Accessing variables with Zend_Rest_Route

I'm new to PHP and Zend so hopefully this is an easy one...

Simply put - how do I access an id or variable with Zend_Rest_Route?

In my开发者_Go百科 bootstrap I have

$frontController = Zend_Controller_Front::getInstance();
$router = $frontController-getRouter();
$restRoute = new Zend_Rest_Route($frontController);
$router->(addRoute('api', $restRoute));

Typically when I set standard routes, I get the id by putting in my controller...

$router->addRoute(
          'item',
          new Zend_Controller_Route_Route(
             '/item/:itemID',
                array('controller' => 'index', 'action' => 'manipulateItem')
                ));

So I need to be able to access the 'id##' from localhost/api/id##

The ID parameter in REST routes is accessible as a controller parameter named id. In your controller actions e.g. like this:

$id = $this->_getParam('id');
