Zend ViewHelper Sub Functions

Question

I want to add more than one function to a ViewHelper. Usually there is one function named like the class and like the file name.

How can I add several functions into one ViewHelper?

E.g. like this:

class Zend_View_Helper_MyMenuHelper extends Zend_View_Helper_Abstract
{
    public function Horizontal($parameter)
    {
         return "...";
    }
}

echo $this->MyMenuHelper()->Horizontal($parameter);

Answer 1

Alex was on the right path, but missed something in his answer: the actual myMenuHelper() method has to return the view helper itself, for this to work:

class Zend_View_Helper_MyMenuHelper extends Zend_View_Helper_Abstract
{
    public function myMenuHelper()
    {
        return $this;
    }

    public function horizontal() { ... }

    // more methods...
}

And then, as mentioned:

echo $this->myMenuHelper()->horizontal();
