undefined function mysql_connect()

I am getting this error when I go to a PHP page on apache. It doesn't do that on abyss. I'm using PHP5, but I took the semicolon away from the mysql extension in php.ini. So what do I do?

You have to copy some files .dll to the system directory or apache directory.
It's probably only the files with mysql in them. you can read a tutorail (http://www.philbrodeur.com/tutorials/server2/) about it or... search the forum for the anwser :)

I copied to my apache directory and system32, but it still doesn't work. :confused:

Edit: Nevermind, forgot I had to restart the server.
