The MoneyBundle provides support for serializing Money\Money instances using either the Symfony Serializer component or the JMS Serializer (note, the JMSSerializerBundle must be installed to enable the serialization handler for the JMS serializer).

Below is an example of building a JSON response in a controller using the Symfony Serializer:


namespace App\Controller\API;

use Money\Money;
use Symfony\Bundle\FrameworkBundle\Controller\AbstractController;
use Symfony\Component\HttpFoundation\JsonResponse;
use Symfony\Component\HttpFoundation\Request;
use Symfony\Component\Routing\Annotation\Route;

final class MoneyCalculatorController extends AbstractController
     * @Route("/api/money/add", name="app_api_add_money", methods={"POST"})
    public function apiAddValues(Request $request): JsonResponse
        $firstValue = $request->request->getInt('first_value');
        $secondValue = $request->request->getInt('second_value');

        $addedValues = Money::USD($firstValue)->add(Money::USD($secondValue));

        return $this->json($addedValues);

Below is an example of how a Money\Money instance is serialized into JSON format:

    "amount": "1000",
    "currency": "USD"
