Doctrine ORM EntityManager is an object-relational mapping (ORM) tool that is built on top of the PHP Data Objects (PDO) library. It provides a way for PHP developers to interact with databases in an object-oriented manner. The EntityManager is the central class in Doctrine ORM, responsible for managing entities and their relationships with the database.
Example 1:
$app->get('/users/{id}', function ($request, $response, $args) { $entityManager = $this->get('EntityManager'); $user = $entityManager->find('User', $args['id']); if (!$user) { throw new \Exception("User not found for id ".$args['id']); } return $response->withJson($user); });
In this example, we're using the EntityManager to find a user based on a given ID. The EntityManager is injected into the function via the service container, and then used to query the database for the requested user.
In this example, we're creating a new User entity and saving it to the database using the EntityManager. The persist() method is used to add the new entity to the EntityManager, and the flush() method is used to commit the changes to the database.
The Doctrine ORM package library is a popular PHP library for working with databases, particularly with object-relational mapping. It provides a wide range of features for managing databases and defining models in an object-oriented manner.
