1) You will need an API key. Go to https://developers.google.com/ and log in or create an account, if necessary. After logging in go to this link https://console.developers.google.com/project and click on the blue CREATE PROJECT button. Wait a moment as Google prepares your project.

2) You will need a web host that is running PHP with file_get_content supported. You can check by creating a new script with just "echo php_info();" and verifying that allow_url_fopen is set to On. If it is not, then change the configuration or talk to your web host.

";
  //Replace This With The Video ID. You can get it from the URL.
  //ie https://www.youtube.com/XWuUdJo9ubM would be
  $sVideoId = "XWuUdJo9ubM";

  //Get The Video Details From The API.
  function getVideoDetails ($sVideoId) {
    global $sYouTubeApiKey;
    //Generate The API URL
    $sUrl = "https://www.googleapis.com/youtube/v3/videos?id=".$sVideoId."&key=".$sYouTubeApiKey."&part=contentDetails";
    //Perform The Request
    $sData = file_get_contents($sUrl);
    //Decode The JSON Response
    return json_decode($sData);
  }

  //Get The Video Duration In Seconds.
  function getVideoDuration ($sVideoId) {
    $oData = getVideoDetails($sVideoId);
    //Deal With No Videos In List
    if (count($oData->items) < 1) return false;
    //Get The First Video
    $oVideo = array_shift($oData->items);
    //Extract The Duration
    $sDuration = $oVideo->contentDetails->duration;
    //Use Regular Expression To Parse The Length
    $pFields = "'PT(?:([0-9]+)H)?(?:([0-9]+)M)?(?:([0-9]+)S)?'si";
    if (preg_match($pFields, $sDuration, $aMatch)) {
      //Add Up Hours, Minutes, and Seconds
      return $aMatch[1]*3600 + $aMatch[2]*60 + $aMatch[3];
    }
  }

  header("Content-Type: text/plain");
  $oData = getVideoDetails($sVideoId);
  print_r($oData);
  echo "Length: ".getVideoDuration($sVideoId);
?>

Hope this helps!
