apache2.0升级apache2.2后SQL连接代码发生问题

apache2.0升级apache2.2后SQL连接代码发生问题

本来在apache2.0+PHP5环境下运行正常的代码,在我升级到apache2.2后报错,错误信息:
Fatal error: Call to undefined function mssql_connect() in D:\Program Files\Apache Software Foundation\Apache2.2\htdocs\index.php on line 57

我有按照网上说的,将php.ini中extension=php_mssql.dll前的分号去掉,也把extension_dir = "D:\php\ext"定向好了,windows的环境变量PATH也设置好了
还是连不上,还需要该什么地方吗?
看 APACHE logs 文件夹下的APACHE error log

看看有没有关于 mssql 的错误信息.

只有着2个错好像
通过phpinfo()函数看到的页面上没找到mssql的相关信息,配置成功的话我记得应该能看到
难道是apache2.2的问题,我把PHP.INI放到c:\windows下面就可以了,我明明把环境变量PATH配置过了啊
而且2.0的时候我没把INI文件移动过也能正常使用啊,郁闷.....
