Today I want to share the "$template_instance" variable with a child class. How is this accomplished?

require_once("/classes/Conf.php");
require_once("/classes/Application.php");

class index extends Application
{
    private $template_instance;

    // Dependency injection
    public function __construct(Smarty $template_instance)
    {
        $this->template_instance = $template_instance;
    }

    function ShowPage()
    {
        // now let us try to move this to another class 
        // $this->template_instance->assign('name', 'Ned'); 
        // $this->template_instance->display('index.tpl'); 

    }   
}

$template_instance = new Smarty();
$index_instance = new Index($template_instance);
//$index_instance->showPage();

$printpage_instance = new printpage();
$printpage_instance->printSomething();


------------------------------------------------------------------

class printpage
{ 
 public function __construct()
 {


 }

 public function printSomething()
 {    

        // now let us try to move this to another class 
         $this->template_instance->assign('name', 'Ned'); 
         $this->template_instance->display('index.tpl'); 


 }
}
