<?php

if ($signedRequestObject["page"]){
// this means this signed_request was generated on a page
if ($signedRequestObject["page"]["liked"]){
// the page was liked
}
}
//used functions
function parse_signed_request($signed_request, $secret) {
list($encoded_sig, $payload) = explode('.', $signed_request, 2);
