Is it feasible to abstract queries in a way that they can seamlessly transition from MySQL to MongoDB without major adjustments, as suggested in the thread?

To abstract queries in a way that they can seamlessly transition from MySQL to MongoDB without major adjustments, you can use an ORM (Object-Relational Mapping) library like Doctrine. By defining your database schema using Doctrine annotations or configuration files, you can write queries in a database-agnostic way. This allows you to switch between different database systems with minimal code changes. 

// Example using Doctrine ORM

// Define your entity class with annotations
/**
 * @Entity
 * @Table(name="users")
 */
class User
{
    /**
     * @Id
     * @Column(type="integer")
     * @GeneratedValue
     */
    private $id;

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

    // Other properties and methods
}

// Create EntityManager with database connection settings
$entityManager = EntityManager::create($conn, $config);

// Use EntityManager to perform database operations
$user = new User();
$user->setName('John Doe');

$entityManager->persist($user);
$entityManager->flush();

// Query for users
$users = $entityManager->getRepository(User::class)->findAll();
