PHP → How to take a YouTube Video from Facebook Graph API and convert it to an embed HTML 5 YouTube player

So when you use the Graph API from Facebook you get a JSON return something similar to this:

{
 “data”: [
 {
   “source”: “http://www.youtube.com/v/AeFHAttQuIY?autohide=1&version=3&autoplay=1", 
   “type”: “video”, 
   “message”: “Did you know? You can leave your limits with the #LamboHuracan on #ForzaHorizon2 for Xbox!”, 
   “full_picture”: “https://fbexternal-a.akamaihd.net/safe_image.php?d=AQDFKEuzZdwRbNta&bust=1&url=https%3A%2F%2Ffbcdn-sphotos-g-a.akamaihd.net%2Fhphotos-ak-xpa1%2Ft31.0-8%2Fs720x720%2F10838171_1056779374347682_8775251615557532677_o.png", 
   “id”: “227228333969461_1056779801014306", 
   “created_time”: “2015–01–06T16:00:03+0000", 
   “likes”: {
     “data”: [
     {
     “id”: “527943903982238", 
     “name”: “Akki Doddamani”
     }
     ], 
   “paging”: {
   “cursors”: {
   “after”: “NTI3OTQzOTAzOTgyMjM4", 
   “before”: “NTI3OTQzOTAzOTgyMjM4"
   }, 
   “next”:   “https://graph.facebook.com/v2.2/227228333969461_1056779801014306/likes?limit=1&summary=true&after=NTI3OTQzOTAzOTgyMjM4"
 }, 
   “summary”: {
   “total_count”: 1147
   }
  }
 },

Then you can simply look for the type that is being posted, if its a video AND a YouTube video, you can use the following code to get the ID and then inject it into a iFrame for the HTML 5 YouTube Video Player.

//NOTE : $data is the data property from the JSON file after it has been JSON decoded.

<?php
 if($data['type']=='video') {
  if (preg_match('/youtube/i', $data['source'])) {
   //Get YT ID
   $start = strpos($data['source'], '/v/');
   $end = strpos($data['source'], '?');
   $length = $end - $start;
   $yt_id = substr($data['source'], $start, $length);
   $yt_id = explode('/v/', $yt_id);
   $yt_id = $yt_id[1];
   ?>
