the link taltk asbout installing via yum but you only has php support for 5.16 I installed the latest php version 5.2.17
I think the extensions directory you mention is only from a windows box my php.ini file doesnt contain the word extensions, it might exist if i can find out how to install php5.2.17 without using yum

see if phpinfo() shows you the MySql module details. if not, that means MySql is not loaded and/or compiled properly.
Try recompiling PHP and make sure it completes without any critical errors.
You can also, install Apache, PHP and MySql from RPMs which would save you the hassle of going through issues like this.
