How can ORM libraries like Doctrine help simplify database operations in PHP projects?

ORM libraries like Doctrine help simplify database operations in PHP projects by abstracting the interaction with the database, allowing developers to work with objects rather than raw SQL queries. This makes it easier to manage relationships between entities, perform CRUD operations, and ensure data integrity. Additionally, ORM libraries handle tasks such as query optimization, caching, and security, reducing the need for manual intervention and improving overall code quality. 

<?php

// Include the Composer autoloader to load Doctrine
require_once 'vendor/autoload.php';

// Create a Doctrine EntityManager instance
use Doctrine\ORM\Tools\Setup;
use Doctrine\ORM\EntityManager;

$paths = [__DIR__ . '/Entities'];
$isDevMode = true;

$dbParams = [
    'driver'   => 'pdo_mysql',
    'user'     => 'root',
    'password' => 'root',
    'dbname'   => 'my_database',
];

$config = Setup::createAnnotationMetadataConfiguration($paths, $isDevMode);
$entityManager = EntityManager::create($dbParams, $config);

// Now you can use $entityManager to interact with your database using Doctrine ORM
