This document summarizes some key features of PHP frameworks like Silex: 1. Silex is a micro-framework for PHP that is built on the Pimple dependency injection container. It provides routing, controllers, and services out of the box. 2. Silex uses dependency injection and service providers to configure services like Twig, URL generation, sessions, and more. Services can then be accessed through the application container. 3. Testing in Silex uses the WebTestCase class to create test clients and make requests to test routes and responses. Assertions can validate crawler output and responses.

3. Новине у PHP-у
● Namespaces
● Closures
● Traits

4. Namespaces
namespace FooBar
use FooBar

5. Closures
$double = function($a) {
return $a * 2;
};

6. Traits
class Base class MyHelloWorld
{ extends Base
public function sayHello()
{ {
echo 'Hello ';
}
use SayWorld;
} }
trait SayWorld
{
$o = new
public function sayHello()
{ MyHelloWorld();
parent::sayHello();
$o->sayHello();
echo 'World!';
}
}

8. Зашто?
Фрејмворк је обично:
● тешко оружје
● тежак за учење

задатака.

10. HTTP протокол
GET /index.html HTTP/1.1
Host: www.example.com
HTTP/1.1 200 OK

11. Sinatra

12. Sinatra
require 'sinatra'
get '/hi' do
"Hello World!"
end

13. Silex

14. Silex
$app = new SilexApplication();
$app->get('/hello/{name}', function($name) {
return 'Hello '.$name;
});
$app->run();

15. Silex
$app->before(function() {
// пре обаде захтева
});
$app->after(function() {
// после обаде захтева
});
$app->finish(function() {
// после слања одговора
});

16. Silex
$app = new SilexApplication();
$app->error(function (Exception $e, $code) {
// руковање грешкама
});

17. Dependency Injection

18. Dependency Injection
class JsonUserPersister
{
private $storage;
public function __construct(StorageInterface $storage)
{
$this->storage = $storage;
}
public function persist(UserInterface $user)
{
$this->storage->store($user);
}
}

19. Pimple

20. Pimple
$container = new Pimple();
$container['cookie_name'] = 'SESSION_ID';
$container['storage_class'] = 'SessionStorage';
$container['session_storage'] = function ($c) {
return new $c['storage_class']($c['cookie_name']);
};
$container['session'] = function ($c) {
return new Session($c['session_storage']);
};

21. Silex extends Pimple
namespace Silex;
class Application extends Pimple
...

22. Silex Dependency Injection
$app = new SilexApplication();
$app['some_service'] = $app->share(function () {
return new Service();
});

23. Service Providers
$app = new SilexApplication();
$app->register(new UrlGeneratorServiceProvider());
…
$app['url_generator']->generate('home');

24. Service Providers
● Twig ● Security
● URL Generator ● Swiftmailer
● Session ● Monolog
● Validator ● Translation
● Form ● Doctrine
● HTTP Cache

25. Тестирање
class YourTest extends SilexWebTestCase
{
public function createApplication()
{
return require __DIR__.'/../../../app.php';
}
public function testFooBar()
{
// ...
}
}

26. Тестирање
public function testHomePage()
{
$client = $this->createClient();
$crawler = $client->request('GET', '/');
$this->assertTrue($client->getResponse()->isOk());
$this->assertCount(
1,
$crawler->filter('h1:contains("Contact us")')
);
$this->assertCount(1, $crawler->filter('form'));
// ...
}

27. Twig

28. Twig
$app->register(
new TwigServiceProvider(), array(
'twig.path' => __DIR__.'/views'
)
);

29. Twig
$app->get(
'/hello/{name}',
function ($name) use ($app) {
return $app['twig']->render(
'hello.twig',
array(
'name' => $name
));
}
);

30. Twig
{% extends 'layout.html.twig' %}
{% block content %}
<h1>Hello {{ name }}</h1>
{% endblock %}

32. Composer

"require": {
"silex/silex": "1.*"
}
