Good login script, need help to logout

[neizo]

Hello,

I use this files (working fine) to login and to create session in database.
I need help with the logout.php file.

How, to destroy this session?
How to clear the cookies?

[devinemke]

there is a good example on the [man]session_destroy[/man] man page

[neizo]

I try the first example but nothing happens.
If I click "back" from browser I can do anything in backend.

I have to delete the record (session) from database first?

[neizo]

here is my logout.php
please, just tell me if this is the right way.

<?
include ("session.inc.php");
session_start();
$_SESSION = array();
if (isset($_COOKIE[session_name()])) {
    setcookie(session_name(), '', time()-42000, '/');
}
session_unset();
session_destroy();
include("../inc/connect.php");
$result2 = mysql_query("DELETE FROM foo_sessions");
header( 'Location: index.php' ) ;
?>

Hello, any help please?
