[help] Anyone have suggestions for how to typehint class extensions in IDE?

[Mike Tougeron]

I'm using Zend Studio for my IDE and I was hoping someone had a suggestion for how to use variable typehinting with XenForo.

For example, I have a class that extends XenForo_Model_User:

class IGN_XenForo_Model_User extends XFCP_IGN_XenForo_Model_User {
    public function loginUserByRememberCookie($userCookie)
    {
        //blah
    }

    public function createXenforoUserFromIgnUser($ignUser)
    {
        //blah
    }

    //etc
}

When I create the user model object, I do:

/* @var $userModel IGN_XenForo_Model_User */
$userModel = XenForo_Model::create('XenForo_Model_User');

That tells my IDE to use the IGN_XenForo_Model_User class for code auto-complete. But unfortunately this doesn't include the methods from XenForo_Model_User because it extends the fictional XFCP_IGN_XenForo_Model_User class. If I switch the @var to use XenForo_Model_User it doesn't include the methods that I added in IGN_XenForo_Model_User. Kind of a catch-22

The only work-around I've been able to come up with is a local file that is part of my project (but isn't actually included or used) that has the XFCP_* classes extend the real XenForo classes to "trick" the IDE into learning the inheritance. That works but feels pretty hacky/improper so I was wondering if someone has come up with a better solution or work-around to this issue?
