Facebook recently updated their PHP-SDK to version 3.0 also added new way of authentication. This is a major change. So this is the updated post of my old popular post.

In this version of my code, I avoided javascript authentication, because that is cookie based and php sdk 3.0 has some conflicts with the old system. Facebook will also update the javascript sdk soon, so later you can use the login/logout system of javascript api with php sdk. But for now you should use fully php base authentication.

In this post you’ll learn:

    How to integrate Facebook Connect in your website
    How to generate Facebook Login / Logout URL
    How to get extended permissions from users

    How to run FQL Query
    Publish Wall Post using PHP
