preg_match() always returns the text that matched the entire pattern as the
first element of the $match array. So the only way to have a match array
that contains just the numbers that match your current parenthesized
subpattern is to have an entire pattern that matches just those numbers from
the string. Which I don't think you can do.

Why do you want to do this?
