I have successfuly installed Router using PHP-DI. There is some simple app example based on the article.
There are 2 files: index.php and controller.php. I want to use $container from controller. However, I have no idea how to inject it?
// index.php
use...
require_once...
$containerBuilder = new ContainerBuilder();
....
$container = $containerBuilder->build(); // I succesfuilly build a container here with all needed definitions, including Database, Classes and so on.
$routes = simpleDispatcher(function (RouteCollector $r) {
$r->get('/hello', Controller::class);
});
$middlewareQueue[] = new FastRoute($routes);
$middlewareQueue[] = new RequestHandler($container);
$requestHandler = new Relay($middlewareQueue);
$response = $requestHandler->handle(ServerRequestFactory::fromGlobals());
$emitter = new SapiEmitter();
return $emitter->emit($response);
So the code just receive Response from the dispatcher and pass it off to the emitter.
namespace ExampleApp;
use Psr\Http\Message\ResponseInterface;
class Controller
{
private $foo;
private $response;
public function __construct(
string $foo,
ResponseInterface $response
) {
$this->foo = $foo;
$this->response = $response;
}
public function __invoke(): ResponseInterface
{
$response = $this->response->withHeader('Content-Type', 'text/html');
$response->getBody()
->write("<html><head></head><body>Hello, {$this->foo} world!</body></html>");
return $response;
}
}
Now I want to add logic into Controller based on my $container: database, logger and so on. I want somehow to use $container instance which was created in index.php. I have tried a lot of ways, but nothing works proper.
