PHP-DI integration with Zend Framework 1

This library provides integration for PHP-DI with Zend Framework 1.

This project also contains the Zend Framework quickstart configured with PHP-DI.

PHP-DI is a Dependency Injection Container for PHP.

Set up

Require the libraries with Composer:

{
    "require": {
        "mnapoli/php-di": "*",
        "mnapoli/php-di-zf1": "*"
    }
}

To use PHP-DI in your ZF1 application, you need to change the Dispatcher used by the Front Controller in the Bootstrap.

    /**
     * Initialize the dependency injection container
     */
    protected function _initDependencyInjection()
	{
		$container = new \DI\Container();

        $dispatcher = new \DI\ZendFramework1\Dispatcher();
        $dispatcher->setContainer($container);

        $frontController = Zend_Controller_Front::getInstance();
        $frontController->setDispatcher($dispatcher);
	}

That's it!

Usage

Now you can inject dependencies in your controllers!

For example, here is the GuestbookController of the quickstart:

use DI\Annotation\Inject;

class GuestbookController extends Zend_Controller_Action
{
    /**
     * This dependency will be injected by PHP-DI
     * @Inject
     * @var Application_Service_GuestbookService
     */
    private $guestbookService;

    public function indexAction()
    {
        $this->view->entries = $this->guestbookService->getAllEntries();
    }

    public function signAction()
    {
        $request = $this->getRequest();
        $form    = new Application_Form_Guestbook();

        if ($this->getRequest()->isPost() && $form->isValid($request->getPost())) {
            $this->guestbookService->addEntry($form->getValues());
            return $this->_helper->redirector('index');
        }

        $this->view->form = $form;
    }

}

Zend Framework quickstart

The quickstart is in the quickstart/ folder. You can look at it to see how PHP-DI can be integrated to a ZF1 application.

To run the quickstart, get composer and install the dependencies:

$ curl -s http://getcomposer.org/installer | php
$ php composer.phar install

Note: I tried not to diverge too much from the official quickstart. So the code may look messy, but that's how the ZF quickstart is ;)
