unset($_SESSION['session_var']); 

// destroy the Session, not just the data stored!
session_destroy();

// delete the session contents, but keep the session_id and name:
session_unset();

应该这样做：

unset($_SESSION['page']);

Answer 3

You wouldn't be deleting the session in this case, only the session variable. So just do:

unset($_SESSION['page']);
