Who Am I?
● A PHP Developer for 10 Years
● Lots of projects no one uses,
and a few some do
● https://github.com/dragonmantank

4
Microframework
● Built off of the Symfony2
Components
● Micro Service Container
● Provides Routing
● Provides Extensions

5
Why to Not Use Silex
● You have to piece things
together
● Not great for large projects

6
Why use Silex?
● You can use the libraries you
want
● Great for small/medium
projects
● Prototypers best friend

10
Set up Silex
composer require “silex/silex”:”~1.2”

11
Sample Silex App
<?php
require_once __DIR__ . '/../vendor/autoload.php';
$app = new SilexApplication();
$app->get('/', function() use ($app) {
return 'Hello World';
});
$app->run();

13
And you add more pages
<?php
$app->get('/', function() use ($app) {/*...*/});
$app->get('/about, function() use ($app) {/*...*/});
$app->get('/contact', function() use ($app) {/*...*/});
$app->get('/services', function() use ($app) {/*...*/});
$app->run();

15
What do they do?
● Allows code reuse
● For both services and
controllers

16
Service Providers
● Twig
● URL Generator
● Session
● Validator
● Form
● HTTP Cache
● HTTP Fragments
● Security
● Remember Me
● Switftmailer
● Monolog
● Translation
● Serializer
● Doctrine
● Controllers as
Services

17
And you add templating
<?php
$app->register(new SilexProviderTwigServiceProvider(), array(
'twig.path' => __DIR__.'/../views',
));
$app->get('/', function() use ($app) {
return $app['twig']->render('homepage.html.twig');
});
$app->get('/contact', function() use ($app) {/*...*/});
$app->get('/services', function() use ($app) {/*...*/});
$app->run();

18
Adding a Form
●We need to generate the form
●We need to accept the form
●We need to e-mail the form

19
Now we add a form
<?php
use SymfonyComponentHttpFoundationRequest;
'twig.path' => __DIR__.'/views',
));
$app->register(new SilexProviderFormServiceProvider());
$app->register(new SilexProviderTranslationServiceProvider());
$app->get('/contact', function(Request $request) use ($app) {
$form = $app['form.factory']->createBuilder('form')
->add('name')
->add('email')
->getForm()
;
$form->handleRequest($request);
if($form->isValid()) {
$data = $form->getData();
// Mail it
}
return $app['twig']->render('contact.html.twig', array('form' => $form->createView()));
});
$app->get('/services', function() use ($app) {/*..});
$app->run();

22
Allow Both Methods
<?php
'twig.path' => __DIR__.'/views',
));
$app->match('/contact', function(Request $request) use ($app) {
->add('name')
->add('email')
->getForm()
;
// Mail it
}
})->method('GET|POST');
$app->run();

23
We've silently introduced a problem into our
code

24
Code Quickly Turns to
Spaghetti
http://commons.wikimedia.org/wiki/File:Spaghetti-prepared.jpg

25
Pretend to be a big framework

26
What do we need to do?
● Consistent File Layout
● Separate out functionality
● Make things more testable

27
Clean up our file structure

28
Break up that big file
● File for bootstrapping the app
● File for routes
● File for running the app

29
web/index.php
require_once __DIR__ . '/../app/bootstrap.php';
require_once __DIR__ . '/../app/routes.php';
$app->run();

30
app/bootstrap.php
$config = include_once 'config/config.php';
$app['config'] = $config;
'twig.path' => $app['config']['template_path'],
));

31
app/routes.php
$app->match('/contact', function(Request $request) use ($app) {
->add('name')
->add('email')
->getForm()
;
// Mail it
}
})->method('GET|POST');

33
For Services
● Implement
SilexServiceProviderInterface
● Implement boot() and
register()

34
For Controllers
● Implement
SilexControllerProviderInterface
● Implement connect()

35
Sample Controller
use SilexApplication;
use SilexControllerProviderInterface;
class BlogController implements ControllerProviderInterface {
public function connect(Application $app) {
$controllers = $app['controllers_factory'];
$controllers->get('/', array($this, 'index'));
$controllers->get('/inline', function() use ($app) {
/* Logic Here */
});
}
protected function index(Application $app) {
/* Logic Here */
}
}
$app->mount('/blog', new BlogController());

36
Controllers as Services
● Ships with Silex
● Allows attaching objects to
routes
● Favors dependency injection
● Framework Agnostic

37
Create our Object
// src/MyApp/Controller/IndexController.php
namespace MyAppController;
use SilexApplication;
class IndexController
{
public function indexAction(Application $app)
{
return $app['twig']->render('Index/index.html.twig');
}
public function aboutAction(Application $app) { /* … */ }
public function servicesAction(Application $app) { /* … */ }
public function contactAction(Application $app) { /* … */ }
}

38
Register Controllers as
Services
$config = include_once 'config/config.php';
$app['config'] = $config;
'twig.path' => $app['config']['template_path'],
));
$app['controller.index'] = $app->share(function() use ($app) {
return new MyAppControllerIndexController();
});

39
Register our routes
$app->get('/', 'controller.index:indexAction')->bind('homepage');
$app->get('/about', 'controller.index:aboutAction')->bind('about');
$app->get('/services', 'controller.index:servicesAction')->bind('services');
$app->match('/contact', 'controller.index:contactAction')->bind('contact')->method('GET|POST');

A Little Planning goes a Long Way
