log out user settings

[matanzas]

If I create a link (as below) to log out a user I understand that there must be a session_start();

Do I have to change any of the unset $_SESSION settings?

<?php
// *** Logout the current user.
$logoutGoTo = "/interview/logout.htm";
session_start();
unset($_SESSION['MM_Username']);
unset($_SESSION['MM_UserGroup']);
if ($logoutGoTo != "") {header("Location: $logoutGoTo");
session_unregister('MM_Username');
session_unregister('MM_UserGroup');

exit;
}
?>

Thanks

Yes.

Don't use session_unregister().

[tt]session_unregister('MM_Username');[/tt]

is the same as

[tt]unset($_SESSION['MM_Username']);[/tt]

and the PHP online manual recommends against using session_unregister().

Thanks, I'll just delete
session_unregister('MM_Username');
and
session_unregister('MM_UserGroup');
