title: Get all video informaion from playlist in YouTube API v3
body: <p>I have problem with getting the information of playlist in YouuTbe by API v3.<br>
  I just need to pass JSON to value.<br>
  I tried this in v2 but it's not working and also I don't know how I can use v3 code or what is the link that I can get the JSON from it.</p>
  
  <pre><code>$playlist_id = "AD954BCB770DB285";
  $url = "https://gdata.youtube.com/feeds/api/playlists/".$playlist_id."?v=2&amp;alt=json";
  $data = json_decode(file_get_contents($url),true);
  echo  $data;
  </code></pre>
