推荐答案

如果使用:

http://github.com/facebook/php-sdk

您可以执行以下操作:

    $facebook = new facebook();
    $fbSession = $facebook ->getSession();

    //IF user is logged in
    if ($fbSession)
    {
        $_SESSION['fbsession'] = json_encode($fbSession);
    }
     else
    {
        header('Location: '.$facebook->getLoginUrl());
    }
