I thought I would share with you all a tutorial I just posted on creating a Facebook app using the Facebook Graph API and their PHP SDK. It's a very easy to follow tutorial and by the end you'll have your own app reading and writing posts to your wall as well and displaying photos from your ablums and posting photos to an album. Enjoy:
