Clean the code and optimize standard framework route.

Testing 10000 matches of:

$route = new Zend_Controller_Router_Route('archives/:year/:month/*', array('controller' => 'archive'));

for ($i = 1; $i <= 10000; $i++) {
    $values = $route->match('archives/2006/' . $i . '/controller/test/year/' . $i . '/sort/author');
}

Before refactoring: Test took: 0.6967 Test took: 0.6868 Test took: 0.7009 Test took: 0.6913 Test took: 0.6931 = 3,4688 s

After first: Test took: 0.5861 Test took: 0.5835 Test took: 0.5802 Test took: 0.5799 Test took: 0.5826 = 2.9123 s

Approx 20% gain.
