I just started making an application for Facebook, however I ran into problem early on. The first step I want people to do is to give permission to access their profile. All over the web are examples of how to do this with:

$user_id = $facebook->require_login();

However, this is the way it works using the Old PHP API. I have downloaded and installed the new one in my application folder and it is not working anymore.

My question is (and i really have been searching for an answer for a long time) what is the code to do this with the new API?

(and related question: is it better to use the old API, or learn to work with the new one when I am just starting making apps right now)

I have this code now;

 <?php
    // Awesome Facebook Application
    //
    // Name: -
    //

    require_once 'facebook-php-sdk/src/facebook.php';

    // Create our Application instance.
$facebook = new Facebook(array(
        'appId' => $app_id,
        'secret' => $app_secret,
        'cookie' => true
));

$loginUrl = $facebook->getLoginUrl(array(
    'req_perms' => 'email,user_birthday,publish_stream,sms,status_update,user_location'
));

echo "<p>hello, <fb:name uid=\"$user_id\" useyou=\"false\" />!</p>";
