Serialize Doctrine object without references

[matiux]

I took two objects in this way:

$users                      = $this->userRepo->findAll();

So, $users is an array of two User Object that in the schema have some references to another objects.
When I serialize the array:

$users =                    $this->serializer->serialize($users, 'json');
echo $users;

I obtain the json rapresentation of the whole object with all its references. Is there a way to limit the depth of serialization?

Thanks
