How do I get a YouTube video thumbnail from the YouTube API?

Question

If I have a YouTube video URL, is there any way to use PHP and cURL to get the associated thumbnail from the YouTube API?

Answer 1

You can get the video ID from the YouTube video url using parse_url ,parse_str and then insert in to the predictive urls for images. Thanks to YouTube for the predictive URLs

$videoUrl = "https://www.youtube.com/watch?v=8zy7wGbQgfw";
parse_str( parse_url( $videoUrl, PHP_URL_QUERY ), $my_array_of_vars );
$ytID = $my_array_of_vars['v']; //gets video ID

print "https://img.youtube.com/vi/$ytID/maxresdefault.jpg";
print "https://img.youtube.com/vi/$ytID/mqdefault.jpg";
print "https://img.youtube.com/vi/$ytID/hqdefault.jpg";
