"Cannot load C:/php/php5apache2.dll into server: "或者:"The requested operation has failed"

LoadModule php5_module C:/php5/php5apache2.dll         
//注意：其中C:/php5/php5apache2.dll是你安装php的相应路径.不要把php5apache2.dll和 php5apache.dll混淆.
php5apache.dll只适用于apache 版本1的.
PHP5压缩包里的php5apache2.dll只适用于apache2.0.*版本,
如果是2.2.*以上版本,就可能会出现 "Cannot load C:/php/php5apache2.dll into server: The specified module could not be found."或者:"The requested operation has failed",
改成/php5apache2_2.dll即可
