Symfony 2
This document summarizes Symfony 2, an evolution of Symfony 1.x that uses components like Doctrine, PHPUnit and SwiftMailer. It has the same philosophy of being full-stack, configurable and testable, but with a new foundation utilizing PHP 5.3 features. Key areas discussed include Symfony components, dependency injection, event dispatching, and using the Symfony sandbox for experimentation.

- 2. An evolution ofsymfony 1.x • Same philosophy: • Full stack • Configurable • Testable • Components • Brand new foundation
- 3. Don’t reinvent thewheel • Doctrine • PHPUnit • SwiftMailer • Zend_Cache • Zend_Log
- 4. PHP 5.3 • Namespaces • Anonymous functions / closures • Late static binding
- 7. Symfony Components • Standalone libraries • Each with a specific scope • components.symfony-project.org
- 8. Symfony Components • BrowserKit • Process • Console • RequestHandler • CssSelector • Routing • DependencyInjection • Templating • DomCrawler • Yaml • EventDispatcher • OutputEscaper
- 9. Dependency Injection • A method of supplying an external dependency
- 10. Dependency Injection class User { protected $session; public function __construct(Session $session) { $this->session = $session; } }
- 11. DI Container • A method of organizing dependencies • Adds a configuration layer • Dependency injection does not require a container!

- 15. Event Dispatcher • Implements the observer design pattern • Similar to events in JavaScript
- 16. Event Dispatcher use SymfonyComponentsEventDispatcherEvent; classArticle { protected $dispatcher; public function __construct($dispatcher) { $this->dispatcher = $dispatcher; } public function save() { // ... $event = new Event($this, ‘article.save’); $this->dispatcher->notify($event); } }
