Simple example of how could look like injecting resources in objects

ResourceInjection.php

<?php

// Injects ZF Bootstrap resources in an object based on annotations
function InjectResources($obj) {
  $obj = $this;
  $reflObj = new \ReflectionObject($obj);
  foreach ($reflObj->getProperties() as $prop) {
    $doc = $prop->getDocComment();
    if (preg_match('/@resource(\s+(?<name>[A-Za-z_]+))?/', $doc, $m)) {
      $name = empty($m['name'])
            ? $prop->getName()
            : $m['name'];

      $bs = Zend_Controller_Front::getInstance()->getParam('bootstrap');
      if (!$bs->hasPluginResource($name)) {
        throw new \Exception('Unable to obtain resource "' . $name . '" for class ' . get_class($obj) );
      }
      $resource = $bs->getPluginResource($name);

      $prop->setAccessible(true);
      $prop->setValue($obj, $resource);
      $prop->setAccessible(false);
    }
  }
}

// Example use in a controller
class TestController extends Zend_Controller_Action
{
  /**
   * Here the resource name is taken from the variable name (log)
   * @resource 
   * @var \Zend_Log
   */
  protected $log;

  /** @resource cache */
  protected $mycache;

  public function init()
  {
    InjectResources($this);
  }

  public function indexAction()
  {
    $this->log->info('At index action');
    echo $this->mycache->load('index');
  }
}
