Php-Apache + PHP + mysql configuration problems

I have configured both Apache and php. However, when connecting to the database, the Fatalerror: Calltoundefinedfunctionmysql _ connect () inF error occurs, and then check phpinfo (). The ConfigurationFile (php. ini) PathC: WINDOWSLoadedConfigurationFile (none); I'm sure it is already in the apache configuration file. Add PHPIniDir & quot; F: php & quot; and set it in php. ini mysqlphp.

Loaded Configuration File (none); I'm sure it is already in the apache Configuration File. Add PHPIniDir "F:/php" and enable php _ mysql. dll in php. ini. The/ext path is also set to normal.
Thank you for your guidance. Baidu has been trying the above methods for a long time ..
