is there something wrong with session_destroy(); ???

 

also for the cookies, set a expire past the current time:

 

setcookie("username","", time()-3600);

ehh...  session_destroy();??? i dont understand

[revraz]

To end a session just do

 

session_start();

session_destroy();

[zuko]

where i should put that? in which line?

On your logout page.

 

Just create a page called logout.php and write the following in it:

 

session_start();
session_destroy();
header('Location: login.php'); //change this to suit your needs
