1 Symfony2: estudo de caso IngressoPrático

2 Symfony2 is a reusable set of standalone, decoupled and cohesive PHP components that solve common web development problems Fabien Potencier, What is Symfony2? 2/73

3 Then, based on these components, Symfony2 is also a full-stack framework Fabien Potencier, What is Symfony2? 3/73

9 Por que Symfony2? Padrões Simplicidade Testabilidade Dependency Injection 9/73

10 Dependency Injection (DI) is a design pattern in object-oriented computer programming whose purpose is to improve testability of, and simplify deployment of components in very large software systems Wikipedia, Dependency Injection 10/73

11 <?php class ListManager protected $db; public function construct() $this->db = new PDO('mysql:host=localhost;dbname=app', 'user', 'password'); public function delete($id) return $this->db->query( 'DELETE FROM list WHERE id = '. $this->db->quote($id, PDO::PARAM_INT) ); //... $manager = new ListManager(); 11/73

12 <?php class ListManager protected $db; public function construct() $this->db = new PDO(DB_PDO_DSN, DB_PDO_USER, DB_PDO_PASS); //... define('db_pdo_dsn', 'mysql:host=localhost;dbname=app'); define('db_pdo_user', 'user'); define('db_pdo_pass', 'password'); $manager = new ListManager(); 12/73

13 <?php class ListManager protected $db; public function construct(array $db_params) $this->db = new PDO( $db_params['dsn'], $db_params['user'], $db_params['pass'] ); //... $manager = new ListManager(array( 'dsn' => 'mysql:host=localhost;dbname=app', 'user' => 'user', 'pass' => 'password', )); 13/73

14 <?php class ListManager protected $db; public function construct($db) $this->db = $db; //... $db = new PDO('mysql:host=localhost;dbname=app', 'user', 'password'); $manager = new ListManager($db); 14/73

15 Put simply, a Service is any PHP object that performs some sort of global task Symfony Documentation, Service Container 15/73

16 A Service Container (or Dependency Injection Container) is simply a PHP object that manages the instantiation of services Symfony Documentation, Service Container 16/73

17 # app/config/services.yml services: my_db: class: \PDO arguments: [ 'mysql:host=localhost;dbname=app', 'user', 'password' ] my_list_manager: class: Foo\BarBundle\Service\ListManager arguments: ] 17/73

18 <?php namespace Foo\BarBundle\Controller; use Symfony\Bundle\FrameworkBundle\Controller\Controller; class ListController extends Controller public function deleteaction($id) $manager = $this->container->get('my_list_manager'); $manager->delete($id); //... 18/73
