PHP5 + Mysql5 + Apache 2.0.55

Hi all. I'm trying to set up mysql 5 with php 5 on my windows machine, but I can't get work it. Also I can't see any loaded extensions with phpinfo(). I have set extensions directory in php.ini, PATH dir in windows, what else I may to do? I used linux a lot of time and now I cant remember how to set up these things on windows :) thanks, depi
