This is a snippet of route in ZF2 to handle url's like /controller/action, /controller/action/param1/value1, /controller/action/param1/value1/param2/value2...perhaps that's not the best way to do that but comming soon I would like to handle url's with undefined number of params with just one routing rule....

zf_route.php

<?php
//   ...the other options before.....
'home' => array(
                'type' => 'Zend\Mvc\Router\Http\Literal',
                'options' => array(
                    'route'    => '/',
                    'defaults' => array(
                        'controller' => 'Application\Controller\Index',
                        'action'     => 'index',
                    ),
                ),
            		'may_terminate' => true,
            		'child_routes' => array(
            				'default' => array(
            						'type'    => 'Segment',
            						'options' => array(
            								'route'    => '[:controller[/:action[/:key/:value[/:key/:value]]]]',
            								'constraints' => array(
            										'controller' => '[a-zA-Z][a-zA-Z0-9_-]*',
            										'action'     => '[a-zA-Z][a-zA-Z0-9_-]*',
            										'key'     	 => '[a-zA-Z][a-zA-Z0-9_-]+',
            										'value'      => '[a-zA-Z]*[a-zA-Z0-9_-]*[0-9]*',
            								),
            								'defaults' => array(
            								),
            						),
            				),
            				'query' => array(	'type' => 'Query',
            								),
            		),

            //  //   ...maybe the other options after.....
