Matthew Weier O'Phinney has posted an answer to a request a fellow PHP community member had about using bootstrap resources in actions in your Zend Framework application. This post shows how it can be done in a proof of concept.
Basically, he'd like to see any resource initialized by the bootstrap immediately available as simply a public member of his action controller. So, for instance, if you were using the "DB" resource in your application, your controller could access it via $this->db. I quickly drafted up a proof of concept for him using an action helper.
The resource injection helper extends the Zend_Controller_Action_Helper_Abstract and allows you to name the resources you'd like pushed into the controller as a part of the bootstrap process. There's an issue with the approach, though - lack of controller over what's actually injected so he modified it to push the dependency list in from the controller rather than limiting it to the bootstrap.
