Add array to session Symfony2

Question

I try to add array of multiple vals to session var bu sending ajax request. I do this:

public function addFoodAction(Request $request)
{
    $foodId = json_decode($request->getContent(), true)['food'];
    $food = $this->getDoctrine()->getRepository('HackatonDinningRoomBundle:Food')->find($foodId);
    $arr = array();
    $arr[]=$food;
    $session = $this->get('session');
    $session->set('items', array($food));

    return new Response(count($arr));
}

How I can do that ?

I see some issues with your code but what are you expecting and what are you actually receiving? — Jason Roman

Use serialize:

$session->set('items', serialize(array($food)));

To retrieve the data:

unserialize($session->get('items'));

In addition to what @Gnucki said, I'd recommend using something other than the default serializer in php. Things like circular references can cause your program to crash. I'd recommend jms/serializer (but symfony/serializer works also).

echochamber is right, you should take a look at JMSSerializer if the serialized object is a bit complicated.
