的参数不是如上所说的“人类”时间格式的字符串，哪么它将返回FALSE (boolean)。例如:</p>
 
+
 
+<code>$now = time();<br />
 
+<br />
 
+$human = unix_to_human($now);<br />
 
+<br />
 
+
 
+$unix = human_to_unix($human);</code>
 
+
 
+<h2>timespan()</h2>
 
+
 
+<p>格式化unix时间戳使其看起来像这样：</p>
 
+
 
+<code>1 Year, 10 Months, 2 Weeks, 5 Days, 10 Hours, 16 Minutes</code>
 
+
 
+<p>第一参数必须是unix时间戳，第二个参数是一个大于第一参数的时间戳。如果第二参数空缺，则使用当前时间。这个函数的用途通常是计算过去某一个时间点到现在的时间之间的时间差。例如:</p>
 
+
 
+<code>$post_date = '1079621429';<br />
 
+$now = time();<br />
 
+<br />
 
+echo timespan($post_date, $now);</code>
 
+
 
+<p class="important"><strong>Note:</strong>由本函数生成的文字可以在以下语言文件中找到： language/&lt;your_lang&gt;/date_lang.php</p>
 
+
 
+
 
+<h2>days_in_month()</h2>
 
+
 
+<p>对给出的年月值返回天数。这个函数的实现已经考虑了存在闰年和平年的情况。例如:</p>
 
+<code>echo days_in_month(06, 2005);</code>
 
+
 
+<p>如果省略第二参数则使用当前年。</p>
 
+
 
+<h2>timezones()</h2>
 
+<p>根据给定的时区参考(有效时区列表请参见下面的“时区参考”)返回跟UTC的相差值。</p>
 
+
 
+<p><code>echo timezones('UM5');</code></p>
 
+<p>本函数最有用是在使用timezone_menu()函数时. </p>
 
+
 
+<h2>timezone_menu()</h2>
 
+<p>生成一个时区下拉选单，像这样：</p>
 
+
 
+<img src="../images/timezone_menu.gif" alt="">
 
+
 
+<p>在你需要向你的网站会员提供他们所在时区的设置选项时这个选单会很有用的。</p>
 
+
 
+<p>第一个参数让你设置选单的“已选”状态。例如，你想将美国西部标准时间设为默认时间，你可以这样做：</p>
 
+
 
+<code>echo timezone_menu('UM8');</code>
 
+
 
+<p>要得到这个选单的各个具体值，请看下面的时区参考表。</p>
 
+
 
+<p>第二个参数让你为选单设置CSS的类名。</p>
 
+
 
+<p class="important"><strong>注意:</strong>上面选单里的每个条目可以在这个文件语言文件里找到： language/&lt;your_lang&gt;/date_lang.php</p>
 
+

+<h1>目录辅助函数</h1>
 
+<p>目录辅助函数文件包含处理目录的函数。</p>
 
+
 
+
 
+<h2>载入这个辅助函数</h2>
 
+
 
+<p>请使用如下代码载入这个辅助函数：</p>
 
+<code>$this-&gt;load-&gt;helper('directory');</code>
 
+<p>以下函数可以使用：</p>
 
+
 
+
 
+<h2>directory_map('<var>source directory</var>')</h2>
 
+
 
+<p>这个函数将读取第一个参数所给出的路径的目录，并且返回该目录所包含文件的数据。示例如下：</p>
 
+<code>$map = directory_map('./mydirectory/');</code>
 
+<p class="important"><strong>注意:</strong> 路径总是相对于你的index.php文件。</p>
 
+<p>如果目录含有子文件夹，也将被列出。你可以使用第二个参数（整数）来控制递归的深度。如果深度为 1，则只列出根目录：</p>
 
+<code>$map = directory_map('./mydirectory/', 1);</code>
 
+
 
+<p>默认情况下，返回的数组中不会包括那些隐藏文件。为了覆盖此行为(即显示隐藏的文件--译者加)，你可以设置第三个参数为 <var>true</var> (boolean):</p>
 
+
 
+<code>$map = directory_map('./mydirectory/', FALSE, TRUE);</code>
 
+
 
+<p>每一个文件夹的名字都将作为数组的索引，文件夹所包含的文件将以数字作为索引。下面有个典型的数组示例:</p>
 
+<code>Array<br />
 
+(<br />
 
+&nbsp;&nbsp;&nbsp;[libraries] =&gt; Array<br />
 
+&nbsp;&nbsp;&nbsp;(<br />

+
 
+<p>Email 辅助函数提供了一些辅助功能，用于电子邮件的相关操作。若要了解更多的电子邮件解决方案，请参阅 CodeIgniter 的 <a href="../libraries/email.html">Email 类</a>。</p>
 
+
 
+<h2>装载这个辅助函数</h2>
 
+
 
+<p>本辅助函数的装载通过如下代码完成:</p>
 
+<p><code>$this-&gt;load-&gt;helper('email');</code></p>
 
+
 
+<p>可用的函数如下:</p>
 
+
 
+<h2>valid_email('<var>email</var>')</h2>
 
+
 
+<p>检查 email 是否是一个正确的 email 地址格式。请注意，这实际上并不表示这个地址能接收邮件，只是简单地说明这是一个有效的地址格式。</p>
 
+<p>这个函数返回 TRUE/FALSE</p>
 
+<code> $this-&gt;load-&gt;helper('email');<br />
 
+<br />
 
+if (valid_email('email@somesite.com'))<br />
 
+&#123;<br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;echo 'email is valid';<br />
 
+&#125;<br />
 
+else<br />
 
+&#123;<br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;echo 'email is not valid';<br />
 
+&#125;</code>
 
+<h2>send_email('<var>recipient</var>', '<var>subject</var>', '<var>message</var>')</h2>

+<h1>文件辅助函数</h1>
 
+
 
+<p>文件辅助函数文件包含若干对文件进行操作的函数。</p>
 
+
 
+
 
+<h2>加载</h2>
 
+
 
+<p>使用以下代码：</p>
 
+
 
+<code>$this-&gt;load-&gt;helper('file');</code>
 
+
 
+<p>加载后可用以下函数：</p>
 
+
 
+<h2>read_file&#40;'<var>path</var>'&#41;</h2>
 
+
 
+<p>返回路径为path的文件内容。例：</p>
 
+
 
+<code>$string = read_file&#40;'./path/to/file.php'&#41;;</code>
 
+
 
+<p>可以是相对或者绝对的服务器的路径。如果函数执行失败则返回 FALSE(boolean类型)。</p>
 
+
 
+<p class="important"><strong>提示：</strong> 这里的路径是相对于该站点的index.php所在的路径，而不是当前所在的控制器或视图文件的路径。这是因为CodeIgniter使用的前端控制器(front controller)所以，所有的路径永远都是相对于index.php所在路径。</p>
 
+
 
+<p>如果你的服务器打开了 open_basedir 限制，你可能无法通过上面的方法访问一个文件。</p>
 
+
 
+<h2>write_file&#40;'<var>path</var>', <kbd>$data</kbd>&#41;</h2>
 
+
 
+<p>写进数据到path所指向文件。如果文件不存在则创建之。例：</p>
 
+
 
+<code>
 
+$data = 'Some file data';<br />
 
+<br />
 
+if ( ! write_file&#40;'./path/to/file.php', $data&#41;)<br />
 
+&#123;<br />
 
+&nbsp;&nbsp;&nbsp;&nbsp; echo 'Unable to write the file';<br />
 
+&#125;<br />
 
+
 
+else<br />
 
+&#123;<br />
 
+&nbsp;&nbsp;&nbsp;&nbsp; echo 'File written!';<br />
 
+&#125;</code>
 
+
 
+<p>你可以通过可选的第三个参数来设置文件的读写属性：</p>
 
+
 
+<code>write_file&#40;'./path/to/file.php', $data, <var>'r+'</var>&#41;;</code>
 
+
 
+<p>默认读写属性是 <kbd>wb</kbd>。更多关于文件读写属性参数的内容请参考：<a href="#">PHP user guide</a>。</p>
 
+
 
+<p>注意：要使用此函数写进数据，当前用户对此文件应该是“可写”的，如果该文件不存在则该用户应该对包含该文件的目录有写权限。(即*nux系统下的666,777等)。</p>
 
+
 
+<p class="important"><strong>提示：</strong> 这里的路径是相对于该站点的index.php所在的路径，而不是当前所在的控制器或视图文件的路径。这是因为CodeIgniter使用的前端控制器(front controller)所以，所有的路径永远都是相对于index.php所在路径。</p>
 
+
 
+
 
+<h2>delete_files('<var>path</var>')</h2>
 
+
 
+<p>删除所有包含于path下的文件。例：</p>
 
+<code>delete_files('./path/to/directory/');</code>
 
+
 
+<p>如果第二个参数设为 <kbd>true</kbd>, 则所有在path下的文件夹也会被删除掉。例：</p>
 
+
 
+<code>delete_files('./path/to/directory/', TRUE);</code>
 
+
 
+<p class="important"><strong>提示：</strong> 要被删除的文件必须是当前系统用户所有或者是当前用户对之具有写权限。</p>
 
+
 
+
 
+<h2>get_filenames('<var>path/to/directory/</var>')</h2>
 
+
 
+<p>获取path/to/directory目录下所有文件名组成的数组。如果需要文件名中有其完整路径则可以设置可选的第二个参数为TRUE。</p>
 
+
 
+<h2>get_dir_file_info('<var>path/to/directory/</var>', <kbd>$top_level_only</kbd> = TRUE)</h2>
 
+
 
+<p>获取path/to/directory/目录下的所有文件的文件名，文件大小，日期，文件权限等，并将这些内容保存到返回的数组当中。Sub-folders contained within the specified path are only read if forced
 
+  by sending the second parameter, <kbd>$top_level_only</kbd> to <samp>FALSE</samp>, as this can be an intensive operation.</p>
 
+
 
+<h2>get_file_info('<var>path/to/file</var>', <kbd>$file_information</kbd>)</h2>
 
+
 
+<p>通过给定的路径和文件名，获取到文件path/to/file的文件名，文件大小，文件更改日期等。第二个参数允许你说明需要返回的信息，这个参数的选项包括'name', 'server_path', 'size', 'date', 'readable', 'writable', 'executable', 'fileperms'。如果文件不存在则返回FALSE。</p>
 
+
 
+<p class="important"><strong>注意:</strong> 参数 &quot;writable&quot; 是使用PHP内部的 is_writable() 函数来得到文件读写权限信息的，而这个函数在IIS服务器上存在众所周知的问题。为此，可以考虑使用PHP内部的另一个函数来替换,这个函数就是fileperms()。</p>
 
