What? • Bare bones • Routes mapped to controllers •
The ‘C’ of ‘MVC’ • REST • Single file app
Why?
Sometimes a full-stack framework is too much for a simple
task.

Lambdas λ
$(function () { $("a").click(function (event) { alert("Thanks for visiting!"); });
});
PHP 5.3
$f = function ($a, $b) { return $a + $b;
}; $f(1, 2);
lazy $f = function () { exit; };
nested $f = function () { return function () {
return true; }; }; $g = $f(); $value = $g();
scope $outer = 'world'; $f = function () use ($outer)
{ $inner = 'hello'; return "$inner $outer"; }; => "hello world"
scope $helloWorld = function () { $outer = 'world'; $f
= function () use ($outer) { $inner = 'hello'; return "$inner $outer"; }; return $f(); }
passing $output = function ($info) { echo $info."\n"; }; $doStuff
= function ($output) { $output('doing some magic'); doMagic(); $output('did some magic'); };
factory $userFactory = function ($name) { return new User($name); };
// ... $user = $userFactory($_POST['name']);
Usage
$app->get('/', function () { return "Hello world!"; });
Dynamic Routing
$app->get('/hello/{name}', function ($name) use ($app) { return "Hello ".$app->escape($name); });
$app->get('/hello/{name}', function ($name) use ($app) { return "Hello ".$app->escape($name); });
Controllers
assert $app->get('/blog/{id}', function ($id) { ... }) ->assert('id', '\d+');
value $app->get('/{page}', function ($page) { ... }) ->value('page', 'index');
bind $app->get('/', function () { ... }) ->bind('homepage'); $app['url_generator']->generate('homepage')
bind $app->get('/blog/{id}', function ($id) { ... }) ->bind('blog_post'); $app['url_generator'] ->generate('blog_post',
array('id' => $id))
convert $app->get('/blog/{post}', function (Post $post) { ... }) ->convert('post', function
($post) use ($app) { $id = (int) $post; return $app['posts']->find($id); });
Before & After
$app->before(function () { ... }); $app->get('/', function () { ...
}); $app->after(function () { ... });
$app->before(function (Request $request) { $loggedIn = $request ->getSession() ->get('logged_in'); if
(!$loggedIn) { return new RedirectResponse('/login'); } });
$app->after(function (Request $request, Response $response) { // tweak the Response
});
$app->after(function ( Request $request, Response $response, ) use ($app) {
$response->headers->set('x-csrf-token', $app['csrf_token']); });
REST
• get • post • put • delete • head
• options • patch
$app->get('/posts/{id}', ...); $app->post('/posts', ...); $app->put('/posts/{id}', ...); $app->delete('/post/{id}', ...);
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); });
Caching
Error Handling
use Symfony\Component\HttpFoundation\Response; $app->error(function (\Exception $e, $code) { return new Response('Whoops!',
$code); });
use Symfony\Component\HttpKernel\Exception\NotFoundHttpException; throw new NotFoundHttpException("Could not find what you were
looking for.");
$app->abort(404, "Could not find the thing.");
$app['debug'] = true;
Redirecting
$app->get('/', function () use ($app) { return $app->redirect('/hello'); });
