How do I check if a video exists on YouTube, using PHP?

Answer 1

I used the YouTube API for checking if a video exists on You Tube. I downloaded the Google API Client Library for PHP. I used the following function:

/**
* Used to check if the given movie is availabe on youtube
*
* It uses youtube api and checks if given movie is available on youtube
* If a movie is not available then it returns false
*
* @param string $youtube_video_url the youtube movie url
*
* @return boolean $is_available indicates if the given video is available on youtube
*/
private function IsMovieAvailable($youtube_video_url)
{
    /** The autoload.php file is included */
    include_once("autoload.php");

    /** Is available is set to false */
    $is_available = false;

    /** The youtube video id is extracted */
    $video_id = str_replace("https://www.youtube.com/watch?v=", "",   $youtube_video_url);

   $DEVELOPER_KEY = $google_api_key;
   $client = new \Google_Client();
   $client->setDeveloperKey($DEVELOPER_KEY);

   // Define an object that will be used to make all API requests.
   $youtube = new \Google_Service_YouTube($client);

   // Call the search.list method to retrieve results matching the specified
   // query term.
   $searchResponse = $youtube->videos->listVideos('status', array('id' => $video_id));

   /** Each item in the search results is checked */
   foreach ($searchResponse['items'] as $video) {
       /** If the video id matches the given id then function returns true  */
       if ($video['id'] == $video_id) {
           $is_available = true;
           break;
       }
    }
    return $is_available;
}
