php-symfonyHow to create a REST API with PHP Symfony?

Creating a REST API with PHP Symfony is a straightforward process.

First, create a new Symfony project:

composer create-project symfony/website-skeleton my_project

Then, install the necessary packages:

composer require symfony/webpack-encore-pack
composer require symfony/maker-bundle --dev

Next, create the controller and routes for the API:

php bin/console make:controller

Then, create the model and repository for the API:

php bin/console make:entity

Finally, configure the serializer to return the data in the desired format:

use Symfony\Component\Serializer\Serializer;
use Symfony\Component\Serializer\Encoder\JsonEncoder;
use Symfony\Component\Serializer\Normalizer\ObjectNormalizer;

$encoders = [new JsonEncoder()];
$normalizers = [new ObjectNormalizer()];

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

$jsonContent = $serializer->serialize($data, 'json');

The output of the serializer will be a JSON string containing the data from the model.
