im using php and mysql

i have a problem, once the session destroyed after logging out, still some of the url can be still accessed. like adding customer and adding orders. but others cannot be accessed.


heres my logout.php

PHP Code:
<?php
session_start();
session_unset();
session_destroy();
$_SESSION = array();

$printout="<font color='green' size='2' face='arial'><center><b>Thank you for using SOMS.<br>Have a nice day!</b></center></font>";

    include("login.php");

?>
