I got the following error
Warning: session_destroy(): Trying to destroy uninitialized session in /home/alvinsh/public_html/istudies/logout.php on line 9
here is my log out code:
<?php
session_start();
$old_user = @$HTTP_SESSION_VARS['valid_user']; // store to test if they were logged in
unset($HTTP_SESSION_VARS['valid_user']);
session_destroy();
$old_admin = @$HTTP_SESSION_VARS['admin_user']; // store to test if they were logged in
unset($HTTP_SESSION_VARS['admin_user']);
session_destroy();
?>
<html>
<body>
<h1 align="center">Log out</h1>
<?php
if (!empty($old_user))
{
echo '<div align="center">Logged out.</div><br />';
}
else
{
// if they weren't logged in but came to this page somehow
echo '<div align="center">You were not logged in, and so have not been logged out.</div><br />';
}
?>
<div align="center"></div>
