cant connect to mysql databases using php

i have php5 mysql4.0.2 and apache2.0.5 installed on my windows xp. mysql on its own works fine. php works with the apache server fine too. for some reaseon my php doesnt recognize any of the mysql functions.
when i run phpinfo there is no mysql info box there but there is a "sqlite" one. i tried installing everything from scratch but it just wont work.

any ideas??

You have to compile PHP "with-mysql"

how do i do it under XP?

no clue, never used win32 as a webserver. I suggest googling for a combo PHP/Apache program.

problem solved:
php 5.0.0 doesnt come with a built in support for mysql
installed php 4.3.8 and everything works fine.
