------ Solution --------------------
Copy the dll file to system32 in win2008.
After modifying php. ini, remember to restart iis.
------ Solution --------------------
Phpinfo finds whether the File loaded by the load Configuration File is the same as the php. ini File you modified.

In addition, check that the php_mysql.dll file is in the/php/ext/directory.
