Youtube RegExp Compatible with preg_match_all

Hello people of vbulletin, I've decided it's time to learn some php and write a vbulletin plugin.

So far so good:

But I'm having trouble with getting a rexexp to work with preg_match_all()
I'm getting the dreaded

Quote:

"PHP Warning: preg_match_all(): Delimiter must not be alphanumeric or backslash"

When I use:

Code:

if (stripos($string, 'youtu') !== false)

{

$regex = 'https?:\/\/((.+\.youtube\.com\/watch\?v=)|(youtu\.be\/))([a-zA-Z0-9-_]+)';

preg_match_all($regex, $string, $matches);

if (!empty($matches))

{

     $og_array['og:video'] = $matches[2][0];

}

}

Any words of wisdom? TIA

Just as the error states: You don't have any valid delimiters for your expression in $regex. Try:

PHP Code:


		
			
$regex = "/https?:\/\/((.+\.youtube\.com\/watch\?v=)|(youtu\.be\/))([a-zA-Z0-9-_]+)/";

As well as /, vbulletin uses # as the delimiter as well.