+<h2>get_mime_by_extension('<var>file</var>')</h2>
 
+
 
+<p>将文件后缀所代表的文件类型按照config/mimes.php里所指明的对应类型进行解释。如果不能决定文件类型，或者不能打开mime配置文件则返回 FALSE。</p>
 
+<p>
 
+<code>$file = &quot;somefile.png&quot;;<br />
 
+echo $file . ' is has a mime type of ' . get_mime_by_extension($file);</code>
 
+</p>
 
+<p class="critical"><strong>注意:</strong> 这并不是一个准确判断文件类型的方式，而仅仅是一种方便的判别方式。不应当在涉及安全问题时使用这种方式。</p>
 
+
 
+<h2>symbolic_permissions(<kbd>$perms</kbd>)</h2>
 
+
 
+<p>将数字式的权限表示方式（如<kbd>fileperms()</kbd>函数所返回值）转换成采用标准符号的标示方式，例如："33279"转换成"-rwxrwxrwx"）。</p>
 
+
 
+<code>echo symbolic_permissions(fileperms('./index.php'));<br />
 
+<br />
 
+// -rw-r--r--</code>
 
+
 
+<h2>octal_permissions(<kbd>$perms</kbd>)</h2>
 
+
 
+<p>将数字式的权限表示方式（如<kbd>fileperms()</kbd>函数所返回值）转换成采用三字符的八进制的标示方式，例如："33279"转换成"777"）。</p>
 
+
 
+<code>echo octal_permissions(fileperms('./index.php'));<br />
 
+<br />
 
+// 644</code><p>&nbsp;</p>

+<h1>表单辅助函数</h1>
 
+
 
+<p>表单辅助函数文件包含那些帮助你使用表单的函数。</p>
 
+
 
+
 
+<h2>载入辅助函数</h2>
 
+
 
+<p>用下面的代码载入该辅助函数：</p>
 
+<code>$this-&gt;load-&gt;helper('form');</code>
 
+
 
+<p>下列函数才可用：</p>
 
+
 
+
 
+
 
+<h2>form_open()</h2>
 
+<p>创建一个开始form标签，相对于你的<strong>配置文档</strong>中的基础URL。允许你添加一些form属性和一些隐藏表单，并且他会基于你的 config.php 文件里设置的编码，自动生成 <kbd>accept-charset</kbd> 这个属性。</p>
 
+<p>使用这个函数而不是直接硬编码HTML的主要的优势是使你的程序可以方便的转换，如果你的URL变化的话。</p>
 
+
 
+<p>下面是一个例子：</p>
 
+
 
+<code>echo form_open('email/send');</code>
 
+
 
+<p>上面的例子会创建一个form提交至你的基础URL加上"email/send" URI片段，像这样：</p>
 
+
 
+<code>&lt;form method="post" accept-charset="utf-8" action="http://example.com/index.php/email/send" /></code>
 
+
 
+<h4>添加一些属性</h4>
 
+
 
+<p>可以在第二个参数里传递一个关联数组来达到这一目的, 像这样：</p>
 
+
 
+<code>
 
+$attributes = array('class' => 'email', 'id' => 'myform');<br />
 
+<br />
 
+echo form_open('email/send', $attributes);</code>
 
+
 
+<p>上面的例子会创建一个这样的form标签：</p>
 
+
 
+<code>&lt;form method="post" accept-charset="utf-8" action="http://example.com/index.php/email/send" &nbsp;class="email" &nbsp;id="myform" /></code>
 
+
 
+<h4>增加隐藏域</h4>
 
+
 
+<p>隐藏域可以使用数组加在第三个参数上，就像这样:</p>
 
+
 
+<code>
 
+$hidden = array('username' => 'Joe', 'member_id' => '234');<br />
 
+<br />
 
+echo form_open('email/send', '', $hidden);</code>
 
+
 
+<p>上面的例子会创建一个这样的form标签和这些隐藏域:</p>
 
+
 
+<code>&lt;form method="post" accept-charset="utf-8" action="http://example.com/index.php/email/send"><br />
 
+&lt;input type="hidden" name="username" value="Joe" /><br />
 
+&lt;input type="hidden" name="member_id" value="234" /></code>
 
+
 
+
 
+<h2>form_open_multipart()</h2>
 
+
 
+<p>这个函数和上面的<dfn>form_open()</dfn>函数完全一样，不同之处在于它多了一个multipart属性。如果你要制作一个上传文件的表单，这个属性是必须的。</p>
 
+
 
+<h2>form_hidden()</h2>
 
+
 
+<p>可以使你创建一个隐藏输入栏。你可以输入name和value来创建一个：</p>
 
+
 
+<code>echo form_hidden('username', 'johndoe');<br />
 
+
 
+<br />
 
+// 将产生:<br /><br />
 
+&lt;input type="hidden" name="username" value="johndoe" /></code>
 
+
 
+<p>或者你也可以使用数组来联合创建它们:</p>
 
+
 
+<code>$data = array(<br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'name'&nbsp;&nbsp;=> 'John Doe',<br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'email' => 'john@example.com',<br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'url'&nbsp;&nbsp;&nbsp;=> 'http://example.com'<br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;);<br />
 
+<br />
 
+echo form_hidden($data);<br />
 
+<br />
 
+// 将产生:<br /><br />
 
+&lt;input type="hidden" name="name" value="John Doe" /><br />
 
+&lt;input type="hidden" name="email" value="john@example.com" /><br />
 
+&lt;input type="hidden" name="url" value="http://example.com" /></code>
 
+
 
+
 
+
 
+
 
+<h2>form_input()</h2>
 
+
 
+<p>可以使你创建一个标准输入栏。你可以在第一和第二个参数里输入name和value来创建一个：</p>
 
+
 
+<code>echo form_input('username', 'johndoe');</code>
 
+
 
+<p>或者你也可以用关联数组来添加你想加入的内容：</p>
 
+
 
+<code>$data = array(<br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'name'&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;=> 'username',<br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'id'&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;=> 'username',<br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'value'&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;=> 'johndoe',<br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'maxlength'&nbsp;&nbsp;&nbsp;=> '100',<br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'size'&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;=> '50',<br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'style'&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; => 'width:50%',<br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;);<br />
 
+<br />
 
+echo form_input($data);<br />
 
+<br />
 
+// 将产生:<br /><br />
 
+&lt;input type="text" name="username" id="username" value="johndoe" maxlength="100" size="50" style="width:50%" /></code>
 
+
 
+<p>如果你想加入一些额外的内容，例如Javascript，你可以在第三个参数里输入字符串来创建它：</p>
 
+
 
+<code>$js = 'onClick="some_function()"';<br />
 
+<br />
 
+echo form_input('username', 'johndoe', $js);</code>
 
+
 
+<h2>form_password()</h2>
 
+
 
+<p>此函数除了是设置type为“password”外和上面的 <dfn>form_input()</dfn> 函数完全一样。</p>
 
+
 
+<h2>form_upload()</h2>
 
+
 
+<p>此函数与上面的 <dfn>form_input()</dfn> 函数几乎完全相同，唯一的区别是此函数所设置的 type 为 "file"，用来上传文件。</p>
 
+
 
+<h2>form_textarea()</h2>
 
+
 
+<p>此函数与上面的 <dfn>form_input()</dfn> 函数几乎完全相同，唯一的区别是此函数所生成的是一个"textarea"。说明：上面的范例中所指定的 "maxlength" 和 "size" 属性在这里变成了 "rows" 和 "cols"。</p>
 
+
 
+
 
+<h2>form_dropdown()</h2>
 
+
 
+<p>创建一个标准的下拉列表字段。第一个参数是字段名，第二个参数是一个包含各个选项的关联数组，第三个参数是你想要设置为默认被选中的值。第三个参数也可以是一个包含多个项目的数组，CI 将为你创建多选下拉列表。例如：</p>
 
+
 
+<code>$options = array(<br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'small'&nbsp;&nbsp;=> 'Small Shirt',<br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'med'&nbsp;&nbsp;&nbsp;&nbsp;=> 'Medium Shirt',<br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'large'&nbsp;&nbsp; => 'Large Shirt',<br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'xlarge' => 'Extra Large Shirt',<br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;);<br />
 
+<br />
 
+$shirts_on_sale = array('small', 'large');<br />
 
+<br />
 
+echo form_dropdown('shirts', $options, 'large');<br />
 
+<br />
 
+// 将会生成:<br />
 
+<br />
 
+&lt;select name=&quot;shirts&quot;&gt;<br />
 
+&lt;option value=&quot;small&quot;&gt;Small Shirt&lt;/option&gt;<br />
 
+&lt;option value=&quot;med&quot;&gt;Medium  Shirt&lt;/option&gt;<br />
 
+&lt;option value=&quot;large&quot; selected=&quot;selected&quot;&gt;Large Shirt&lt;/option&gt;<br />
 
+&lt;option value=&quot;xlarge&quot;&gt;Extra Large Shirt&lt;/option&gt;<br />
 
+&lt;/select&gt;<br />
 
+<br />
 
+echo form_dropdown('shirts', $options, $shirts_on_sale);<br />
 
+<br />
 
+// 将会生成:<br />
 
+<br />
 
+&lt;select name=&quot;shirts&quot; multiple=&quot;multiple&quot;&gt;<br />
 
+&lt;option value=&quot;small&quot; selected=&quot;selected&quot;&gt;Small Shirt&lt;/option&gt;<br />
 
+&lt;option value=&quot;med&quot;&gt;Medium  Shirt&lt;/option&gt;<br />
 
+&lt;option value=&quot;large&quot; selected=&quot;selected&quot;&gt;Large Shirt&lt;/option&gt;<br />
 
+&lt;option value=&quot;xlarge&quot;&gt;Extra Large Shirt&lt;/option&gt;<br />
 
+&lt;/select&gt;</code>
 
+
 
+
 
+<p>如果你希望 &lt;select&gt; 开始标签包含一些额外的属性，例如 <kbd>id</kbd> 属性以及JavaScript，你可以将一个字符串作为第四个参数传递过去:</p>
 
+
 
+<code>$js = 'id="shirts" onChange="some_function();"';<br />
 
+<br />
 
+echo form_dropdown('shirts', $options, 'large', $js);</code>
 
+
 
+<p>如果$options参数是一个多维数组，form_dropdown() 函数将使用数组的键作为 label值生成一个 &lt;optgroup&gt; 标签。</p>
 
