<h1>从 1.7.1 升级到 1.7.2</h1>

<p>在进行升级之前，你应该先通过替换 index.php 为静态页面的方式来使你的网站变为脱机状态。</p>


<h2>第1步: 升级你的 CodeIgniter 文件</h2>

<p>将 "system" 目录下的这些文件和目录替换为新版本:</p>

<ul>

<li><dfn>system/codeigniter</dfn></li>
<li><dfn>system/database</dfn></li>
<li><dfn>system/helpers</dfn></li>
<li><dfn>system/language</dfn></li>
<li><dfn>system/libraries</dfn></li>
</ul>

<p class="important"><strong>说明:</strong> 如果你在这些目录下有自己编写的文件，你应该先备份它们。</p>

<h2>第2步: 将404错误模板中的 header() 移除</h2>
<p>如果你的404错误模板中使用了 header() ，例如下面显示的默认 <samp>error_404.php</samp> 模板，请移除那一行代码。</p>

<code>&lt;?php header(&quot;HTTP/1.1 404 Not Found&quot;); ?&gt;</code>

<p>现在 show_404() 方法自身已经可以很好地处理404状态头。</p>

<h2>第3步: 升级你的用户手册</h2>

<p>请将你的本地用户手册替换为新版本，包括图片文件。</p><p>&nbsp;</p>
