I use something like this:

index.php
<?php
include 'view.php';
$view=new View;
$view->render('index.tpl');


view.php
<?php
class View{
    private function myFunc(){
        //doSmth;
    }
    public function render($file){
        include 'templates'.$file;
    }
}

templates/index.tpl
<?php /* @var $this Viewer */?> //MakenetBeans known that I use $this as instanse of Viewer class
//some html
<?php $this->[Code Completion]?>
//some other html


I want see here private methods because I use $this 
$this can't be used as usual variable so if I use it, I can use private methods too.
