Current implementation of the rewrite router does not allow passing array parameters in the /{key}/{value} structure. This prevents creating nicely structured URL's from dynamic data.

Passing arrays can be easily implemented by changing line 174 in Zend_Controller_Router_Route_Module, from:

$params[$key] = $val;

To:

$params[$key] = (isset($params[$key]) ? (array_merge((array) $params[$key],array($val))): $val);

Which would create an array when the same parameter key is declared multiple times. I wrote a short article about this issue and explained in greater detail on: [http://techfounder.net/2008/06/…]
