There are two types of youtube link for one video:
Example:
$link1 = 'https://www.youtube.com/watch?v=NVcpJZJ60Ao';
$link2 = 'https://www.youtu.be/NVcpJZJ60Ao';
This function handles both:
function getYoutubeEmbedUrl($url)
{
$shortUrlRegex = '/youtu.be\/([a-zA-Z0-9_-]+)\??/i';
$longUrlRegex = '/youtube.com\/((?:embed)|(?:watch))((?:\?v\=)|(?:\/))([a-zA-Z0-9_-]+)/i';
if (preg_match($longUrlRegex, $url, $matches)) {
$youtube_id = $matches[count($matches) - 1];
}
if (preg_match($shortUrlRegex, $url, $matches)) {
$youtube_id = $matches[count($matches) - 1];
}
return 'https://www.youtube.com/embed/' . $youtube_id ;
}
The output of $link1 or $link2 would be the same :
$output1 = getYoutubeEmbedUrl($link1);
$output2 = getYoutubeEmbedUrl($link2);
// output for both: https://www.youtube.com/embed/NVcpJZJ60Ao
Now you can use the output in iframe!
