简单的手工PHP模板引擎无法正常工作! 请帮忙

These are the class definitions

<?php
  abstract class MyTemplate {

  protected $arrayOfSpaces;
  protected $arrayOfVariables;
  protected $output;

  protected abstract function __construct(); 

  function outputHTML(){
    echo $output; //Apparently, the problem is HERE. <<<<>>>>>
  }
}
  class MyTemplateMain extends MyTemplate {
   function __construct(){
     $this->output="<!DOCTYPE html PUBLIC \"-//W3C//DTD XHTML 1.0 Transitional//EN\"
             \"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd\">
             <html>
             <head>
             </head>
             <body>
             I love Rock n Roll!!!
             </body>
             </html>";
    }

  }
?>

And this is where I launch this page

<?php 
  require_once("view/templates.php");

  $page=new MyTemplateMain();
  $page->outputHTML();



?>

Doesn't work, though. Just shows a blank page, without the String I love rock n roll which was supposed to appear in the body.

I'm sure there are better ways to implement templates but I just want to figure out why this particular example doesn't work

Any help is appreciated. Thanks

PS: The quotes are all duly escaped and the file paths are ok too
