EDIT:
I see that you have tried ctype_alnum() and it didnt work. Most probably you have to do a:

setlocale(LC_CTYPE, 'C'); 

before you use ctype_alnum()

just out of curisoty so i know whats going on in my code, what does that line do?

on more thing is, i want to host my mysql database on a seperate server, which i have one kind of, except it won't connect
don't i just type the IP address of the server wiht mysql on it? ie now i type in localhost because the web and mysql servers are on the same machine

It switches the locale to the 'C' locale, which is fairly language-neutral. (Or rather, language-ignorant - it has absolutely no proper treatment of anything outside English.)
