（请教高手）php无法加载mysql相关的扩展

[爱着有你]

我的apche是2.2.8，PHP是5.2.5.
打开了下面的三个扩展，
extension=php_mysql.dll
extension=php_pdo.dll
extension=php_pdo_mysql.dll
apache的error.log中的异常信息如下：


PHP Warning: PHP Startup: Unable to load dynamic library 'D:\\devsoft\\php5.2.5\\ext\\php_mysql.dll' - \xd5\xd2\xb2\xbb\xb5\xbd\xd6\xb8\xb6\xa8\xb5\xc4\xc4\xa3\xbf\xe9\xa1\xa3\r\n in Unknown on line 0

只有这么分了，分少点。先谢过了

那些文件还要放到c:\windows\system32下面

如果用的是win系统，用环境变量方式安装，设置一下路径，就不用拷了，网上搜搜

谢谢，我今天来了以后就好了。我也不知道是怎么回事。可能是服务器加载有延迟，或者是浏览器的缓存吧。不过我清理过浏览器的缓存的。不过还是要谢谢二位了。
