Preg_matche youtube id issue

Question

I'm working on a small php script. I have used preg_match to grab youtube id from a long text. Any way i'm using this code :

preg_match('~/v/([0-9a-z_]+)~i', $text, $matches)

The code work perfectly but he dont grab ids which containt "-".

Answer 1

You don't have a - in your regular expression, it should be:

preg_match('~/v/([0-9a-z_\-]+)~i', $text, $matches)
