How to use dependency injection in Zend Framework?

Question

Currently I am trying to learn the Zend Framework and therefore I bought the book \"Zend Framework in Action\".

In chapter 3, a basic model and controller is introduced

Answer 1

With the Service Manager at Zend Framework 3.

Official Documentation:

https://zendframework.github.io/zend-servicemanager/

1. Dependencies at your Controller are usually be injected by DI Constructor injector.
2. I could provide one example, that inject a Factory responsible to create the ViewModel instance into the controller.

Example:

Controller `

class JsonController extends AbstractActionController
{
    private $_jsonFactory;
    private $_smsRepository;
    public function __construct(JsonFactory $jsonFactory, SmsRepository $smsRepository)
    {
        $this->_jsonFactory = $jsonFactory;
        $this->_smsRepository = $smsRepository;
    }
...
}

Creates the Controller

class JsonControllerFactory implements FactoryInterface
{
    /**
     * @param ContainerInterface $serviceManager
     * @param string $requestedName
     * @param array|null $options
     * @return JsonController
     */
    public function __invoke(ContainerInterface $serviceManager, $requestedName, array $options = null)
    {
        //improve using get method and callable
        $jsonModelFactory = new JsonFactory();
        $smsRepositoryClass = $serviceManager->get(SmsRepository::class);
        return new JsonController($jsonModelFactory, $smsRepositoryClass);
    }
}
