I have the following script which will allow a user to login to my website using their facebook account, request the appropriate permissions, and if accepted, it will post a message on a wall:

<?php
    require 'facebook.php';

    $facebook = new Facebook(array(
        'appId'  => 'removed for security reasons',
    'secret' => 'removed for security reasons',
        'cookie' => true,
    ));

    $session = $facebook->getSession();

    if ($session) {

        if (isset($_GET[id])) {
            $post = $facebook->api("/" . $_GET['id'] . "/feed", "POST",  array('message' => 'Hello!'));
            echo 'A message has been posted on your friends wall';

        } else {

            $friends = $facebook->api('/me/friends');

            foreach ($friends as $key=>$value) {
                echo 'You have ' . count($value) . ' friends<br />';

                foreach ($value as $fkey=>$fvalue) {
                    echo 'friend id = ' . $fvalue[id] . ' - friend name = ' . $fvalue[name] . ' - <a href="/stage0.php?id=' . $fvalue[id] . '">post message</a><br />';
                }
            }
        }

    } else {

        $loginUrl = $facebook->getLoginUrl(array(
            'req_perms' => 'publish_stream',
            'next' => 'http://'.$_SERVER['SERVER_NAME'].'/stage0.php',
            'cancel_url' => 'http://'.$_SERVER['SERVER_NAME'].'/cancel.php',
        ));

        header('Location: '.$loginUrl);
    }
?>

I then have the following script to log the user out:

<?php
    error_reporting( E_ALL | E_STRICT );
    ini_set('display_errors', 1);
?>

<?php
    session_start();
?>

<html>
    <head>
        <title></title>

        <?php
            $_SESSION = array(); 
            session_destroy();
        ?>

        <meta http-equiv="refresh" content="0;index.php">
    </head>

    <body>
        <h1>logout</h1>
    </body>
</html>

This clears the sessions I created, but it does not log them out of facebook at all. How do I clear the sessions I create and also log them out of facebook?

    Recommended way to log out a user from both your application and Facebook, is to call the logout feature of the javascript SDK.

    <a href="/auth/logout" onclick="FB.logout();">logout</a>

    check : http://developers.facebook.com/docs/reference/javascript/FB.logout/
