title: Zend Framework: Need advice on how to implement a controller helper
body: <p>i need advice on how i can implement this action helper. currently, i have something like </p>
  
  <pre><code>class Application_Controller_Action_Helper_AppendParamsToUrl extends Zend_Controller_Action_Helper_Abstract {
      function appendParamsToUrl($params = array()) {
          $router = Zend_Controller_Front::getInstance()-&gt;getRouter();
          $url = $router-&gt;assemble($params);
  
          if (!empty($_SERVER['QUERY_STRING'])) {
              $url .= $_SERVER['QUERY_STRING'];
          }
          return $url;
      }
  }
  </code></pre>
  
  <p>but as you can see, i think the function should be a static function? but how will that find into this <code>Zend_Controller_Action_Helper</code> thingy?</p>
