[php]php连mysql出错：Calltoundefinedfunctionmysql_connect()

extension_dir = - The extension_dir needs to point to the directory where PHP extensions files are stored. The path can be absolute (i.e. "C:\PHP\ext") or relative (i.e. ".\ext"). Extensions that are listed lower in the php.ini file need to be located in the extension_dir.

应该改为

extension_dir = "c:/php/ext"