+
 
+
 
+<h2>form_multiselect()</h2>
 
+
 
+<p>该函数可以生成标准的复选列表。第一个参数给出表单项的名称；第二个参数用一个关联数组给出该表单项的全部可选项列表；第三个参数规定哪几项是默认已选取的。这些参数的用法跟上面的<kbd>form_dropdown()</kbd>完全一样。当然，由于是复选的，在处理传值的时候，我们要使用数组的语法。数组语法的例子：<samp>foo[]</samp>。</p>
 
+
 
+<h2>form_fieldset()</h2>
 
+
 
+<p>帮助你生成fieldset/legend标签。</p>
 
+<code>echo form_fieldset('Address Information');<br />
 
+echo &quot;&lt;p&gt;fieldset content here&lt;/p&gt;\n&quot;;<br />
 
+echo form_fieldset_close();
 
+<br />
 
+<br />
 
+// 生成<br />
 
+&lt;fieldset&gt; 
+<br />
 
+&lt;legend&gt;Address Information&lt;/legend&gt;  
+<br />
 
+&lt;p&gt;form content here&lt;/p&gt;  
+<br />
 
+&lt;/fieldset&gt;</code>
 
+<p>与其它函数类似，在第二个参数你可以传递一个关联数组来添加你自己想要的自定义的属性。</p>
 
+<p><code>$attributes = array('id' =&gt; 'address_info', 'class' =&gt; 'address_info');<br />
 
+    echo form_fieldset('Address Information', $attributes);<br />
 
+echo &quot;&lt;p&gt;fieldset content here&lt;/p&gt;\n&quot;;<br />
 
+echo form_fieldset_close(); <br />
 
+<br />
 
+// 生成<br />
 
+&lt;fieldset id=&quot;address_info&quot; class=&quot;address_info&quot;&gt; <br />
 
+&lt;legend&gt;Address Information&lt;/legend&gt; <br />
 
+&lt;p&gt;form content here&lt;/p&gt; <br />
 
+&lt;/fieldset&gt;</code></p>
 
+<h2>form_fieldset_close()</h2>
 
+<p>生成一个结束的fieldset标签。唯一的优势是，使用该函数，你可以传递数据，这些数据会附加在这个标签的后面。例如：</p>
 
+<code>$string = &quot;&lt;/div&gt;&lt;/div&gt;&quot;;<br />
 
+<br />
 
+echo form_fieldset_close($string);<br />
 
+<br />
 
+// 会生成：<br />
 
+&lt;/fieldset&gt;<br />
 
+&lt;/div&gt;&lt;/div&gt;</code>
 
+
 
+<h2>form_checkbox()</h2>
 
+<p>作用是生成一个复选框。简单范例如下:</p>
 
+<code>echo form_checkbox('newsletter', 'accept', TRUE);<br />
 
+<br />
 
+// 将会生成:<br />
 
+<br />
 
+&lt;input type=&quot;checkbox&quot; name=&quot;newsletter&quot; value=&quot;accept&quot; checked=&quot;checked&quot; /&gt;</code>
 
+<p>第三个参数为 TRUE/FALSE 布尔值，决定复选框是否被默认选中。</p>
 
+<p>与其它表单辅助函数相似的是，你可以把包含了属性值的数组作为参数传递给本函数:</p>
 
+
 
+<code>$data = array(<br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;'name'&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;=> 'newsletter',<br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;'id'&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;=> 'newsletter',<br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;'value'&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;=> 'accept',<br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;'checked'&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;=> TRUE,<br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;'style'&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; => 'margin:10px',<br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;);<br />
 
+<br />
 
+echo form_checkbox($data);<br />
 
+<br />
 
+// 将会生成:<br /><br />
 
+&lt;input type="checkbox" name="newsletter" id="newsletter" value="accept" checked="checked" style="margin:10px" /></code>
 
+
 
+<p>与其它函数相似的，如果你希望此标签包含额外的数据，例如JavaScript，你可以将一个字符串作为第四个参数传递过去:</p>
 
+
 
+<code>$js = 'onClick="some_function()"';<br />
 
+<br />
 
+ echo form_checkbox('newsletter', 'accept', TRUE, $js)</code>
 
+
 
+
 
+<h2>form_radio()</h2>
 
+<p>此函数与上面的 <dfn>form_checkbox()</dfn> 函数几乎完全相同，唯一的区别是此函数生成的是 "radio" 单选框。</p>
 
+
 
+
 
+<h2>form_submit()</h2>
 
+
 
+<p>帮助你生成一个标准的submit按钮。示例如下：</p>
 
+<code>echo form_submit('mysubmit', 'Submit Post!');<br />
 
+<br />
 
+// 会生成：<br />
 
+<br />
 
+&lt;input type=&quot;submit&quot; name=&quot;mysubmit&quot; value=&quot;Submit Post!&quot; /&gt;</code>
 
+<p>与其它函数类似，第一个参数你可以传递一个关联数组来设置你所需要的属性。第三个参数允许你添加一些额外的内容到生成的HTML代码里。</p>
 
+
 
+<h2>form_label()</h2>
 
+<p>帮助你生成一个label.示例如下：</p>
 
+<code>echo form_label('你的名字是？','username');<br />
 
+<br />
 
+// 会生成:
 
+<br />
 
+&lt;label for=&quot;username&quot;&gt;你的名字是？&lt;/label&gt;</code>
 
+<p>与其它函数类似，你可以在第三个参数传入一个关联数组来增加一些额外的属性值。</p>
 
+<p><code>$attributes = array(<br />
 
+      'class' =&gt; 'mycustomclass',<br />
 
+      'style' =&gt; 'color: #000;',<br />
 
+);<br />
 
+    echo form_label('你的名字是？', 'username', $attributes);<br />
 
+        <br />
 
+// 会生成: <br />
 
+&lt;label for=&quot;username&quot; class=&quot;mycustomclass&quot; style=&quot;color: #000;&quot;&gt;你的名字是？&lt;/label&gt;</code></p>
 
+<h2>form_reset()</h2>
 
+
 
+<p>作用是生成一个标准的 reset 按钮。此函数用法与 <dfn>form_submit()</dfn> 完全相同。</p>
 
+
 
+
 
+<h2>form_button()</h2>
 
+
 
+<p>作用是生成一个标准的按钮。你至少要给出两个参数，它们分别是按钮的名称和内容:</p>
 
+<code>
 
+echo form_button('name','content');<br />
 
+<br />
 
+// 将会生成<br />
 
+&lt;button name="name" type="button"&gt;Content&lt;/button&gt;
 
+</code>
 
+
 
+或者你也可以将一个包含有任何你想要的数据的关联数组作为参数传递过去:
 
+<code>
 
+$data = array(<br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;'name' => 'button',<br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;'id' => 'button',<br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;'value' => 'true',<br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;'type' => 'reset',<br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;'content' => 'Reset'<br />
 
+);<br />
 
+<br />
 
+echo form_button($data);<br />
 
+<br />
 
+// 将会生成:<br />
 
+&lt;button name="button" id="button" value="true" type="reset"&gt;Reset&lt;/button&gt;
 
+</code>
 
+
 
+如果你希望表单包含一些额外的数据，例如JavaScript，你可以将一个字符串作为第三个参数传递过去:
 
+<code>
 
+$js = 'onClick="some_function()"';<br /><br />
 
+echo form_button('mybutton', 'Click Me', $js);
 
+</code>
 
+
 
+
 
+<h2>form_close()</h2>
 
+
 
+<p>作用是生成一个关闭 &lt;/form> 标签。使用此函数的唯一好处是，你可以将这个标签之后要添加的数据也传递过去。例如：</p>
 
+
 
+<code>$string = "&lt;/div>&lt;/div>";<br />
 
+<br />
 
+echo form_close($string);<br />
 
+<br />
 
+// 将会生成:<br />
 
+<br />
 
+&lt;/form><br />
 
+&lt;/div>&lt;/div></code>
 
+
 
+
 
+
 
+
 
+
 
+<h2>form_prep()</h2>
 
+
 
+<p>允许你放心地在表单元素中使用HTML字符(例如引号)，不必担心破坏表单。考虑一下下面这个范例:</p>
 
+
 
+<code>$string = 'Here is a string containing <strong>"quoted"</strong> text.';<br />
 
+<br />
 
+&lt;input type="text" name="myform" value="&lt;var&lt;$string&lt;/var&lt;" /></code>
 
+
 
+<p>因为上面的字符串中包含了引号，因而导致表单被破坏。form_prep()函数会转换HTML，因此可以放心使用:</p>
 
+
 
+<code>&lt;input type="text" name="myform" value="&lt;var&lt;&lt;?php echo form_prep($string); ?&gt;&lt;/var&lt;" /></code>
 
+
 
+<p class="important"><strong>说明:</strong> 如果你使用的是表单辅助函数中的任何一个，数据都会自动的进行预处理，所以没有必要调用本函数。只有当你手动创建表单元素时，你才需要本函数。</p>
 
+
 
+
 
+
 
+<h2>set_value()</h2>
 
+
 
+<p>允许你设置 input 或者 textarea 字段的值。你必须在第一个参数中指定字段名称。第二个参数是可选的，允许你给字段设置一个默认值。例如:</p>
 
+
 
+<code>&lt;input type="text" name="quantity" value="&lt;?php echo set_value('quantity', '0'); ?&gt;" size="50" /></code>
 
+
 
+<p>当上面的表单元素第一次加载时将会显示"0"。</p>
 
+
 
+<h2>set_select()</h2>
 
+
 
+<p>如果你使用 <dfn>&lt;select></dfn> 下拉菜单，此函数允许你显示选中的菜单项。第一个参数必须包含下拉菜单的名称，第二个参数必须包含每个菜单项的值。第三个参数是可选的，作用是设置菜单项为默认选中状态(使用TRUE/FALSE布尔值)。</p>
 
+
 
+<p>范例:</p>
 
+
 
+<code>
 
+&lt;select name="myselect"><br />
 
+&lt;option value="one" <dfn>&lt;?php echo  set_select('myselect', 'one', TRUE); ?&gt;</dfn> >One&lt;/option><br />
 
+&lt;option value="two" <dfn>&lt;?php echo  set_select('myselect', 'two'); ?&gt;</dfn> >Two&lt;/option><br />
 
+&lt;option value="three" <dfn>&lt;?php echo  set_select('myselect', 'three'); ?&gt;</dfn> >Three&lt;/option><br />
 
+&lt;/select>
 
+</code>
 
+
 
+
 
+<h2>set_checkbox()</h2>
 
+
 
+<p>允许你显示一个处于提交状态的复选框。第一个参数必须包含此复选框的名称，第二个参数必须包含它的值，第三个参数是可选的，作用是设置复选框为默认选中状态(使用TRUE/FALSE布尔值)。例如:</p>
 
