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

Answer 1

Found this solution on github: Check if youtube video exists

Easy to use:

$headers = get_headers('http://www.youtube.com/oembed?url=http://www.youtube.com/watch?v=nonexistingid');

if (!strpos($headers[0], '200')) {
    echo "The YouTube video you entered does not exist";
}

Working fine.
