Very simple Facebook Open Graph single page website

This project is for a simple page, that when loaded, presents a random sentence (retrieved from a flat text file) and then allows the visitor to post this phrase as a status update on Facebook with a click of the button. If the user doesn't like it, a secondary button will cause the page to reload with a new sentence. Obviously, the user has to grant the necessary permissions to the application to write to his status. The application will also ask for the user's e-mail address (optional) and store it, so he or she can be contacted later. Notes: - The server runs PHP/MySQL. - Requires the use of the latest Graph API. - The source code shouldn't reveal the flat text file or allow others to easily copy-paste the script. - This project doesn't require a front-end design, just a basic CSS file that can be edited.
