Zend Framework教程之路由功能Zend_Controller_Router详解

本文实例讲述了Zend Framework教程之路由功能Zend_Controller_Router用法。分享给大家供大家参考，具体如下：

Zend Framework的路由提供了两个主要功能路由和创建路由。

Zend_Controller_Router的Route类和相应Route目录下的类定义常见的路由操作。

接口Zend_Controller_Router_Interface，类Zend_Controller_Router_Abstract和Zend_Controller_Router_Rewrite完成了基本的路由，创建路由，删除路由的功能。

Zend_Controller_Router路由功能的实现

Zend_Controller_Router_Interface
