How can an ORM like Doctrine simplify database operations and improve code readability in PHP applications?

Using an ORM like Doctrine can simplify database operations by abstracting away the need to write raw SQL queries and allowing developers to work with PHP objects instead. This can improve code readability by making database interactions more intuitive and reducing the amount of boilerplate code needed for CRUD operations. 

// Example code using Doctrine ORM to simplify database operations and improve code readability

// Define an entity class representing a table in the database
/**
 * @Entity
 * @Table(name="users")
 */
class User
{
    /**
     * @Id
     * @Column(type="integer")
     * @GeneratedValue
     */
    protected $id;

    /**
     * @Column(type="string")
     */
    protected $name;

    // Getters and setters
}

// Create a new user object
$user = new User();
$user->setName('John Doe');

// Save the user object to the database
$entityManager->persist($user);
$entityManager->flush();

// Retrieve a user object by its ID
$user = $entityManager->find(User::class, 1);

// Update a user object
$user->setName('Jane Doe');
$entityManager->flush();

// Delete a user object
$entityManager->remove($user);
$entityManager->flush();