+
 
+<code>&lt;input type="checkbox" name="mycheck" value="1" <dfn>&lt;?php echo set_checkbox('mycheck', '1'); ?&gt;</dfn> /><br />
 
+&lt;input type="checkbox" name="mycheck" value="2" <dfn>&lt;?php echo set_checkbox('mycheck', '2'); ?&gt;</dfn> /></code>
 
+
 
+
 
+<h2>set_radio()</h2>
 
+
 
+<p>允许你显示那些处于提交状态的单选框。这个函数与前面的 <strong>set_checkbox()</strong> 是相同的。</p>
 
+
 
+<code>&lt;input type="radio" name="myradio" value="1" <dfn>&lt;?php echo  set_radio('myradio', '1', TRUE); ?&gt;</dfn> /><br />
 
+&lt;input type="radio" name="myradio" value="2" <dfn>&lt;?php echo  set_radio('myradio', '2'); ?&gt;</dfn> /></code><p>&nbsp;</p>

+</ul>
 
+
 
+<h2>装载辅助函数</h2>
 
+
 
+<p>本辅助函数的装载通过如下代码完成:</p>
 
+
 
+<code>$this-&gt;load-&gt;helper('html');</code>
 
+
 
+<p>可用的函数如下：</p>
 
+
 
+<h2><a name="br"></a>br()</h2>
 
+<p>生成指定个数的换行标签 (&lt;br />) 。例如：</p>
 
+<code>echo br(3);</code>
 
+<p>如上代码将显示： &lt;br />&lt;br />&lt;br /></p>
 
+
 
+<h2><a name="heading"></a>heading()</h2>
 
+<p>帮助你创建 HTML &lt;h1> 标签.  第一个字段用于标记显示内容，第二个字段用于标该标签所用字号。例如：</p>
 
+<code>echo heading('Welcome!', 3);</code>
 
+<p>如上代码将显示：  &lt;h3>Welcome!&lt;/h3></p>
 
+
 
+<p>Additionally, in order to add attributes to the heading tag such as HTML classes, ids or inline styles, a third parameter is available.</p>
 
+<code>echo heading('Welcome!', 3, 'class="pink"')</code>
 
+<p>The above code produces: &lt;h3 class="pink">Welcome!&lt;h3></p>
 
+
 
+
 
+<h2><a name="img"></a>img()</h2>
 
+<p>帮助你创建 HTML &lt;img /&gt; 标签。  第1个参数包含的是图片文件的路径。 例如:</p>
 
+<code>echo img('images/picture.jpg');<br />
 
+// 生成 &lt;img src=&quot;http://site.com/images/picture.jpg&quot; /&gt;</code>
 
+<p>第2个参数是可选的， 其值为TRUE或者FALSE， 作用是决定该函数生成的图片地址中是否包含由$config['index_page']所设置的起始页面。 一般来说， 当你使用媒体控制器时才使用这个。</p>
 
+<p><code>echo img('images/picture.jpg', TRUE);<br />
 
+// 生成 &lt;img src=&quot;http://site.com/index.php/images/picture.jpg&quot; alt=&quot;&quot; /&gt;</code></p>
 
+<p>此外， 关联数组也能够被作为参数传递到 img() 函数中， 用来实现对所有属性和值的完全控制。如果没指定 alt 属性，则 CodeIgniter 将产生一个空字符串。</p>
 
+<p><code> $image_properties = array(<br />
 
+    &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'src' =&gt; 'images/picture.jpg',<br />
 
+    &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'alt' =&gt; 'Me, demonstrating how to eat 4 slices of pizza at one time',<br />
 
+    &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'class' =&gt; 'post_images',<br />
 
+    &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'width' =&gt; '200',<br />
 
+    &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'height' =&gt; '200',<br />
 
+    &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'title' =&gt; 'That was quite a night',<br />
 
+    &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'rel' =&gt; 'lightbox',<br />
 
+    );<br />
 
+    <br />
 
+    echo img($image_properties);<br />
 
+    // &lt;img src=&quot;http://site.com/index.php/images/picture.jpg&quot; alt=&quot;Me, demonstrating how to eat 4 slices of pizza at one time&quot; class=&quot;post_images&quot; width=&quot;200&quot; height=&quot;200&quot; title=&quot;That was quite a night&quot; rel=&quot;lightbox&quot; /&gt;</code></p>
 
+
 
+<h2><a name="link_tag"></a>link_tag()</h2>
 
+<p>帮助你创建 HTML &lt;link /> 标签。在链接样式表以及其他内容时非常有用。参数包括 href 以及可选的 rel, type, title, media 以及 index_page。index_page 是一个TRUE/FALSE 值，作用是决定该函数生成的 href 地址中是否包含由 $config['index_page']所设置的起始页面。<code>
 
+echo link_tag('css/mystyles.css');<br />
 
+// 生成 &lt;link href=&quot;http://site.com/css/mystyles.css&quot; rel=&quot;stylesheet&quot; type=&quot;text/css&quot; /&gt;</code></p>
 
+<p>更多示例:</p>
 
+
 
+<code>
 
+    echo link_tag('favicon.ico', 'shortcut icon', 'image/ico');<br />
 
+    // &lt;link href=&quot;http://site.com/favicon.ico&quot; rel=&quot;shortcut icon&quot; type=&quot;image/ico&quot; /&gt; 
+    <br />
 
+    <br />
 
+    echo link_tag('feed', 'alternate', 'application/rss+xml', 'My RSS Feed');<br />
 
+    // &lt;link href=&quot;http://site.com/feed&quot; rel=&quot;alternate&quot; type=&quot;application/rss+xml&quot; title=&quot;My RSS Feed&quot; /&gt; </code>
 
+<p>此外，关联数组也能够被作为参数传递到 link_tag() 函数中， 用来实现对所有属性和值的完全控制。</p>
 
+<p><code>
 
+    $link = array(<br />
 
+    &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'href' =&gt; 'css/printer.css',<br />
 
+    &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'rel' =&gt; 'stylesheet',<br />
 
+    &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'type' =&gt; 'text/css',<br />
 
+    &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'media' =&gt; 'print'<br />
 
+    );<br />
 
+    <br />
 
+    echo link_tag($link);<br />
 
+    // &lt;link href=&quot;http://site.com/css/printer.css&quot; rel=&quot;stylesheet&quot; type=&quot;text/css&quot; media=&quot;print&quot; /&gt;</code></p>
 
+    
+<h2><a name="nbs"></a>nbs()</h2>
 
+<p>生成不换行的指定个数的空格标签(&amp;nbsp;)。例如：</p>
 
+<code>echo nbs(3);</code>
 
+<p>如上代码将显示： &amp;nbsp;&amp;nbsp;&amp;nbsp;</p>
 
+
 
+<h2><a name="ol_and_ul"></a>ol()&nbsp; 和&nbsp; ul()</h2>
 
+
 
+<p>允许你通过简单或多维的数组生成有序或无序的HTML列表。例如:</p>
 
+
 
+<code>
 
+
 
+$this-&gt;load-&gt;helper('html');<br />
 
+<br />
 
+$list = array(<br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'red', <br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'blue', <br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'green',<br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'yellow'<br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;);<br />
 
+<br />
 
+$attributes = array(<br />
 
+
 
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'class' => 'boldlist',<br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'id'&nbsp;&nbsp;&nbsp;&nbsp;=> 'mylist'<br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;);<br />
 
+<br />
 
+echo ul($list, $attributes);<br />
 
+</code>
 
+
 
+<p>如上代码将显示：</p>
 
+
 
+<code>
 
+&lt;ul&nbsp;class="boldlist"&nbsp;id="mylist"><br />
 
+
 
+&nbsp;&nbsp;&lt;li>red&lt;/li><br />
 
+&nbsp;&nbsp;&lt;li>blue&lt;/li><br />
 
+&nbsp;&nbsp;&lt;li>green&lt;/li><br />
 
+&nbsp;&nbsp;&lt;li>yellow&lt;/li><br />
 
+&lt;/ul>
 
+</code>
 
+
 
+<p>这是一个更复杂的例子，应用了多维数组：</p>
 
+
 
+<code>
 
+$this-&gt;load-&gt;helper('html');<br />
 
+<br />
 
+$attributes = array(<br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'class' => 'boldlist',<br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'id'&nbsp;&nbsp;&nbsp;&nbsp;=> 'mylist'<br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;);<br />
 
+<br />
 
+$list = array(<br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'colors' => array(<br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'red',<br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'blue',<br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'green'<br />

+<h2><a name="meta"></a>meta()</h2>
 
+
 
+<p>帮助你创建meta标签.  你可以将字符串、简单数组或者多维数组传递给函数. 例如:</p>
 
+
 
+<code>
 
+echo meta('description', 'My Great site');<br />
 
+// 生成:  &lt;meta name="description" content="My Great Site" /><br />
 
+<br /><br />
 
+
 
+echo meta('Content-type', 'text/html; charset=utf-8', 'equiv'); // 注意第3个参数.，可以是 "equiv" 或者 "name"<br />
 
+// 生成:  &lt;meta http-equiv="Content-type" content="text/html; charset=utf-8" /><br />
 
+
 
+<br /><br />
 
+
 
+echo meta(array('name' => 'robots', 'content' => 'no-cache'));<br />
 
+// 生成:  &lt;meta name="robots" content="no-cache" /><br />

+<h1>Inflector 辅助函数</h1>
 
+<p>Inflector 辅助函数文件包含允许你把单词更改为复数、单数或骆驼拼写法等形式的函数。</p>
 
+<h2>装载辅助函数</h2>
 
+<p>使用以下代码装载辅助函数：</p>
 
+<p><code>$this-&gt;load-&gt;helper('inflector');</code></p>
 
+<p>以下函数可用：</p>
 
+<h2>singular()</h2>
 
+<p>把一个单词的复数形式更改为单数形式。例如：</p>
 
+<p><code>$word = &quot;dogs&quot;;<br />
 
+echo singular($word); // Returns &quot;dog&quot; </code></p>
 
+<h2>plural()</h2>
 
+<p>把一个单词的单数形式更改为复数形式。例如：</p>
 
+<p><code>$word = &quot;dog&quot;;<br />
 
+echo plural($word); // Returns &quot;dogs&quot; </code></p>
 
+<p>强制单词以&ldquo;es&rdquo;结尾，则把第二个参数置为&ldquo;true&rdquo;。</p>
 
+<p><code>$word = &quot;pass&quot;;<br />
 
+echo plural($word, TRUE); // Returns &quot;passes&quot; </code></p>
 
+<h2>camelize()</h2>
 
+<p>把一个以空格或下划线分隔的单词字符串更改为骆驼拼写法。例如：</p>
 
+<p><code>$word = &quot;my_dog_spot&quot;;<br />
 
+echo camelize($word); // Returns &quot;myDogSpot&quot; </code></p>
 
+<h2>underscore()</h2>
 
+<p>把以空格分隔的多个单词更改为以下划线分隔。例如：</p>
 
+<p><code>$word = &quot;my dog spot&quot;;<br />
 
+echo underscore($word); // Returns &quot;my_dog_spot&quot; </code></p>
 
+<h2>humanize()</h2>
 
+<p>把以下划线分隔的多个单词更改为以空格分隔，并且每个单词以大写开头。例如：</p>
 
+<p><code>$word = &quot;my_dog_spot&quot;;<br />
 
+echo humanize($word); // Returns &quot;My Dog Spot&quot; </code></p><p>&nbsp;</p>

