yt.php?id=your-id

I would do like this the first 3 videos with sound
$stream=$streamin_data_json["streamingData"]["formats"][0];
if (isset($stream["cipher"])) {
parse_str($stream["cipher"],$dturl);
echo 'Download '.quality($stream["itag"]).'
';
}else{
echo 'Download '.quality($stream["itag"]).'
';
}

Replace with
foreach ($streamin_data_json["streamingData"]["formats"] as $stream) {
if (isset($stream["cipher"])) {
parse_str($stream["cipher"],$dturl);
print_r($dturl);
echo 'Download '.quality($stream["itag"]).'
';
}else{
echo 'Download '.quality($stream["itag"]).'
';
}

please contact me:

Awesome script!

Hi
two days ago code warked perfect, but now do not working at all.
Can you check it and fix it?

It's still working on php7. You should try checking your dpkg log on the server for any updates that may have changed your configuration.
