Symfony Request: setController, setAction, setModule - php

Question

In zf2 I have the option to make fake requests with a Zend/Request object. Thus I can do an internal Request. I want to execute a part of my site with a few data. Thus, I must use a Controller, Module and a Action.
How would I do that?
Here's a snippet of code from zf2 from a previous question:
/application/controller/IndexController.php
<?php
class IndexController extends Zend_Controller_Action
{
public function init(){}
public function indexAction()
{
//process some data from $_GET, $_POST, maybe (via framework, ofc).
}
}
/public/index2.php
<?php
//--cut--
$application->bootstrap();
$options = array(
'action' => 'index',
'controller' => 'index',
'module' => 'default'
);
if( isset($options['action'], $options['module'], $options['controller']) )
{
//*
$request = new Zend_Controller_Request_Http ();
$request->setModuleName($options['module'])->setActionName($options['action'])->setControllerName($options['controller']);
$frontController = Zend_Controller_Front::getInstance ()->returnResponse ( true );
//*/
$response = new Zend_Controller_Response_Http ();
$frontController->getDispatcher ()->dispatch ( $request, $response );
var_dump($response);
}
Thank you!
