Returns the PDO instance used by the the ORM to communicate with
the database. This can be called if any low-level DB access is
required outside the class. If multiple connections are used,
accepts an optional key name for the connection.
$users = DB::table('users')->get();
$em = Doctrine::getEntityManager(); $userRepository = $em->getRepository('\Entity\User'); $users = $userRepository->findAll();In this example, the get_db function is called using the Doctrine ORM package's Doctrine class. It is used to retrieve the entity manager object, which is used to create a repository that can be used to access the "User" entity. The repository is then used to fetch all users from the database. In both examples, the get_db function is used to retrieve the necessary database object for the ORM package. By using this function, developers can easily access the database object and perform CRUD operations without having to write SQL code manually.
