You've already got the problem solved but I see no reason to waste time and energy when it's not necessary. Is there any reason why the following would not suffice?

PHP Code:


			
$hash = 'abc123,1';
if (preg_match('/\d{1,3}/', $hash, $matches))
{
    $bits = (int) $matches[0];
    $hex  = $bits / 4;
    unset ($matches);
}
