5. require __DIR__.'/c.php'; if (!is_callable($c = @$_GET['c'] ?: function() { echo 'Woah!'; })) throw new Exception('Error'); $c();
6. Silex Symfony2 μ-framework
7. Silex is not Symfony
8. Microframework
10. What? • Bare bones • Routes mapped to controllers • The ‘C’ of ‘MVC’ • REST • Single file app (ish)
11. Why?
12. Sometimes a full-stack framework is too much for a simple task.
13. simple
14. What makes silex special?
15. • concise • extensible • testable

20. Http Kernel Interface
21. Response handle(Request $request)
22. client
23. request client
24. reponse client request
25. clean
26. PSR-0
28. Silex is not Symfony
29. Silex is a user interface for Symfony
30. require_once __DIR__.'/silex.phar'; $app = new Silex\Application(); $app->get('/', function() { return "Hello world!"; });
31. Phar require_once __DIR__.'/silex.phar'; $app = new Silex\Application(); $app->get('/', function() { return "Hello world!"; });
32. Phar require_once __DIR__.'/silex.phar'; $app = new Silex\Application(); $app->get('/', function() { return "Hello world!"; }); = FUBAR
33. Composer require_once 'vendor/autoload.php'; $app = new Silex\Application(); $app->get('/', function() { return "Hello world!"; });
34. Application require_once 'vendor/autoload.php'; $app = new Silex\Application(); $app->get('/', function() { return "Hello world!"; });
35. require_once 'vendor/autoload.php'; $app = new Silex\Application(); $app->get('/', function() { return "Hello world!"; }); Controller
36. $app->run();
38. <IfModule mod_rewrite.c> RewriteEngine On RewriteBase /some/path RewriteCond %{REQUEST_FILENAME} !-f RewriteCond %{REQUEST_FILENAME} !-d RewriteRule ^(.*)$ index.php [QSA,L] </IfModule>
39. server { index index.php location / { try_files $uri $uri/ /index.php; } location ~ index\.php$ { fastcgi_pass /var/run/php5-fpm.sock; fastcgi_index index.php; include fastcgi_params; } }
40. Wait a minute!
41. Lambdas λ
42. $(function () { $("a").on("click", function (event) { alert("Thanks for visiting!"); }); });
43. PHP 5.3
44. $f = function ($a, $b) { return $a + $b; }; $f(1, 2);
45. lazy $f = function () { exit; };
46. nested $f = function () { return function () { return true; }; }; $g = $f(); $value = $g();
47. scope $outer = 'world'; $f = function () use ($outer) { $inner = 'hello'; return "$inner $outer"; }; => "hello world"
48. scope $helloWorld = function () { $outer = 'world'; $f = function () use ($outer) { $inner = 'hello'; return "$inner $outer"; }; return $f(); }
49. passing $output = function ($info) { echo $info."\n"; }; $doStuff = function ($output) { $output('doing some magic'); doMagic(); $output('did some magic'); };
50. factory $userFactory = function ($name) { return new User($name); }; // ... $user = $userFactory($_POST['name']);
51. event listener $emitter = new EventEmitter(); $emitter->on('user.create', function (User $user) { $msg = sprintf("User %s created.", $user->name); log($msg); });
52. Usage
53. $app->get('/', function () { return "Hello world!"; });
54. Dynamic Routing
55. $app->get('/hello/{name}', function ($name) use ($app) { return "Hello ".$app->escape($name); });
56. $app->get('/hello/{name}', function ($name) use ($app) { return "Hello ".$app->escape($name); });
57. Controllers
58. assert $app->get('/blog/{id}', function ($id) { ... }) ->assert('id', '\d+');
59. value $app->get('/{page}', function ($page) { ... }) ->value('page', 'index');
60. bind $app->get('/', function () { ... }) ->bind('homepage'); $app['url_generator']->generate('homepage')
61. bind $app->get('/blog/{id}', function ($id) { ... }) ->bind('blog.post'); $app['url_generator'] ->generate('blog.post', array('id' => $id))
62. convert $app->get('/blog/{post}', function (Post $post) { ... }) ->convert('post', function ($post) use ($app) { $id = (int) $post; return $app['posts']->find($id); });
63. Before & After
64. $app->before(function () { ... }); $app->get('/', function () { ... }); $app->after(function () { ... });
65. $app->before(function (Request $request) { $loggedIn = $request ->getSession() ->get('logged_in'); if (!$loggedIn) { return new RedirectResponse('/login'); } });
66. $app->after(function (Request $request, Response $response) { // tweak the Response });
67. Methods
68. • get • post • put • delete • head • options
69. $app->get('/posts/{id}', ...); $app->post('/posts', ...); $app->put('/posts/{id}', ...); $app->delete('/post/{id}', ...);
70. use Symfony\Component\HttpFoundation\Request; use Symfony\Component\HttpFoundation\Response; $app->post('/message', function (Request $request) { mail( 'me@me.me', 'New message', $request->get('body') ); return new Response('Email has been sent!', 201); });
71. Caching
72. Error Handling
73. use Symfony\Component\HttpFoundation\Response; $app->error(function (\Exception $e, $code) { return new Response('Whoops!', $code); });
74. $app->abort(404, "Could not find the thing.");
75. $app['debug'] = true;
76. Redirecting
77. $app->get('/', function () use ($app) { return $app->redirect('/hello'); });
78. Pimple
79. ~50 NCLOC
80. $container = new Pimple();
81. $app = new Silex\Application();
82. Parameters $app['some_parameter'] = 'value'; $app['asset.host'] = 'http://cdn.mysite.com/'; $app['database.dsn'] = 'mysql:dbname=myapp';
83. Services $app['some_service'] = function () { return new Service(); };
84. $service = $app['some_service'];
85. Dependencies $app['some_service'] = function ($app) { return new Service( $app['some_other_service'], $app['some_service.config'] ); };
86. Shared $app['some_service'] = $app->share(function () { return new Service(); });
87. Protected $app['lambda_parameter'] = $app->protect( function ($a, $b) { return $a + $b; }); // will not execute the lambda $add = $app['lambda_parameter']; // calling it now echo $add(2, 3);
88. Exposed Services • debug • request • autoloader • routes • controllers • dispatcher • resolver • kernel
89. Service Providers
90. interface ServiceProviderInterface { function register(Application $app); }
91. Core Service Providers • doctrine • form • http cache • monolog • session • swiftmailer • symfony bridges • translation • twig • url generator • validator

93. Redis
94. $app->register(new PredisServiceProvider());
95. $app->get('/{id}', function ($id) use ($app) { $key = 'pastes:'.$id; $paste = $app['predis']->hgetall($key); ... });
97. • smallish sites • well-defined scope • prototyping • restful apis When to use
98. and many more...
100. New feature: Streaming
101. $app->get('/some-video', function () use ($app) { $file = $app['app.video_filename']; $stream = function () use ($file) { readfile($file); }; return $app->stream( $stream, 200, array('Content-Type' => 'video/mpeg') ); });
102. New feature: Middlewares
103. $mustBeLogged = function (Request $request) use ($app) { if (!$app['session']->has('userId')) { return $app->redirect('/user/login'); } }; $app->get('/user/my-profile', function () { ... }) ->middleware($mustBeLogged);
104. New feature: JSON helper
105. $app->get('/users/{id}', function ($id) use ($app) { $user = getUser($id); if (!$user) { $message = 'The user was not found.'; $error = array('message' => $message); return $app->json($error, 404); } return $app->json($user); });
106. New feature: Finish filter
107. $app->finish(function () { // send e-mails // very slow query // some slow API calls });