+<h1>安全辅助函数</h1>
 
+
 
+<p>这个安全辅助函数文件包含一系列和安全相关的函数。</p>
 
+
 
+
 
+<h2>加载这个辅助函数</h2>
 
+
 
+<p>辅助函数可以使用如下代码进行加载:</p>
 
+
 
+
 
+<code>$this-&gt;load-&gt;helper('security');</code>
 
+
 
+<p>可以使用下面的函数:</p>
 
+
 
+
 
+<h2>xss_clean()</h2>
 
+
 
+<p>这个函数提供了 XSS 过滤，其实它是<a href="../libraries/input.html">输入类</a>的一个别名，关于更多的信息可以到那里去查看。</p>
 
+
 
+<h2>sanitize_filename()</h2>
 
+
 
+<p>此函数对目录遍历提供保护.  其实它是
 
+<a href="../libraries/security.html">安全类</a>（下$this-&gt;security-&gt;sanitize_filename() 译者注）的一个别名.  更多信息可以到那里去查看.</p>
 
+
 
+<h2>do_hash()</h2>
 
+
 
+<p>允许你创建SHA1或者MD5加密. 可以参考如下例子:</p>
 
+
 
+<code>
 
+$str = do_hash($str); // SHA1<br />
 
+<br />
 
+$str = do_hash($str, 'md5'); // MD5
 
+</code>
 
+
 
+<p class="important"><strong>注：</strong>  该函数原名为<kbd>dohash()</kbd>, 已弃用。现在改为<kbd>do_hash()</kbd>.</p>
 
+
 
+
 
+<h2>strip_image_tags()</h2>
 
+
 
+<p>这个函数可以删除图片的一些不必要字符，目的是让图片的url以文本的形式存在,提高了安全性.</p>
 
+
 
+<code>$string = strip_image_tags($string);</code>
 
+
 
+
 
+<h2>encode_php_tags()</h2>
 
+
 
+<p>这个函数可以把PHP脚本标签强制转成实体对象. <b>Note:</b> 如果你使用了XSS过滤函数的话，会自动转换.</p>
 
+
 
+<code>$string = encode_php_tags($string);</code><p>&nbsp;</p>

+<p>这些笑脸表情是用普通的文本来描述的,像 <dfn>:-)</dfn> 然后再将他们转换成真正的表情<img src="../images/smile.gif" width="19" height="19" border="0" alt="smile!"></p>
 
+
 
+<p>这里显示了许多表情图片，当你点击图片的时候，它们就会被插入到一个表单区域中.比如，你有一个允许用户评论并且可以插入表情的的博客，你的访问用户可以点击满意的表情图片，然后在javascript脚本的帮助下插入到相应的表单区域.</p>
 
+
 
+
 
+<h2>可点击的表情</h2>
 
+
 
+<p>这里有个案例将教给你如何在表单的旁边创建可以点击的各种表情.首先你需要下载并安装表情包,然后再建一个控制器和相应的视图作为描述文件.</p>
 
+
 
+<p class="important"><strong>重点提示：</strong>开始之前,请<a href="#">下载表情图片</a>然后把它们放在可以公开访问的服务器上.这个辅助函数采用数组的形式替换各种表情,在目录
 
+<dfn>application/config/smileys.php</dfn> 中可以查看</p>
 
+
 
+
 
+<h3>控制器</h3>

+<p>在你的<dfn>application/controllers/</dfn>目录中创建一个文件命名为<kbd>smileys.php</kbd> 然后加入下面的代码.</p>
 
+
 
+<p><strong>重点提示:</strong>修改你的表情url在函数<dfn>get_clickable_smileys()</dfn>的参数中，url指向你的<dfn>smiley</dfn>路径.</p>
 
+
 
+<p>可以看到添加表情的时候我们使用的是<a href="../libraries/table.html">Table Class</a>.</p>

+
 
+<p>在你的<dfn>application/views/</dfn>文件夹下,创建一个名字为<kbd>smiley_view.php</kbd>的文件，然后加入下面的代码:</p>
 
+
 
+
 
+<textarea class="textarea" style="width:100%" cols="50" rows="20">
 
+&lt;html>
 
+&lt;head>

+</textarea>
 
+
 
+
 
+<p>当你创建完控制器和视图之后，就可以显示你的表情了 <dfn>http://localhost/index.php/smileys/</dfn></p>
 
+
 
+
 
+<h3>字段别名</h3>
 
+
 
+<p>当修改视图的时候，会牵扯到控制器中的id字段，带来不便。为了解决这一问题，你可以在视图中给表情一个别名，并将其映射到id字段。</p>
 
+<code>$image_array = get_smiley_links("http://localhost/images/smileys/", "comment_textarea_alias");</code>
 
+
 
+<p>将别名映射到id字段, 传递他们两个到smiley_js函数:</p>
 
+<code>$image_array = smiley_js("comment_textarea_alias", "comments");</code>
 
+
 
+
 
+<h1>函数参考</h1>
 
+
 
+
 
+<h2>get_clickable_smileys()</h2>
 
+
 
+<p>返回一个已经绑定了可点击表情的数组。你必须提供表情文件夹的 URL，还有表单域的 ID 或者表单域的别名。</p>
 
+
 
+<code>$image_array = get_smiley_links("http://localhost/images/smileys/", "comment");</code>
 
+<p class="important">Note: Usage of this function without the second parameter, in combination with js_insert_smiley has been deprecated.</p>
 
+
 
+
 
+<h2>smiley_js()</h2>
 
+
 
+<p>生成的 JavaScript 可以让图片点击后插入到表单域中。如果你在生成表情链接的时候提供了一个别名来代替id，你需要在函数中传入别名和相应的form id，
 
+此函数被设计为应放在你web页面的&lt;head&gt;区域</p>
 
+
 
+<code>&lt;?php echo smiley_js(); ?&gt;</code>
 
+<p class="important">Note: This function replaces js_insert_smiley, which has been deprecated.</p>
 
+
 
+
 
+<h2>parse_smileys()</h2>
 
+
 
+<p>输入一个文本字符串，用来替换任何已经被包含的空白文本表情，而两者是等效的.第一个参数必须包含你的字符串,第二个参数是你的表情的存放目录:</p>
 
+
 
+<code>
 
+$str = 'Here are some simileys: :-)  ;-)';<br />
 
+<br />
 
+$str = parse_smileys($str, "http://localhost/images/smileys/");<br />
 
+<br />

+<h1>字符串辅助函数</h1>
 
+
 
+<p>该字符串辅助函数为你提供对字符串类型的各种函数。</p>
 
+
 
+
 
+<h2>装载字符串辅助函数</h2>
 
+
 
+<p>采用如下方式装载该辅助函数：</p>
 
+<code>$this-&gt;load-&gt;helper('string');</code>
 
+
 
+<p>可用函数如下：</p>
 
+
 
+<h2>random_string()</h2>
 
+
 
+<p>根据你所指定的类型和长度产生一个随机字符串。可用于生成密码串或随机字串。</p>
 
+
 
+<p>第一个参数指定字符串类型，第二个参数指定其长度。以下为可选字符串类型：</p>
 
+
 
+ alpha, alunum, numeric, nozero, unique, md5, encrypt 和 sha1
 
+<ul>
 
+<li><strong>alpha</strong>:&nbsp; 含有大小写字母</li>
 
+<li><strong>alnum</strong>:&nbsp; 含有大小写字母以及数字。</li>
 
+<li><strong>numeric</strong>:&nbsp; 数字字符串。</li>
 
+<li><strong>nozero</strong>:&nbsp; 不含零的数字字符串。</li>
 
+<li><strong>unique</strong>:&nbsp; 用 MD5 和 uniqid()加密的字符串。注意：第二个长度参数在这种类型无效。均返回一个32位长度的字符串。</li>
 
+<li><strong>sha1</strong>:&nbsp; 使用<a href="security_helper.html">安全辅助函数</a>中的<kbd>do_hash()</kbd>生成的随机数加密值。</li>
 
+</ul>
 
+
 
+<p>范例：</p>
 
+
 
+<code>echo random_string('alnum', 16);</code>
 
+
 
+
 
+<h2>increment_string()</h2>
 
+
 
+<p>通过附加一个可以增加的数生成一个字符串。Increments a string by appending a number to it or increasing the number. Useful for creating "copies" or a file or duplicating database content which has unique titles or slugs.</p>
 
+
 
+<p>范例:</p>
 
+
 
+<code>echo increment_string('file', '_'); // "file_1"<br/>
 
+echo increment_string('file', '-', 2); // "file-2"<br/>
 
+echo increment_string('file-4'); // "file-5"<br/></code>
 
+
 
+
 
+<h2>alternator()</h2>
 
+
 
+<p>当执行一个循环时，让两个或两个以上的条目轮换使用。范例：</p>
 
+
 
+<code>for ($i = 0; $i < 10; $i++)<br />
 
+&#123;<br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;echo alternator('string one', 'string two');<br />
 
+&#125;<br />
 
+</code>
 
+
 
+<p>你可以任意添加条目的数量，每一次循环后下一个条目将成为返回值。</p>
 
+
 
+<code>for ($i = 0; $i < 10; $i++)<br />
 
+&#123;<br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;echo alternator('one', 'two', 'three', 'four', 'five');<br />
 
