Use this demo to see the Facebook API tutorial code in action. If you click the "login" link on this page, the script will redirect you to Facebook for authorization. After you've authorized this Facebook App, your browser will redirect you back to this page. Remove this app after the test from your list of Facebook applications (optional).
This demo page will post the Facebook API tutorial link and the comment "A step by step tutorial on how to use the Facebook PHP SDK v4.0" to your Facebook timeline. Before this happens you need to authorize this post. I advice, to change your (default) Facebook privacy settings if you don't like to include the example post.
