Regexp with parentheses

I have a string containing some numbers like this:

$list = "(1)(12)(3)"
or
$list = "(4)";

and I want to get the numbers out like this

$results[0] = "1";
$results[1] = "12";
$results[2] = "3";

or in the second example above:

$results[0] = "4"

I can't for the life of me come up with a regexp to do this.

Can anyone assist?

Thanks
Richard

/(([0-9]+))/

I think that will work. Escape the opening ( then look for the numbers 0-9 one or many times then escape the closing ).

so in php you'd do:

preg_match("/(([0-9]+))/", $pattern, $matches);

And $matches[1] should hold all of the numbers that you are looking for.

$list = "(1)(12)(3)";

preg_match_all("/$(\d+)$/U", $list, $matches);

echo "<pre>";
print_r($matches[1]);

Oh god, I think you're wonderful! That absolutely fits the bill

Plus I'd never come across the "print_r()" function before... ;-)

Thanks to all for the tips!