+&#125;<br />
 
+</code>
 
+
 
+<p><strong>注意：</strong>为了让多次调用该函数简单方便，调用该函数时请不要带上实参进行重预置。</p>
 
+
 
+
 
+
 
+<h2>repeater()</h2>
 
+<p>重复生成你所提交的数据。范例：</p>
 
+<code>$string = "\n";<br />
 
+echo repeater($string, 30);</code>
 
+
 
+<p>上面的例子将会产生30个空行。</p>
 
+<h2>reduce_double_slashes()</h2>
 
+<p>将字符串中的双斜线(//)转换为单斜线(/)，但不转换形如(http://)的双斜线。范例：</p>
 
+<code>$string = &quot;http://example.com//index.php&quot;;<br />
 
+echo reduce_double_slashes($string); // results in &quot;http://example.com/index.php&quot;</code>
 
+<h2>trim_slashes()</h2>
 
+<p>去掉任何出现在字符串开头或结尾的斜线。范例：<br />
 
+    <br />
 
+    <code>$string = &quot;/this/that/theother/&quot;;<br />
 
+echo trim_slashes($string); // results in this/that/theother</code></p>
 
+
 
+
 
+<h2>reduce_multiples()</h2>
 
+<p>去掉多余的一个紧接着一个重复出现的特殊字符。范例：</p>
 
+<code>
 
+$string="Fred, Bill,, Joe, Jimmy";<br />
 
+$string=reduce_multiples($string,","); //results in "Fred, Bill, Joe, Jimmy"
 
+</code>
 
+<p>该函数可以接受如下的形参:
 
+<code>reduce_multiples(string: text to search in, string: character to reduce, boolean: whether to remove the character from the front and end of the string)</code>
 
+
 
+第一个形参用于传送你所要去掉重复的字符串。第二个形参用于传送你所要去掉的字符。第三个形参默认为 False。如果为True将会去掉出现在字符串开头或结尾的字符(即使字符不重复也去掉)。范例：
 
+
 
+<code>
 
+$string=",Fred, Bill,, Joe, Jimmy,";<br />
 
+$string=reduce_multiples($string, ", ", TRUE); //results in "Fred, Bill, Joe, Jimmy"
 
+</code>
 
+</p> 
+
 
+<h2>quotes_to_entities()</h2>
 
+<p>将字符串中的单引号和双引号转换为相应的 HTML 字符表示。范例：</p>
 
+<code>$string="Joe's \"dinner\"";<br />
 
+$string=quotes_to_entities($string); //results in "Joe&amp;#39;s &amp;quot;dinner&amp;quot;"
 
+</code>
 
+
 
+<h2>strip_quotes()</h2>
 
+<p>去掉字符串中的单引号和双引号。范例：</p>
 
+<code>$string="Joe's \"dinner\"";<br />
 
+$string=strip_quotes($string); //results in "Joes dinner"
 
+</code><p>&nbsp;</p>

+<h1>文本辅助函数</h1>
 
+
 
+<p>文本辅助函数所包含的函数只能对文本进行处理。</p>
 
+
 
+
 
+<h2>装载文本辅助函数</h2>
 
+
 
+<p>采用如下方式装载该辅助函数：</p>
 
+
 
+<code>$this-&gt;load-&gt;helper('text');</code>
 
+
 
+<p>可用函数如下：</p>
 
+
 
+
 
+<h2>word_limiter()</h2>
 
+
 
+<p>根据指定的<strong>词语</strong>(由于是英语，对中文应该是以空格为判断标准，译者注)数目对一段字符串进行截取。范例：</p>
 
+
 
+<code>
 
+
 
+$string = "Here is a nice text string consisting of eleven words.";<br />
 
+<br />
 
+$string = word_limiter($string, 4);<br /><br />
 
+
 
+// Returns:  Here is a nice&#8230;
 
+</code>
 
+
 
+<p>第三个参数是一个可选的符号后缀，默认在截取段后加上省略号(…)。</p>
 
+
 
+
 
+<h2>character_limiter()</h2>
 
+
 
+<p>根据指定的<strong>字符</strong>数目对一段字符串进行截取。它将会保证单词的完整性(对英语单词而言，译者注)，因此可能会造成截取后的字符数目与指定的有一点出入。范例：</p>
 
+
 
+<code>
 
+$string = "Here is a nice text string consisting of eleven words.";<br />
 
+<br />
 
+$string = character_limiter($string, 20);<br /><br />
 
+
 
+// Returns:  Here is a nice text string&#8230;
 
+</code>
 
+
 
+<p>第三个参数是一个可选的符号后缀，默认在截取段后加上省略号(…)。</p>
 
+
 
+
 
+
 
+<h2>ascii_to_entities()</h2>
 
+
 
+<p>将ASCII码转换为字符实体，包括那些在网页中使用时可能导致问题的高位ASCII码和微软Word字符，因此它们能够被正确地显示出来，不受浏览器设置或者数据库可靠存储的影响。本函数部分依赖于你的服务器对字符集的支持，因此并不是在任何情况下都100%的可靠，但在大多数情况下都可以正确地识别正常范围以外的字符(比如重音符号)。例如：</p>
 
+
 
+<code>$string = ascii_to_entities($string);</code>
 
+
 
+
 
+<h2>entities_to_ascii()</h2>
 
+
 
+<p>这个函数与ascii_to_entities()功能相反; 它将字符转变为ASC码.</p>
 
+
 
+<h2>convert_accented_characters()</h2>
 
+
 
+<p>Transliterates high ASCII characters to low ASCII equivalents, useful when non-English characters need to be used where only standard ASCII characters are safely used, for instance, in URLs.</p>
 
+
 
+<code>$string = convert_accented_characters($string);</code>
 
+
 
+<p>This function uses a companion config file <dfn>application/config/foreign_chars.php</dfn> to define the to and from array for transliteration.</p>
 
+
 
+<h2>word_censor()</h2>
 
+
 
+<p>让你可以对文本中的文字进行审核替换。第一个形参用于获取原始字符串。第二个形参用于存放你不允许的文字的数组。第三个形参(可选)用于存放一个替换不允许文字的字段。如果不指定则被替换为“磅”的表示符号：####。范例：</p>
 
+
 
+<code>
 
+$disallowed = array('darn', 'shucks', 'golly', 'phooey');<br />
 
+<br />
 
+$string = word_censor($string, $disallowed, 'Beep!');</code>
 
+
 
+
 
+<h2>highlight_code()</h2>
 
+
 
+<p>对一段代码(PHP,HTML等)进行着色。例如：</p>
 
+
 
+<code>$string = highlight_code($string);</code>
 
+
 
+<p>本函数使用PHP的 highlight_string() 函数，因此所使用的颜色是你在 php.ini 文件中指定的那些。</p>
 
+
 
+
 
+<h2>highlight_phrase()</h2>
 
+
 
+<p>对字符串内的一个短语进行突出显示。第一个参数是原始字符串，第二个参数是你想要突出显示的短语。如果要用HTML标签对短语进行标记，那么第三个和第四个参数分别是你想要对短语使用的HTML打开和关闭标签。例如:</p>
 
+
 
+<code>
 
+$string = "Here is a nice text string about nothing in particular.";<br />
 
+<br />
 
+$string = highlight_phrase($string, "nice text", '&lt;span style="color:#990000">', '&lt;/span>');
 
+</code>
 
+
 
+<p>以上内容将返回:</p>
 
+
 
+<p>Here is a <span style="color:#990000">nice text</span> string about nothing in particular.</p>
 
+
 
+
 
+
 
+<h2>word_wrap()</h2>
 
+
 
+<p>根据指定的<strong>字符</strong>数目对文本进行换行操作，并且保持词语的完整性(对英语单词而言，笔者注)。范例：</p>
 
+
 
+<code>$string = "Here is a simple string of text that will help us demonstrate this function.";<br />
 
+<br />
 
+echo word_wrap($string, 25);<br />
 
+
 
+<br />
 
+// Would produce:<br />
 
+<br />
 
+Here is a simple string<br />
 
+of text that will help<br />
 
+us demonstrate this<br />
 
+function</code>
 
+
 
+<h2>ellipsize()</h2>
 
+
 
+<p>过滤字符串中的标签，在指定的最大长度处切割字符串，并插入一个省略号。</p>
 
+<p>第一个参数是要被省略处理的字符串，第二个参数是目标字符串中字符的数目。第三个参数是省略号在目标字符串的位置，值为0 - 1，从左到右。例如，值为1时，省略号位于目标字符串的右端，值为.5时，位于中间，而值为0时位于左端。</p>
 
+<p>第四个参数是可选的，用于指明使用的省略符号类型，默认使用 <samp>&hellip;</samp> 。</p>
 
+
 
+<code>$str = 'this_string_is_entirely_too_long_and_might_break_my_design.jpg';<br />
 
+<br />
 
+echo ellipsize($str, 32, .5);</code>
 
+
 
+输出:
 
+<code>this_string_is_e&hellip;ak_my_design.jpg</code><p>&nbsp;</p>

+<h1>排版辅助函数</h1>
 
+
 
+<p>这个排版辅助函数文件里的函数能够让你按照相关词性对文本的格局进行排版。</p>
 
+
 
+<h2>载入这个辅助函数</h2>
 
+
 
+<p>请使用如下代码载入这个辅助函数：</p>
 
+
 
+<code>$this-&gt;load-&gt;helper('typography');</code>
 
+
 
+<p>以下函数可以使用：</p>
 
+
 
+
 
+<h2>auto_typography()</h2>
 
+
 
+<p>格式化文本，使其在语义和排版上是正确的HTML。更多信息请参考 <a href="../libraries/typography.html">排版类</a> 。</p>
 
+
 
+<p>例子:</p>
 
+
 
+<code>$string = auto_typography($string);</code>
 
+
 
+<p><strong>注意:</strong> 排版格式可能会增加处理器的负荷，特别是当你有大量的内容需要被处理时。
 
+如果选择使用这个函数的话，你可能需要考虑<a href="../general/caching.html">缓存</a>你的页面。</p>
 
+
 
+
 
+<h2>nl2br_except_pre()</h2>
 
+
 
+<p>如果换行不在标记符 &lt;pre&gt; 里的话，都会被转换成 &lt;br /&gt; 标记符。这个函数除了会忽略标记符&lt;pre&gt; 以外，和PHP自带函数<dfn>nl2br()</dfn>是相等的。</p>
 
