PHP-DI integration with Zend Framework 2

This library provides integration for PHP-DI with Zend Framework 2.

PHP-DI is a Dependency Injection Container for PHP.

If you are looking for Zend Framework 1 integration, head over here.

Use

Require the libraries with Composer:

{
	"require": {
		"mnapoli/php-di": "*",
		"mnapoli/php-di-zf2": "*"
	}
}

To use PHP-DI in your ZF2 application, you need to make the following two changes:

In your application_root/module/Application/config/module.config.php, find the service_manager section which looks like this:

	'service_manager' => array(
		'abstract_factories' => array(
			'Zend\Cache\Service\StorageCacheAbstractServiceFactory',
			'Zend\Log\LoggerAbstractServiceFactory',
		),
		'aliases' => array(
			'translator' => 'MvcTranslator',
		),
	),

Add a factory function to the Zend Service Manager for the PHP-DI container. The result will look like this:

	'service_manager' => array(
		'abstract_factories' => array(
			'Zend\Cache\Service\StorageCacheAbstractServiceFactory',
			'Zend\Log\LoggerAbstractServiceFactory',
		),
		'aliases' => array(
			'translator' => 'MvcTranslator',
		),
		'factories' => array(
			'DI\Container' => function () {
				// Configure your container here
				return new DI\Container();
			},
		),
	),

Now in each of your controllers, you must extend DI\ZendFramework2\InjectedAbstractActionController or DI\ZendFramework2\InjectedAbstractRestfulController, depending on what type of controller it is:

 class IndexController extends AbstractActionController

becomes

use DI\ZendFramework2\InjectedAbstractActionController;

class IndexController extends InjectedAbstractActionController

or

class IndexController extends AbstractRestfulController

becomes

use DI\ZendFramework2\InjectedAbstractRestfulController;

class IndexController extends InjectedAbstractRestfulController

That's it!

Now you dependencies are injected in your controllers!
