simple php search facebook users and send message(repost)

I need the below to be written in php: 1. search for users in facebook by keyword (ideally by interest) - note: I assume this requires login to facebook first 2. send a message (customizable) to each of the found users. Thanks all. ## Deliverables There should be a status window to show the progress of the search. There should be a form or text fields to specify the keyword to search. There should be a form with text box to allow me to key in the message to be sent. There should be an option to specify the time interval (in minutes) in between sending each message (meaning send a message to first found user, pause for x minute(s), then send the same message to the second found user and so on....)