+
 
+<p>例子:</p>
 
+
 
+<code>$string = nl2br_except_pre($string);</code><p>&nbsp;</p>

+<h1>URL 辅助函数</h1>
 
+
 
+<p>URL 辅助函数文件包含一些在处理 URL 中很有用的函数</p>
 
+
 
+
 
+<h2>加载辅助函数</h2>
 
+
 
+<p>本辅助函数通过如下代码加载:</p>
 
+
 
+<code>$this-&gt;load-&gt;helper('url');</code>
 
+
 
+<p>可用函数如下:</p>
 
+
 
+<h2>site_url()</h2>
 
+
 
+<p>返回站点的URL, 如果在<dfn>config.php</dfn> 文件中指定了<dfn>base_url</dfn>会返回指定的值，否则自动获取。 当你将URI段作为参数传给这个函数时，index.php 文件名 &#40;或者是你在config中自定义的 <dfn>index_page</dfn> 文件名&#41; 会被加到URL后面, 而且会加上你在config中定义的 <dfn>url_suffix</dfn> 后缀。</p>
 
+
 
+<p>无论什么时候需要生成 URL ，都鼓励您使用该函数, 这样当您的根 URL 改变的时候更具有可移植性。[注：根 URL 指 config.php 中指定的 base_url 和 <dfn>index_page</dfn>--IT不倒翁]</p>
 
+
 
+<p>做为参数传递给该函数的 URI 段可以是一个字符串，也可以是一个数组. 下面是一个字符串的例子:</p>
 
+
 
+<code>echo site_url("news/local/123");</code>
 
+
 
+<p>上面的例子将返回: http://example.com/index.php/news/local/123</p>
 
+
 
+<p><kbd>注意：</kbd>如果config中开启了<kbd>enable_query_strings</kbd>,则连接符由/改为?，上面的url会返回这样：</p>
 
+<p>http://example.com/index.php<kbd>?</kbd>news/local/123</p>
 
+<p>所以这里要注意，如果你开启了get传值的话，请注意这里的变化。</p>
 
+
 
+<p>这是一个以数组形式传递 URI 段的例子:</p>
 
+
 
+<code>
 
+$segments = array('news', 'local', '123');<br />
 
+<br />
 
+
 
+echo site_url($segments);</code>
 
+
 
+
 
+<h2>base_url()</h2>
 
+<p>返回在 config.php 中设定的 base_url. 例:</p>
 
+<code>echo base_url();</code>
 
+
 
+<p>这个函数和site_url返回相同，只是 <dfn>index_page</dfn> 和 <dfn>url_suffix</dfn> 不再被追加。</p>
 
+
 
+<p>和site_url函数一样, 做为参数传递给该函数的 URI 段可以是一个字符串，也可以是一个数组. 下面是一个字符串的例子:</p>
 
+
 
+<code>echo base_url("blog/post/123");</code>
 
+
 
+<p>上面的例子将返回: http://example.com/blog/post/123</p>
 
+
 
+<p>这个函数非常有用,不像site_url()那样，你可以用它指定文件的路径，像是image路径或者css路径，例如： </p>
 
+
 
+<code>echo base_url("images/icons/edit.png");</code>
 
+
 
+<p>上面的例子将输出像这样的结果: http://example.com/images/icons/edit.png</p>
 
+
 
+
 
+<h2>current_url()</h2>
 
+<p>返回当前正在查看的页面的完整URL(包括段)。</p>
 
+
 
+
 
+<h2>uri_string()</h2>
 
+<p>返回任何包含了此函数的页面的URI段。比如说，要是你的URL是这样的:</p>
 
+<code>http://some-site.com/blog/comments/123</code>
 
+
 
+<p>此函数将会返回:</p>
 
+<code>/blog/comments/123</code>
 
+
 
+<p>注：我测试的结果：</p>
 
+<code>blog/comments/123</code>
 
+
 
+<h2>index_page()</h2>
 
+<p>返回在 config.php 中设定的 index_page. 例:</p>
 
+<code>echo index_page();</code>
 
+
 
+
 
+
 
+<h2>anchor()</h2>
 
+
 
+<p>创建基于你的本地站点URL的标准链接地址：【原翻译为锚链接，不妥。该函数实际上是用来快速生成&lt;a>标签链接用的-zehee】</p>
 
+
 
+<code>&lt;a href="http://example.com">Click Here&lt;/a>           //echo anchor('','Click Here','');</code>
 
+
 
+<p>它有三个可选参数:</p>
 
+
 
+<code>anchor(<var>uri segments</var>, <var>text</var>, <var>attributes</var>)</code>
 
+
 
+<p>第一个参数包含你想附加到URL的任何段.像上面的<dfn>site_url()</dfn> 函数一样,段可以是字符串或数组.</p>
 
+
 
+<p><strong>注意:</strong>&nbsp; 如果你创建在应用程序内部的链接没有包含基本URL(http://...),这个参数会从你配置文件信息中自动加载。只需要写上你的 URL 分段即可。</p>
 
+
 
+<p>第二个参数是你想给链接的内容（&lt;a>标签中间的内容）.如果让它为空,将会由URL替代.</p>
 
+
 
+<p>第三个参数包含一组你想附加给链接的属性.这些属性可以是简单的字符串或相关的数组.</p>
 
+
 
+<p>这里有一些例子:</p>
 
+
 
+<code>echo anchor('news/local/123', 'My News', 'title="News title"');</code>
 
+
 
+<p>输出(链接名字'My News'): &lt;a href="http://example.com/index.php/news/local/123" title="News title">My News&lt;/a></p>
 
+
 
+<code>echo anchor('news/local/123', 'My News', array('title' => 'The best news!'));</code>
 
+
 
+<p>输出(鼠标放在上面会有'The best news!'提示): <a href="#" title="The best news!">My News</a></p>
 
+
 
+
 
+<h2>anchor_popup()</h2>
 
+
 
+<p>几乎和<dfn>anchor()</dfn> 函数相同,区别是它会在新窗口打开链接.
 
+
 
+你可以在第三个参数中指定JavaScript窗口属性来控制窗口的打开方式. 如果第三个参数没有设置,它会直接根据你的浏览器设置打开新窗口.这是一个属性设置的例子:</p>
 
+
 
+<code>
 
+
 
+$atts = array(<br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'width'&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;=> '800',<br />
 
+
 
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'height'&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;=> '600',<br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'scrollbars' => 'yes',<br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'status'&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;=> 'yes',<br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'resizable'&nbsp;&nbsp;=> 'yes',<br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'screenx'&nbsp;&nbsp;&nbsp;&nbsp;=> '0',<br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'screeny'&nbsp;&nbsp;&nbsp;&nbsp;=> '0'<br />
 
+
 
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;);<br />
 
+<br />
 
+echo anchor_popup('news/local/123', 'Click Me!', $atts);</code>
 
+
 
+<p>注意: 以上是函数默认设置,你只要根据自己需要设置不同.如果你想函数使用默认设置,直接传一个空数组给第三个参数就行了:</p>
 
+
 
+<code>echo anchor_popup('news/local/123', 'Click Me!', array());</code>
 
+
 
+
 
+<h2>mailto()</h2>
 
+
 
+<p>创建标准HTML电子邮件链接.习惯用例:</p>
 
+
 
+<code>echo mailto('me@my-site.com', 'Click Here to Contact Me');</code>
 
+
 
+<p>像上面的<dfn>anchor()</dfn> 一样, 你可以用第三个参数设置属性.</p>
 
+
 
+
 
+<h2>safe_mailto()</h2>
 
+
 
+<p>用法和上面的函数相同,区别是它用JavaScript写了基于顺序号码的不易识别的mailto版本标签,可以阻止email地址被垃圾邮件截获.</p>
 
+
 
+<h2>auto_link()</h2>
 
+
 
+<p>自动把包含URL和email地址的字串转换成链接. 例如:</p>
 
+
 
+<code>$string = auto_link($string);</code>
 
+
 
+<p>第二个参数决定URL和email是否都转换或其中一个转换.如果参数没有指定默认是两个都转换.Email links are encoded as safe_mailto() as shown above.</p>
 
+
 
+<p>只转换URL:</p>
 
+<code>$string = auto_link($string, 'url');</code>
 
+
 
+<p>只转换Email地址:</p>
 
+<code>$string = auto_link($string, 'email');</code>
 
+
 
+<p>第三个参数决定链接是否都在新窗口打开.参数值可以是TRUE 或 FALSE(boolean):</p>
 
+<code>$string = auto_link($string, 'both', TRUE);</code>
 
+
 
+
 
+<h2>url_title()</h2>
 
+<p>输入一个字符串并且创建用户友好的URL字串.举个例子,你有一个blog,而且你想在URL中使用条目的标题,这个函数就有用了.例如: </p>
 
+
 
+<code>$title = "What's wrong with CSS?";<br />
 
+<br />
 
+$url_title = url_title($title);<br />
 
+<br />
 
+// 输出:  Whats-wrong-with-CSS
 
+</code>
 
+
 
+
 
+<p>第2个参数指定单词之间的分隔符. 默认使用破折号'-'.</p>
 
+
 
+<code>$title = "What's wrong with CSS?";<br />
 
+<br />
 
+$url_title = url_title($title, '_');<br />
 
+<br />
 
+// 输出:  Whats_wrong_with_CSS
 
+</code>
 
+
 
+<p>第3个参数决定了是否强制转换为小写.默认情况下不会.参数类型为布尔值
 
+<dfn>TRUE</dfn>/<dfn>FALSE</dfn>:</p>
 
+
 
+<code>$title = "What's wrong with CSS?";<br />
 
+<br />
 
+$url_title = url_title($title, '_', TRUE);<br />
 
+<br />
 
+// Produces:  whats_wrong_with_css
 
+</code>
 
+
 
+<h2>prep_url()</h2>
 
+<p>在URL中没有<kbd>http://</kbd>的情况下,这个函数可以附加上.像这样把URL字串传递给函数:</p>
 
+<code>
 
+$url = "example.com";<br /><br />
 
+$url = prep_url($url);</code>
 
+
 
+
 
+
 
+
 
+<h2>redirect()</h2>
 
+
 
+<p>通过发送HTTP头，命令客户端转向到您指定的URL。您既可以指定一个完整的URL，也可以对于站内内容，指定基于网站根目录的相对URL。本函数会自动根据您的配置文件，构造出完整的URL。</p>
 
+
 
+<p>你可以设定第二个参数为 location 定位操作(默认)或者 refresh 刷新操作。定位操作比刷新操作执行速度快，但是在Windows服务器上有时会报错。可选的第3个参数允许你发送一个特定的HTTP请求返回码 - 举例来说这可以用来创建303请求重定向来服务于搜索引擎. 默认的请求返回码是302(临时重定向). 第3个参数<em>只</em>使用于'location'重定向, 而不是用于'refresh'. 范例:</p>
 
