----------

try this one instead. works fine in this some urls

https://youtube.com/watch?v={video_id}&param1={value}

https://youtube.com/watch?v={video_id}

$pattern = '%^(?:https?://)?(?:www.)?(?:youtu.be/|youtube.com(?:/embed/|/v/|/watch?v=))([\w-]{10,12})(?:\S+)$%x';

----------

%^(?:https?://)?(?:www.)?(?:youtu.be/|youtube.com(?:/embed/|/v/|/watch?v=))([\w-]{10,12})(?:\S+)$%x will not validate

http://www.youtube.com/watch?v=8F5VSKT38r0

correctly.

MATCH 1

----------

I add "https://" for the start of string

/^(http://|https://)(?:www.)?(?:youtube.com|youtu.be)/(?:watch?(?=.*v=([\w-]+))(?:\S+)?|([\w-]+))$/
