这几天好像不少人都关心用模板的问题。在这里我就把自己的模类贴出来。

我这个类是是继承于phplib7.0的template，并修改相关的程序。做了简单的优化，其实phplib7.0的模板处理比fasttemplate的来得快，经多次test.

PHP:







<?php



if(!defined("__TEMPLATE_H_PHP__")){



define("__TEMPLATE_H_PHP__","template.h.php");



/******************** CODE START ********************/







//PHP类库:template.h.php



//运行环境:PHP4.0



//修改时间:2002-08-01



//最后修改:stangly.wrong



//类库简介:模板的提取显示的类
