Cannot load php5apache2.dll into server Apache is running a threaded MPM,

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

Apache is running a threaded MPM, but your PHP Module is not compiled to be threadsafe. You need to recompile PHP. Pre-configuration failed!

PHP编译模式错了。如果在windows下，需在php.net上下载 PHP 5.2.13 zip package ，不要下debug pakage 或 Non-thread-safe zip package 。若在linux下编译，需去掉--with-openssl 参数。
