Facebook update via HTTP request sent to PHP web page

I have an iPhone App which the client authenticates with Facebook on the iPhone. This authentication could be via a desktop app. Either way the result is there is a SessionKey and a UserID that can be passed to via an HTTP request to PHP script. The HTTP request also passes the informational text, and/or images to be posted to the feed. The PHP script, using these parameters, and a Facebook AppAPIKey & AppSecret, publishes to the user's Facebook feed. You write code in PHP (or other language, Python, Drupal, Javascript?) that publishes to the Facebook user's feed. I will provide you the host web server and domain to test the project. Do not bid on this project unless you know how to do this project, and can complete it (quickly). Thank you.
