Symfony3 deserialize multiple entity objects

Question

Serialize and deserialize single entity object work properly for me.

It is possible to serialize and deserialize multiple object (array of objects) in this way??

$notifications = $this->getDoctrine()
    ->getRepository('AppBundle:Notification')
    ->findAll();

$encoder = new JsonEncoder();
$normalizer = new ObjectNormalizer();

$serializer = new Serializer(array($normalizer), array($encoder));
$jsonContent = $serializer->serialize($notifications, 'json');

return new Response($jsonContent);

And

$response = curl_exec($ch); // my $jsonContent from previous code

$encoder = new JsonEncoder();
$normalizer = new ObjectNormalizer();

$serializer = new Serializer(array($normalizer), array($encoder));
$notifications = $serializer->deserialize($response, Notification::class, 'json');

Then i got:

The property path constructor needs a string or an instance of "Symfony\Component\PropertyAccess\PropertyPath". Got: "integer" 500 Internal Server Error - UnexpectedValueException

Will sounds stupid but the error message does tell you everything... Your property path constructor is waiting a an instance of PropertyPath, which is a child of PropertyAccess. But, your constructor get an Integer as parameter, which is obviously wrong. Can you add your construtor and everything related to it in your question plz? — Preciel

I found solution

use Symfony\Component\Serializer\Encoder\JsonEncoder;
use Symfony\Component\Serializer\Normalizer\ArrayDenormalizer;
use Symfony\Component\Serializer\Normalizer\GetSetMethodNormalizer;
use Symfony\Component\Serializer\Serializer;

$serializer = new Serializer(
    array(new GetSetMethodNormalizer(), new ArrayDenormalizer()),
    array(new JsonEncoder())
);

$data = ...; // The serialized data from the previous example
$persons = $serializer->deserialize($data, 'Acme\Person[]', 'json');
