session variables - change values?

[adrian_quah]

Hallo all,
I'm new to sessions. in my app, i'm using session to keep track of the logged-in user..I am wondering how we can change the value of the vars,
eg: $username, $password
once they've been assigned values..Is it possible?

Danke, gracias!

I think once you've registered a session variabled, it's basically like a super global variable.

session_register('username');

and then all you have to do is:

$username = "something else";

you might wanna use really different variable names for your session vars ($ses_username or something), so they don't get mixed up by variables in your other scripts.

Thanks sevex, yes, i think its a great idea to rename my session vars to like $sess_username 🙂

I'll try changing the value of session vars as u said just now, hope it goes well.

btw, when a person says global vars, it means for the context of the script or page, right? or does it mean (as u seem to indicate) to be preserved throughout the session?
