php5apache2_2.dll加不加进去Apache服务

the requested operation has failed，Apache服务无法重启，在cmd里运行提示是

cannot load E:\phpedu\php5.4\php5apache2_2.dll into server

我是这么写的

#1:加载PHP模块

LoadModule php5_module "E:\phpedu\php5.4\php5apache2_2.dll"

#2:配置php.ini文件的正确路径

PHPIniDir E:\phpedu\php5.4

#3:添加php类型文件到Apache服务器中

AddType application/x-httpd-php .php
