Getting started with the Facebook SDK for PHP

Alright, it is time for some code.

require_once 'sdk/autoload.php';

use Facebook\FacebookSession;
use Facebook\FacebookRedirectLoginHelper;
use Facebook\FacebookRequest;
use Facebook\FacebookResponse;
use Facebook\FacebookSDKException;
use Facebook\FacebookRequestException;
use Facebook\FacebookAuthorizationException;
use Facebook\GraphObject;

FacebookSession::setDefaultApplication('API_KEY', 'API_SECRET');

/*
 * login helper with redirect_uri
 * make sure you have added the redirect uri to oauth list in your app
 */
$helper = new FacebookRedirectLoginHelper( 'http://example.com/push.php' );

// see if a existing session exists
if ( isset( $_SESSION ) && isset( $_SESSION['fb_token'] ) ) {
    // create new session from saved access_token
    $session = new FacebookSession( $_SESSION['fb_token'] );

    // validate the access_token to make sure it's still valid
    try {
        if ( !$session->validate() ) {
            $session = null;
        }
    } catch ( Exception $e ) {
        // catch any exceptions
        $session = null;
    }
}

if ( !isset( $session ) || $session === null ) {
    // no session exists

    try {
        $session = $helper->getSessionFromRedirect();
    } catch( FacebookRequestException $ex ) {
        // When Facebook returns an error
        // handle this better in production code
        print_r( $ex );
    } catch( Exception $ex ) {
