How can Object Relational Mapping (ORM) be implemented in PHP programs for efficient database storage of objects?

Object Relational Mapping (ORM) can be implemented in PHP programs using libraries such as Doctrine or Eloquent to efficiently store objects in a database. These libraries map object-oriented code to relational database tables, making it easier to work with databases in a more object-oriented way. 

// Example using Eloquent ORM in Laravel

// Define a model class representing a table in the database
class User extends Model {
    protected $table = 'users';
}

// Create a new user object and save it to the database
$user = new User();
$user->name = 'John Doe';
$user->email = 'john@example.com';
$user->save();

// Retrieve a user from the database
$retrievedUser = User::find(1);

// Update a user's information
$retrievedUser->name = 'Jane Doe';
$retrievedUser->save();

// Delete a user from the database
$retrievedUser->delete();
