How do i logout and kill the session?

[bryanptcs]

Here is the code for my logout link:

[code]
<a href="logout.php">Logout</a>
[/code]

Here is logout.php:
[code]
<?php


header('http://www.giftfromgodcomputerfoundation.org');
session_destroy();
 


?>
[/code]

What i need it to do is logout the user and return them to the main page....

I get the following error:

Warning: session_destroy() [function.session-destroy]: Trying to destroy uninitialized session in /home/giftfrom/public_html/staff/logout.php on line 5

easier way

[code]
<?
session_start();
$_SESSION=array();
header('http://www.giftfromgodcomputerfoundation.org');
exit;
?>
[/code]

fyi: sessions must be started before its destroyed :-)

I also realized that it should have been...

header("Location: url");

instead of

header('url');

Thanks for you help.
