Be aware which structure of data you are using, try code below, is working for me.
Please check if link https://webstickers.000webhostapp.com/ytb-dl.php is active.
$content = file_get_contents('https://webstickers.000webhostapp.com/ytb-dl.php');
$json_output = json_decode($content, true);
foreach ($json_output['streamingData'] as $formats) {
if (!is_array($formats)) {
continue;
}
foreach ($formats as $format) {
echo $format['url'] . PHP_EOL;
}
}
