Automatically inject resources into controller

I'm trying to implement dependency injection in our Zend Framework project.

In previous APS.NET based projects we've used StructureMap and overwritten the DefaultControllerFactory to inject the dependencies into the controllers.

I'm not sure where to do the injection in Zend Framework? I've looked into Zend_Controller_Plugin_Abstract and Zend_Controller_Action_Helper_Abstract but none of them seems to enable me to inject into the currently instantiated controller.

I would love to be able to inject into the constructor of the current controller like i do in ASP.NET, but setters are acceptable (I guess).

Any ideas as to how to accomplish this or something similar?

Ultimately i would like to be able to do something like this:

MyController extends Zend_Controller_Action {
  // private vars
  [...]

  public function __constructor($authenticationService, $userRepository) {
    $this->_authServ = $authenticationService;
    $this->_userRepo = $userRepository;
  }    

}

I would like to do something like i do for stuctureMap:

For(authenticationService).Use(WhatEverClass);

or maybe:

$currentController->authServ = $authenticationService;
$currentController->userRepo = $userRepository;

In short: Where can we intercept the creation of (or get the instance of) the current controller?

Thanks! /Jon

Check out also PHP-DI, this is a dependency injection library that integrates with Zend Framework. It works with annotations.

It enables you to do things like:

MyController extends Zend_Controller_Action {
    /**
     * @Inject
     * @var MyService
     */
    private $myService;

    public function helloAction() {
        return $this->myService->sayHello();
    }
}

Zend Framework lead developer Matthew Weier O'Phinney has a post that seems to address the idea of injecting resources into controllers:
