This service provider registers a PSR-11 compatible container as a service inside a Silex application.
PSR-11 enables developers to write code that is aware of the service container without coupling it to a specific container implementation, thus allowing to switch to another service container more easily.
Use Composer to install the package.
composer require derrabus/silex-psr11-provider
Once you have registered the service provider, you can either access the
container as service service_container or as a controller argument by using
Psr\Container\ContainerInterface as type hint.
use Psr\Container\ContainerInterface;
use Rabus\Psr11ServiceProvider\Psr11ServiceProvider;
use Silex\Application;
use Silex\Provider\ServiceControllerServiceProvider;
use Symfony\Component\HttpFoundation\RedirectResponse;
class SomeController
{
private $container;
public function __construct(ContainerInterface $container)
{
$this->container = $container;
}
public function someAction()
{
return new RedirectResponse(
$this->container->get('url_generator')->generate('home')
);
}
}
$app = new Application();
$app->register(new ServiceControllerServiceProvider());
$app->register(new Psr11ServiceProvider());
$app['some_controller'] = function ($app) {
// Inject a PSR-11 container instead of the $app
return new SomeController($app['service_container']);
};
$app->get('/', function() {
return 'Home.';
})->bind('home');
$app->get('/test1', 'some_controller:someAction');
// Type-hint the PSR-11 container instead of the $app
$app->get('/test2', function (ContainerInterface $container) {
new RedirectResponse($container->get('url_generator')->generate('home'));
});This service provider can be used as a stepping stone on the migration path from Silex to Symfony. It has been created to illustrate how to decouple Silex applications from the service container implementation.
