返回类型	void

页面重定向示例

创建一个名为 Redirect_controller.php 的控制器，并将其保存在 application/controller/Redirect_controller.php 中

<?php 
   class Redirect_controller extends CI_Controller { 
  </span><span class="kwd">public</span><span class="pln"> </span><span class="kwd">function</span><span class="pln"> index</span><span class="pun">()</span><span class="pln"> </span><span class="pun">{</span><span class="pln"> 
     </span><span class="com">/*加载 URL 辅助类*/</span><span class="pln">
     $this</span><span class="pun">-&gt;</span><span class="pln">load</span><span class="pun">-&gt;</span><span class="pln">helper</span><span class="pun">(</span><span class="str">url</span><span class="pun">);</span><span class="pln"> 

     </span><span class="com">/*将用户重定向到某个站点*/</span><span class="pln">
     redirect</span><span class="pun">(</span><span class="str">http://www.learnfk.com</span><span class="pun">);</span><span class="pln"> 
  </span><span class="pun">}</span><span class="pln">
	
  </span><span class="kwd">public</span><span class="pln"> </span><span class="kwd">function</span><span class="pln"> computer_graphics</span><span class="pun">()</span><span class="pln"> </span><span class="pun">{</span><span class="pln"> 
     </span><span class="com">/* 加载 URL 辅助类*/</span><span class="pln">
     $this</span><span class="pun">-&gt;</span><span class="pln">load</span><span class="pun">-&gt;</span><span class="pln">helper</span><span class="pun">(</span><span class="str">url</span><span class="pun">);</span><span class="pln"> 
     redirect</span><span class="pun">(</span><span class="str">http://www.learnfk.com/computer_graphics/index.htm</span><span class="pun">);</span><span class="pln"> 
  </span><span class="pun">}</span><span class="pln"> 

  </span><span class="kwd">public</span><span class="pln"> </span><span class="kwd">function</span><span class="pln"> version2</span><span class="pun">()</span><span class="pln"> </span><span class="pun">{</span><span class="pln"> 
     </span><span class="com">/*加载 URL 辅助类*/</span><span class="pln">
     $this</span><span class="pun">-&gt;</span><span class="pln">load</span><span class="pun">-&gt;</span><span class="pln">helper</span><span class="pun">(</span><span class="str">url</span><span class="pun">);</span><span class="pln"> 

     </span><span class="com">/*将用户重定向到某个内部控制器的方法* /</span><span class="pln">
     redirect</span><span class="pun">(</span><span class="str">redirect/computer_graphics</span><span class="pun">);</span><span class="pln"> 
  </span><span class="pun">}</span><span class="pln"> 
	

}
?>

更改 application/config/routes.php 中的 routes.php 文件，为上述控制器添加路由，并在文件末尾添加以下行。

$route[redirect]=Redirect_controller; 
$route[redirect/version2]=Redirect_controller/version2; 
$route[redirect/computer_graphics]=Redirect_controller/computer_graphics;

在浏览器中键入以下URL。

http://yoursite.com/index.php/redirect

上面的URL将您重定向到learnfk.com网站，如果您访问以下URL，则它将您重定向到learnfk.com上的计算机图形学教程。

http://yoursite.com/index.php/redirect/computer_graphics