+
 
+<code>
 
+    //注意！！一定不要忘了加载 $this-&gt;load-&gt;helper('url');<br/>
 
+    <br/>if ($logged_in == FALSE)<br />
 
+&#123;<br />
 
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;redirect('/login/form/', 'refresh');<br />
 
+&#125;<br />
 
+<br />
 
+// with 301 redirect<br />
 
+redirect('/article/13', 'location', 301);</code>
 
+
 
+<p class="important"><strong>注意：</strong>由于此函数需要处理header头文件，因此它必须在向客户端输出任何内容之前调用。<br />
 
+<strong>注意：</strong>如果您想对HTTP头做更细致的设置，您可以使用<a href="../libraries/output.html">输出类</a>的 set_header() 函数。</p><p>&nbsp;</p>

+<h1>安装指导</h1>
 
+
 
+<p>CodeIgniter 安装分为四个步骤：</p>
 
+
 
+<ol>
 
+<li>解压缩安装包。</li>
 
+<li>把 CodeIgniter 文件夹和里面的文件上传到你的服务器。通常 index.php 在根目录。</li>
 
+<li>用任何文本编辑器打开 <dfn>application/config/config.php</dfn> 去设置你的网站根 URL。如果你打算使用加密或 Session，请设置你的加密密钥。</li>
 
+<li>如果你打算使用数据库，用任何文本编辑器打开 <dfn>application/config/database.php</dfn> 去设置你的数据库参数。</li>
 
+</ol>
 
+
 
+<p>如果你希望通过隐藏 CodeIgniter 文件的位置来增加安全性，你可以修改 <dfn>system</dfn> 和 <dfn>application</dfn> 目录的名字，把它改成任何你喜欢的名字。如果已经修改了名字，你必须打开主目录下面的 <kbd>index.php</kbd> 文件设置里面的 <samp>$system_path</samp> 和 <samp>$application_folder</samp> 变量，把它设成刚刚修改的新名字。</p>
 
+
 
+<p>为了安全考虑,<dfn>system</dfn>和<dfn>application</dfn>两个文件夹应放到网站根目录（Web Root）以外的地方，这样浏览器就不能够直接访问它们。在默认设置下, 在每个文件夹中都有一个 .htaccess 配置文件以拒绝直接访问, 但是当把代码部署到生产环境时最好移除他们，因为生产环境的 Web 服务可能会不支持 .htaccess 的配置。</p>
 
+
 
+<p>如果你移动了以上两个文件夹,请打开主目录下的<kdb>index.php</kdb>文件并编辑<samp>$system_path</samp>和<samp>$application_folder</samp>两个变量, 最好使用绝对路径进行替换, 例如：'<dfn>/www/MyUser/system</dfn>'.</p>
 
+
 
+<p>另外有一个附加的考虑就是，如果要在生产环境中使用，最好关闭PHP的错误报告以及其他任何与开发时有关的功能，
 
+在CodeIgniter中，可以设置 <kbd>ENVIRONMENT</kbd> 常量来实现这个功能。详细的文档请参阅 <a href="../general/security.html">安全</a> 章节。</p>
 
+
 
+<p>以上就是全部安装过程！</p>
 
+
 
+<p>如果你刚刚接触 CodeIgniter，请阅读用户指南的<a href="../overview/getting_started.html">开始</a>部分，开始学习如何构造动态的 PHP 应用。让我们享受这个过程吧！</p>
 
+
 
+<p>如果下载CodeIgniter之后，对于其中的英文注释看不明白，推荐您到<a href="#">CodeIgniter中国社区</a>学习一下，很多朋友都从那里学到了许多知识，相信您会得到的更多！</p><p>&nbsp;</p>

+<h1>疑难解答</h1>

+<p>如果你发现不管你在 URL 里面写什么都只是出现缺省页面的话，有可能是你的服务器不支持 PATH_INFO 变量，它被用来提供搜索引擎友好的 URL。解决这个问题的第一步是打开 <dfn>application/config/config.php</dfn> 文件，查找 <kbd>URI Protocol</kbd> 信息。在那里推荐你去尝试一些其他的设置方法。如果这些方法都无效，你就需要让 CodeIgniter 去强行加一个问号去标记你的 URL。为了做到这点，打开你的 <kbd>application/config/config.php</kbd> 文件把里面的:</p>
 
+
 
+<code>$config['index_page'] = "index.php";</code>
 
+
 
+<p>修改成这样:</p>

+<h1>Upgrading from 1.2 to 1.3</h1>
 
+
 
+<p class="important"><strong>Note:</strong> The instructions on this page assume you are running version 1.2.  If you
 
+have not upgraded to that version please do so first.</p>
 
+
 
+
 
+<p>Before performing an update you should take your site offline by replacing the index.php file
 
+with a static one.</p>
 
+
 
+
 
+<h2>Step 1: Update your CodeIgniter files</h2>
 
+
 
+<p>Replace the following directories in your "system" folder with the new versions:</p>
 
+
 
+<p class="important"><strong>Note:</strong> If you have any custom developed files in these folders please make copies of them first.</p>
 
+
 
+<ul>
 
+<li>application/<strong>models</strong>/&nbsp;&nbsp;  (new for 1.3)</li>
 
+
 
+<li>codeigniter&nbsp;&nbsp;   (new for 1.3)</li>
 
+<li>drivers</li>
 
+<li>helpers</li>
 
+<li>init</li>
 
+<li>language</li>
 
+<li>libraries</li>
 
+<li>plugins</li>
 
+<li>scaffolding</li>
 
+
 
+</ul>
 
+
 
+
 
+<h2>Step 2: Update your error files</h2>
 
+
 
+<p>Version 1.3 contains two new error templates located in <dfn>application/errors</dfn>, and for naming consistency the other error templates have
 
+been renamed.</p>
 
+
 
+<p>If you <strong>have not</strong> customized any of the error templates simply
 
+replace this folder:</p>
 
+
 
+<ul>
 
+<li>application/errors/</li>
 
+</ul>
 
+
 
+<p>If you <strong>have</strong> customized your error templates, rename them as follows:</p>
 
+
 
+
 
+<ul>
 
+<li>404.php&nbsp;&nbsp; =&nbsp; error_404.php</li>
 
+
 
+<li>error.php&nbsp;&nbsp; =&nbsp; error_general.php</li>
 
+<li>error_db.php&nbsp;&nbsp; (new)</li>
 
+<li>error_php.php&nbsp;&nbsp; (new)</li>
 
+</ul>
 
+
 
+
 
+<h2>Step 3: Update your index.php file</h2>
 
+
 
+<p>Please open your main <dfn>index.php</dfn> file &#40;located at your root&#41;.  At the very bottom of the file, change this:</p>
 
+
 
+<code>require_once BASEPATH.'libraries/Front_controller'.EXT;</code>
 
+
 
+<p>To this:</p>
 
+
 
+<code>require_once BASEPATH.'codeigniter/CodeIgniter'.EXT;</code>
 
+
 
+
 
+<h2>Step 4: Update your config.php file</h2>
 
+
 
+<p>Open your <dfn>application/config/config.php</dfn> file and add these new items:</p>
 
+
 
+<pre>
 
+/*
 
+|------------------------------------------------
 
+| URL suffix
 
+|------------------------------------------------
 
+|
 
+| This option allows you to add a suffix to all URLs.
 
+| For example, if a URL is this:
 
+|
 
+| example.com/index.php/products/view/shoes
 
+|
 
+| You can optionally add a suffix, like ".html",
 
+| making the page appear to be of a certain type:
 
+|
 
+| example.com/index.php/products/view/shoes.html
 
+|
 
+*/
 
+$config['url_suffix'] = "";
 
+
 
+
 
+/*
 
+|------------------------------------------------
 
+| Enable Query Strings
 
+|------------------------------------------------
 
+|
 
+| By default CodeIgniter uses search-engine and
 
+| human-friendly segment based URLs:
 
+|
 
+| example.com/who/what/where/
 
+|
 
+| You can optionally enable standard query string
 
+| based URLs:
 
+|
 
+| example.com?who=me&what;=something&where;=here
 
+|
 
+| Options are: TRUE or FALSE (boolean)
 
+|
 
+| The two other items let you set the query string "words"
 
+| that will invoke your controllers and functions:
 
+| example.com/index.php?c=controller&m;=function
 
+|
 
+*/
 
+$config['enable_query_strings'] = FALSE;
 
+$config['controller_trigger'] = 'c';
 
+$config['function_trigger'] = 'm';
 
+</pre>
 
+
 
+
 
+<h2>Step 5: Update your database.php file</h2>
 
+
 
+<p>Open your <dfn>application/config/database.php</dfn> file and add these new items:</p>
 
+
 
+<pre>
 
+$db['default']['dbprefix'] = "";
 
+$db['default']['active_r'] = TRUE;
 
+</pre>
 
+
 
+
 
+<h2>Step 6: Update your user guide</h2>
 
+
 
+<p>Please also replace your local copy of the user guide with the new version.</p><p>&nbsp;</p>

+<h1>Upgrading from 1.3.2 to 1.3.3</h1>
 
+
 
+<p class="important"><strong>Note:</strong> The instructions on this page assume you are running version 1.3.2.  If you
 
+have not upgraded to that version please do so first.</p>
 
+
 
+<p>Before performing an update you should take your site offline by replacing the index.php file with a static one.</p>
 
+
 
+
 
+
 
+<h2>Step 1: Update your CodeIgniter files</h2>
 
+
 
+<p>Replace the following directories in your "system" folder with the new versions:</p>
 
+
 
+<p class="important"><strong>Note:</strong> If you have any custom developed files in these folders please make copies of them first.</p>
 
+
 
+<ul>
 
+<li>codeigniter</li>
 
+<li>drivers</li>
 
+<li>helpers</li>
 
+
 
+<li>init</li>
 
+<li>libraries</li>
 
+</ul>
 
+
 
+
 
+<h2>Step 2: Update your Models</h2>
 
+
 
+<p>If you are <strong>NOT</strong> using CodeIgniter's <a href="../general/models.html">Models</a> feature disregard this step.</p>
 
+
 
+<p>As of version 1.3.3, CodeIgniter does <strong>not</strong> connect automatically to your database when a model is loaded.  This
 
+allows you greater flexibility in determining which databases you would like used with your models.  If your application is not connecting
 
+to your database prior to a model being loaded you will have to update your code.  There are several options for connecting,
 
+<a href="../general/models.html">as described here</a>.</p>
 
+
 
+
 
+<h2>Step 3: Update your user guide</h2>
 
+
 
+<p>Please also replace your local copy of the user guide with the new version.</p><p>&nbsp;</p>
