// a first service
class MyFirstService implements ServiceInterface 
{
	public function hello(string $name):void

		echo sprintf("Hello %s!", $name);

		$this->myFirstClass = $myFirstClass;
	}
	
	public function helloWorld():void
	{
		$this->myFirstClass->hello("World");
	}

// calling the second service, the service manager is going to first instantiated MyFirstService
// then instantiate MySecondService with MyFirstService as a parameter.
$serviceManager = new ServicesManager();
$mySecondService = $serviceManager->getService(MySecondService::class);
$mySecondService->helloWorld();

// you also can add external objects to makes them available to the servides,
// for instance a PSR-7 ServerRequest object or Doctrine's EntityManager.
$serviceManager->addService($entityManager);

// the service manager will pass the instance of the service manager added
// using addService()
class MyThirdService {
    public function __construct(EntityManager $entityManager) { }
