Normalizers turn objects into arrays and vice versa. They implement NormalizerInterface for normalizing (object to array) and DenormalizerInterface for denormalizing (array to object).

use Symfony\Component\Serializer\Serializer;

$normalizers = [new ObjectNormalizer()];
$serializer = new Serializer($normalizers);
