Zend Framework は、Zend Company によって開発された PHP5 に完全に基づいたオープンソースの PHP 開発フレームワークであり、ZF はアプリケーションのさまざまな部分を分離する MVC (Model–View-Controller) アーキテクチャ パターンを採用しています。プログラムの開発とメンテナンスを容易にするため。この記事では、Zend Framework チュートリアルでの Zend_Controller_Plugin プラグインの使用法について説明します。参考のために皆さんと共有してください。詳細は次のとおりです:
Zend_Controller_Plugin を通じてフロントエンド コントローラーに追加機能を追加できます。いくつかの特殊な機能に便利です。以下は Zend_Controller_Plugin の簡単な紹介です。

Zend_Controller_Plugin_Abstract声明定义了Zend_Controller运行过程中的几个关键事件位置。用户可以通过指定的方法，对指定位置的请求和相应对象进行相关操作。
Zend_Controller_Plugin_Abstract中方法的描述如下：
routeStartup() 在 Zend_Controller_Front 向注册的 路由器 发送请求前被调用。routeShutdown()在
路由器 完成请求的路由后被调用。dispatchLoopStartup() 在 Zend_Controller_Front
进入其分发循环（dispatch loop）前被调用。preDispatch() 在动作由 分发器
分发前被调用。该回调方法允许代理或者过滤行为。通过修改请求和重设分发标志位（利用
Zend_Controller_Request_Abstract::setDispatched(false)
）当前动作可以跳过或者被替换。postDispatch() 在动作由 分发器
分发后被调用。该回调方法允许代理或者过滤行为。通过修改请求和重设分发标志位（利用
Zend_Controller_Request_Abstract::setDispatched(false)
）可以指定新动作进行分发。dispatchLoopShutdown() 在 Zend_Controller_Front 推出其分发循环后调用。
Zend_Controller_Plugin提供的默认插件:
Zend_Controller_Plugin_Broker:插件经纪人，用于注册，管理自定义的Zend_Controller插件。具体用法，可以参考类代码。Zend_Controller_Plugin_ActionStack:用于管理动作堆栈。具体用法，可以参考类代码。Zend_Controller_Plugin_ErrorHandler:用来处理抛出的异常。具体用法，可以参考类代码。Zend_Controller_Plugin_PutHandler:用于处理请求操作
PUT 。具体用法，可以参考类代码。Zend_Controller_Plugin_Broker
