I'm essentially trying to duplicate what happens when you use  in a url, something like: page.php?type=1&type=2, etc.
Right now, I have this:
$routes->add("/read/(([0-9],?)+)", array( 'controller' => 'read', 'action' => 'index', 'type' => 1 ));
Then I can explode the types on the ',', but that just seems clunky to me. Is there a better way to do this? I want users to be able to bookmark searches.
