一个做页面静态化的php类

来源:互联网 

<?php
namespace Common;
/* *
 * 功效:页面静态化的创立和删除
 *      创立:当且仅当,一个页面须要被静态化并且还未静态化时。
 *      删除:当且仅当,一个页面存在静态化页面并且须要被重新静态化时。
 *
 * 著作:郭军周
 *
 * 注 :本类基于ThinkPHP3.2,或其他具有“单一入口且MVC模式”的其他php框架。
 *
 * 应用方法:在Controller的结构办法中获得其对象;在Controller的烧毁办法里,用其对象的_static办法。
 *      例:XXXController extends BaseController.
 *         BaseController:
 *         function __construct(){
 *             $this->__sh = StaticHtml::getInstance();
 *         }
 *         function __destruct(){
 *             $this->__sh->_static();
 *         }
 *
