请教一下， apache 服务器通过 mod_php 或 apache2handler.dll 配置 PHP 的运行，两者有什么区别了？

There are (at least) two ways of running PHP, when working with Apache :

Using CGI : a PHP process is launched by Apache, and it is that PHP process that interprets PHP code -- not Apache itself

Using PHP as an Apache module (called mod_php) : the PHP interpreter is then kind of "embedded" inside the Apache process : there is no external PHP process -- which means that Apache and PHP can communicate better.
