Access view from inside a view helper

Ready to have your mind blown? I wanted to access a view helper from inside another view helper and it doesn't allow it by default. It turns out you have to add the function setView() to your view helper and then you will have access to the view helper. The trick (in PHP 5.3 at least) is to make sure you include the Zend_View_Interface before you name the parameter or it won't work (you'll get a nasty error message).

class Zend_View_Helper_DisplaySomeData extends Zend_View_Helper_Abstract{ 
     protected $_view; 
     public function setView(Zend_View_Interface $view){
        $this->_view = $view; 
     } 

     public function DisplaySomeData($data){ 
        return $this->_view->SomeOtherViewHelper($data) . ' some text'; 
     } 
}
