1、服务器会根据文件的后缀名去进行解析,如果是HTML文件则服务器不会进行语法解析,而是直接输出到浏览器。2、如果一个页面中全部都是HTML代码而没有需要解析的PHP语法,则没有必要保存为PHP文件,这样反而会降低运行效率。3、如果是需要PHP控制HTML代码的输出,比如需要PHP判断用户是否登陆,如果登陆则输出A,未登录则输出B。这就需要PHP来进行控制了。HTML不能实现这样的功能

本文下载包包含
了一个可运行的示例网站,它的代码注释要比前面的代码注释更详细一些。FastTemplate类可以在http://www.thewebmasters.net/找到,最新的版本号是1.1.0,那里还有一个用于保证该类在PHP 4中正确运行的小补丁。本文下载代码中的类已经经过该补丁的修正。
