How to check for broken links on YouTube videos?

Question

YouTube

Greetings
There are a lot of videos from video hosting sites on the site. Some of them exist, and some do not, have been removed or are not available. How can you check the availability of videos to do something with them - remove them from the code, for example? Maybe there are some programs or scripts? Checking manually is a long, unreasonable process, and over time, some of the videos may become inaccessible. How to automate the process?

More or less like this:

$url = 'http://www.youtube.com/get_video_info';

$params = [
    'video_id' => '{%YOUTUBE_VIDEO_ID%}',
];

$response = file_get_contents($url . '?' . http_build_query($params));

// www.youtube.com/get_video_info?video_id={%YOUTUBE_VIDEO_ID%}

parse_str($response, $response);

switch ($response['status']) {
    case 'ok':
        echo 'OK';
    break;
    case 'fail':
        echo 'FAIL';
    break;
    default:
        echo 'UNKNOWN';
}
