    try{

        include_once ('.\facebook-php-sdk-master\src\facebook.php');

    }

    catch(Exception $o){

 

        print_r($o);

 

    }

    $facebook = new Facebook(array(

      'appId'  => $fbconfig['appid'],

      'secret' => $fbconfig['secret'],

      'cookie' => true,

    ));

 

    $user       = $facebook->getUser();

    $loginUrl   = $facebook->getLoginUrl(

            array(

                'scope'         => 'email'

            )

    );

 

    if ($user) {

      try {

        $access_token = $facebook->getAccessToken();

      } catch (FacebookApiException $e) {

        d($e); 

        $user = null;

      }

    }

 

    if (!$user) {

        echo "<script type='text/javascript'>top.location.href = '$loginUrl';</script>";

        exit;

    }

 

    $total_friends = count($user_friends['data']);

    echo 'Total friends: '.$total_friends.'.<br />';

    $start = 0;

    while ($start < $total_friends) {

        echo $user_friends['data'][$start]['name'];
