4. Silex Symfony goes micro μ

5. Silex is not Symfony

6. Microframework

7. None

8. What? • Bare bones • Routes mapped to controllers •

   The ‘C’ of ‘MVC’ • REST • Single file app

9. Why?

10. Sometimes a full-stack framework is too much for a simple

    task.

11. simple

12. What makes silex special?

13. • concise • extensible • testable

18. Http Kernel Interface

19. Response handle(Request $request)

20. client

21. request client

22. reponse client request

23. clean

24. PSR-0

25. None

26. Silex is not Symfony

27. Silex is a user interface for Symfony

28. require_once __DIR__.'/silex.phar'; $app = new Silex\Application(); $app->get('/', function() { return

    "Hello world!"; });

29. Phar require_once __DIR__.'/silex.phar'; $app = new Silex\Application(); $app->get('/', function() {

    return "Hello world!"; });

30. Application require_once __DIR__.'/silex.phar'; $app = new Silex\Application(); $app->get('/', function() {

    return "Hello world!"; });

31. require_once __DIR__.'/silex.phar'; $app = new Silex\Application(); $app->get('/', function() { return

    "Hello world!"; }); Controller

32. $app->run();

33. None

34. <IfModule mod_rewrite.c> RewriteEngine On RewriteBase /some/path RewriteCond %{REQUEST_FILENAME} !-f RewriteCond

    %{REQUEST_FILENAME} !-d RewriteRule ^(.*)$ index.php [QSA,L] </IfModule>

35. server { location / { if (-f $request_filename) { break;

    } rewrite ^(.*) /index.php last; } location ~ index\.php$ { fastcgi_pass /var/run/php5-fpm.sock; fastcgi_index index.php; include fastcgi_params; } }

36. Wait a minute!

37. Lambdas λ

38. $(function () { $("a").click(function (event) { alert("Thanks for visiting!"); });

    });

39. PHP 5.3

40. $f = function ($a, $b) { return $a + $b;

    }; $f(1, 2);

41. lazy $f = function () { exit; };

42. nested $f = function () { return function () {

    return true; }; }; $g = $f(); $value = $g();

43. scope $outer = 'world'; $f = function () use ($outer)

    { $inner = 'hello'; return "$inner $outer"; }; => "hello world"

44. scope $helloWorld = function () { $outer = 'world'; $f

    = function () use ($outer) { $inner = 'hello'; return "$inner $outer"; }; return $f(); }

45. passing $output = function ($info) { echo $info."\n"; }; $doStuff

    = function ($output) { $output('doing some magic'); doMagic(); $output('did some magic'); };

46. factory $userFactory = function ($name) { return new User($name); };

    // ... $user = $userFactory($_POST['name']);

47. Usage

48. $app->get('/', function () { return "Hello world!"; });

49. Dynamic Routing

50. $app->get('/hello/{name}', function ($name) use ($app) { return "Hello ".$app->escape($name); });

51. $app->get('/hello/{name}', function ($name) use ($app) { return "Hello ".$app->escape($name); });

52. Controllers

53. assert $app->get('/blog/{id}', function ($id) { ... }) ->assert('id', '\d+');

54. value $app->get('/{page}', function ($page) { ... }) ->value('page', 'index');

55. bind $app->get('/', function () { ... }) ->bind('homepage'); $app['url_generator']->generate('homepage')

56. bind $app->get('/blog/{id}', function ($id) { ... }) ->bind('blog_post'); $app['url_generator'] ->generate('blog_post',

    array('id' => $id))

57. convert $app->get('/blog/{post}', function (Post $post) { ... }) ->convert('post', function

    ($post) use ($app) { $id = (int) $post; return $app['posts']->find($id); });

58. Before & After

59. $app->before(function () { ... }); $app->get('/', function () { ...

    }); $app->after(function () { ... });

60. $app->before(function (Request $request) { $loggedIn = $request ->getSession() ->get('logged_in'); if

    (!$loggedIn) { return new RedirectResponse('/login'); } });

61. $app->after(function (Request $request, Response $response) { // tweak the Response

    });

62. $app->after(function ( Request $request, Response $response, ) use ($app) {

    $response->headers->set('x-csrf-token', $app['csrf_token']); });

63. REST

64. • get • post • put • delete • head

    • options • patch

65. $app->get('/posts/{id}', ...); $app->post('/posts', ...); $app->put('/posts/{id}', ...); $app->delete('/post/{id}', ...);

66. use Symfony\Component\HttpFoundation\Request; use Symfony\Component\HttpFoundation\Response; $app->post('/message', function (Request $request) { mail(

    '[email protected]', 'New message', $request->get('body') ); return new Response('Email has been sent!', 201); });

67. Caching

68. Error Handling

69. use Symfony\Component\HttpFoundation\Response; $app->error(function (\Exception $e, $code) { return new Response('Whoops!',

    $code); });

70. use Symfony\Component\HttpKernel\Exception\NotFoundHttpException; throw new NotFoundHttpException("Could not find what you were

    looking for.");

71. $app->abort(404, "Could not find the thing.");

72. $app['debug'] = true;

73. Redirecting

74. $app->get('/', function () use ($app) { return $app->redirect('/hello'); });
