Answer 1

Here is how I logout using the latest PHP-SDK:

login.php

require_once("php-sdk/facebook.php");

// Create our Application instance (replace this with your appId and secret).
$facebook = new Facebook(array(
  'appId'  => 'xxx',
  'secret' => 'xxx',
));

// Get User ID
$user = $facebook->getUser();

// We may or may not have this data based on whether the user is logged in.
//
// If we have a $user id here, it means we know the user is logged into
// Facebook, but we don't know if the access token is valid. An access
// token is invalid if the user logged out of Facebook.

if ($user) {
  try {
    // Proceed knowing you have a logged in user who's authenticated.
    $user_profile = $facebook->api('/me');
  } catch (FacebookApiException $e) {
    error_log($e);
    $user = null;
  }
}

// Login or logout url will be needed depending on current user state.
if ($user) {
    $logout_params = array('next'=>'http://www.pittsburghpartycentral.com/logout.php');
  $logoutUrl = $facebook->getLogoutUrl($logout_params);
} else {
    $login_params = array(
                        'scope' => 'email',
                        'display' => 'popup'
                        );
  $loginUrl = $facebook->getLoginUrl($login_params);
}

// This call will always work since we are fetching public data.
$naitik = $facebook->api('/naitik');

?>
