How to encoder Csv with Symfony

I'm using serializer component's symfony, and there was an example to serialize and Object to JSON format, next:

$encoders = array(new XmlEncoder(), new JsonEncoder());
$normalizers = array(new ObjectNormalizer());

$person = new \AppBundle\Entity\Person();

// return new JsonResponse($person); // empty

$serializer = new Serializer($normalizers, $encoders);

* 1 param - object to be serialized

CSV and YAML encoder were added since Symfony 3.2

// instantiation, when using it as a component
use Symfony\Component\Serializer\Serializer;
use Symfony\Component\Serializer\Encoder\CsvEncoder;
use Symfony\Component\Serializer\Normalizer\ObjectNormalizer;

$serializer = new Serializer([new ObjectNormalizer()], [new CsvEncoder()]);

// instantiation, when using it inside the Symfony framework
$serializer = $container->get('serializer');

// encoding contents in CSV format
$serializer->encode($data, 'csv');

// decoding CSV contents
$data = $serializer->decode(file_get_contents('data.csv'), 'csv');
