php-symfonyHow to persist data in PHP Symfony?

Persisting data in PHP Symfony can be done using Doctrine ORM. Doctrine is an Object Relational Mapper (ORM) which allows developers to map objects to a database.

Example code

$em = $this->getDoctrine()->getManager();
$user = new User();
$user->setName('John Doe');
$em->persist($user);
$em->flush();

This code will create a new user object and persist it to the database.

Code explanation

• $em = $this->getDoctrine()->getManager(); - This line gets the Entity Manager from the Doctrine service.
• $user = new User(); - This line creates a new User object.
• $user->setName('John Doe'); - This line sets the name of the user.
• $em->persist($user); - This line tells Doctrine to persist the user object to the database.
• $em->flush(); - This line tells Doctrine to actually execute the query and persist the data.
