You could try this:

PHP Code:


			
<?php
session_start();

// Your Code

session_unset();

if (session_id() !== "")
{
    session_destroy();
    // Session is destroyed!
} else {
    // There's no session to destroy!
}

header('Location: http://www.example.com');
?>

hi

session_unset â Free all session variables

So u already made free all session variables

And

session_unregister() just Unregister a global variable from the current session
