Posting to FaceBook feed using Graph API

Graph API was announced at F8 with a promise to dramatically simplify the FB API. I checked the read access over the new interface during the presentations and to my big surprise it worked flawlessly and from the first time. When I tried https://graph.facebook.com/facebook , JSON-formatted info about the FaceBook page was returned (as expected). Then I tried OAuth 2.0 way of accessing the API to post a message to the feed. And to my even bigger surprise it worked too! Here is what you need to do to access Graph API over OAuth: 1. Create a FB app, store app properties to a file: $appkey = '7925873fbfb5347e571744515a9d2804' ; $appsecret = 'THE SECRET' ; $canvas = 'http://apps.facebook.com/graphapi/' ; 2. Create a page that will prompt user the access permission (I am prompting for the publish_stream and offline_access permissions at the same time) //http://apps.facebook.com/graphapi/ require 'settings.php' ; $url = "https://graph
