I've followed the instructions on http://developers.facebook.com/docs/api#authorization using the standard PHP library. Everything works fine until it redirects to my site. I'm not sure what I'm meant to be doing here! When the redirection occurs, I can see the key facebook talks about that I use to request an OAuth token in the URL. However what am I meant to do with this? Do I write a simple script that takes the new 'code' value and place a request to the facebook page with that included in the details? Is there no call in the php library to do this entire process for me? Any help appreciated.
