1. PHP под микроскопом
Саша Стаменковић (@umpirsky)

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

9. Превише за обављање једноставних
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.*"
}
}

33. Composer
