[PHP] Profile section help
I'm currently making a XML Social Website as a project for school for my Final Exams which are in 1/2weeks.
(No Design, Only development needed)
These are the requirements:
*Login/Registration System [Done]
*Upload Profile Picture 
*Edit Profile Information (Email, Password, Name) [Done]
The next thing I need is a profile page (Example: profile.php?id=Laim)
However I've never done that before.. Even if it was when they signed up it generated a file for their profile which people could view (Laim.php/Jim.php etc)
Can anyone help me with this?
