Return array from symfony 2 controller action

Question

I need to return $items array from 'http://localhost:8000/cart/viewall'
controller action. But all i get is this error.

The Response content must be a string or object implementing __toString(), "array" given.

This is my code,

 /**
 * @Route("/cart/viewall")
 * @Template()
 */
public function viewallAction() {
    $items = array(1 => 'item 1', 2 => 'item 2');        
    return new Response($items);
}

It would be great help if someone can supply a solution.

new JsonResponse($items); and you have to use the good use ....\JsonResponse; — anotherdev

What do you mean with "I need to return an array"? The controller in Symfony is responsible to return a response and since an HTTP response contains a body which is just a string your response must contain a string to. Do you maybe mean you want to return a JSON encoded array? — xabbuh

Think about the new Response like a call to echo. This is a response to the browser and it has to be a string. — Al.G.

Use JsonResponse instead.

Example :

$items = array(1 => 'item 1', 2 => 'item 2');
return new JsonResponse($items);

see http://symfony.com/doc/current/components/http_foundation/introduction.html
