how to check or declare array values of an array like an instanceof a Class/Entity

In my symfony project I have an array $productContainer with some values like (php dump):

array:2 [▼
  0 => "value1"
  1 => "value2"
]

I pass this array in the Product entity by findBy method in my controller like this:

$products = $this->getDoctrine()->getRepository('MyBundle:Product')
                                ->findByValue($productContainer);

The results between the findBy method and the array values match very well.

But when I check if the array is an instance of my class Product like this:

dump($products instanceof Product);
die;

it retuns me : false

I understand that $products is an array and not an object, but how can I declare my array $products as an instanceof Product entity ?

Edit

In order to be more precise, I need to declare or check if my values of array $products are instanceof Product because in the same controller, I have to pass array $products in a queryBuilder for another entity like this:

$entity = $this->getDoctrine()->getRepository('MyBundle:Entity')
                              ->getEntityWithProducts($slug, $products);

I recover the array $products by a $_POST method (Request $request) Its a controller method that I retun into JsonResponse, that why I proceed in that way.

Arrays can't be of some object class, but if I understand what you want to do, maybe you can try using array functions.

Try this

$test = array_reduce(
          $products, 
          function ($condition, $item) {
            return $condition && $item instanceof Product;
          }, 
          true
        );
// $test will be true if all elements of $products are instances 
// of 'Product', false otherwise

Try findOneByValue instead findByValue if you need just one product.
Or extract some one element from your received array, because you receive array of entities after invoking findByValue.
Or traverse all elements in received array to check them.
Or maybe in your product repository present method findByValue that do some staff for you.

But anyway it sounds strange to check after doctrine that it returns for you appropriate class instance...
If you use something like getArrayResult you'll receive array, otherwise you'll receive instance of appropriate entity.
