Thanks guys. I'm getting more and more into OOP.

At the moment I'm wondering if it's better do do something like this:

Create a Login class and a User class. First the user logs in via the Login class. If succesfully logins, the Login class creates a User class with the id of the user f.e. like $pUser = new User(1);. Then the Login class puts the User class in a session.

Shouldn't this be more logically (while thinking OOP)? Or am I just lost again? :-p
