21. foo.bar foo.getBar() foo['bar']
22. $language = new ExpressionLanguage(); echo $language->evaluate('1 + 1'); // will echo 2 echo $language->compile('1 + 2'); // will echo "(1 + 2)"
23. not foo or bar foo in ['foo', 'bar'] foo ? true : false foo matches "/^foo/i"

43. The Request Stack https://secure.flickr.com/photos/kemped/3705729840
44. What is a scope? What is a strict service? What is a synchronized service?
45. Master Request {{ render(controller('a:b:c')) }} Sub-Request
46. Request Response response Call Controller response? expection Sub-Request terminate controller view resolve controller resolve arguments request exception “sub-response” content
47. Call Controller Request Response response response? expection Sub-Request terminate controller view resolve controller resolve arguments request exception “sub-response” content
48. class FooService { public function __construct(Request $request) { $this->request = $request; } public function doSomething() { $this->request->...(); } }
49. class FooService { public function __construct(ContainerInterface $container) { $this->container = $container; } public function doSomething() { $this->container->get('request')->...(); } }
50. Inject the dependencies Not the Container Pro Tip #1
51. Scopes Strict services Synchronized services
53. How can I depend on the Request in my services?
54. use Symfony\Component\HttpFoundation\RequestStack; class FooService { public function __construct(RequestStack $requestStack) { $this->requestStack = $requestStack; } public function doSomething() { $this->requestStack->getCurrentRequest()->...(); } }
55. $requestStack->getCurrentRequest()
56. class FooController { public function indexAction(Request $request) { $request->...(); } } class FooListener { public function onKernelRequest(GetResponseEvent $event) { $event->getRequest()->...(); } }
57. Inject the Request Stack Not the Request Pro Tip #2
