Need Script To Integrate External Website With Facebook

I need a script written that will help integrate an external website with Facebook, utilizing the Open Graph API. ## Deliverables I need a script written that will help integrate an external website with Facebook, utilizing the Open Graph API. When a user visits my site, he/she is invited to Connect with my site using Facebook. Upon clicking the appropriate link, the user is asked for permission to post content on their Wall and their friends' Walls (publish_stream). Once permission is granted, the script will proceed to: 1. Direct the user to a url of my choice. 2. Post a status update on the user's Wall. 3. Posts to the Walls of several of the user's friends. 4. The script should also ask for permission for the user's email address (optional) and store it, so he or she can be contacted later. NOTE: I need to be able to edit the script so that the number of Wall postings on friends' Walls is determined by me. In addition, I want the script to randomly choose one message to post to a particular Wall out of several available that are either read from a text file or are entered into the script by me. Server runs PHP/MySQL The source code should not allow others to easily copy-paste the script.
