It still doesn't work :(... When I try to destroy the session without asking if there's a session_id, it gives me a warning, I fixed it with the if(session_id()) but still, when the user logs in again with a different profile, in the same browser window, the profile that is loaded is the previous one... Here I copy the logout.php code: <? $_SESSION['validlogin']=""; $_SESSION['username']=""; $_SESSION['password']=""; //destroy the sessions array $_SESSION = array(); //destroy the session if(session_id()){ session_destroy(); } ?> And the code that runs when the user logs in: <? $username=trim($_POST['user']); $password=trim($_POST['pwd']); if(session_id()){echo('Error, please contact tech support'); exit();} if(validateuser()){ session_start(); $_SESSION['validlogin']=true; $_SESSION['username']=$username; $_SESSION['password']=$password; } ... ?> Any ideas why the session variables get set to their first value after starting the session for the second time? Should I create a different session id each time?
