<h1>使用 CodeIgniter 类库</h1>

<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>

<h2>创建类库</h2>
<p>请阅读用户手册中关于 <a href="creating_libraries.html">创建你自己的类库</a> 的部分。</p><p>&nbsp;</p>
