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??

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

You should be aware if you use the buildin MySQL of PHP you don't get the support for the installed version of MySQL but the version that comes with PHP.
This might come with the disadavantage of limited functionality of an older version and problems if you rely on new functions of MySQL.
