Managing YouTube with Google Data API

The Copy YouTube Playlists tool uses Google Data API (PHP) and YouTube API (v3) to clone any public YouTube playlist into the YouTube account of the authorized user.

You need to create your own OAuth2 secret keys from the Google Developer’s Console and also the redirect URL should point to the page where the PHP script is hosted.


    require_once 'php-google-api-client/src/Google_Client.php';
    require_once 'php-google-api-client/src/Google_YouTubeService.php';


    $OAUTH2_CLIENT_ID = '';
    $OAUTH2_CLIENT_SECRET = 'labnol';

    $redirect = "";

    $client = new Google_Client();

    $youtube = new Google_YoutubeService($client);

    if (isset($_GET['code'])) {

        if (strval($_SESSION['state']) !== strval($_GET['state'])) {
            die('The session state did not match.');

        $_SESSION['token'] = $client->getAccessToken();
        header('Location: ' . $redirect);


    if (isset($_SESSION['token'])) {

    if ($client->getAccessToken()) {

            try {

                if ( preg_match('/(PL[A-Za-z0-9_-]+)/', $_POST["url"], $match) ) {

                    $plID = $match[0];
                    $pl_options = array ("id" => $plID, "maxResults" => 1);
                    $playlistDetails = $youtube->playlists->listPlaylists("snippet", $pl_options);

                    if ( $playlistDetails["pageInfo"]["totalResults"] == 1 ) {

                        $options = array ("playlistId" => $plID, "maxResults" => 50);
                        $videos = "";

                        do {

                            $playlist = $youtube->playlistItems->listPlaylistItems("snippet", $options);
                            $nextPageToken = $playlist["nextPageToken"];
                            $options["pageToken"] = $nextPageToken;

                            foreach ($playlist["items"] as $playlistItem) {
                                $videos .=  $playlistItem["snippet"]["resourceId"]["videoId"] . "#";

                        } while ($nextPageToken);

                        $youTubePlaylist = new Google_Playlist();

                        $playlistResponse = $youtube->playlists->insert('snippet,status', $youTubePlaylist, array());

                        $ids = explode ( "#", $videos ) ;

                        for ($i=0; $i<count($ids); $i++) {
