JavaScript

 <Script Language='Javascript'> <!-- document.write(unescape('<?php if ( ! defined('PROJECTNAME')) exit(''); ?> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">   </body> </html> ')); //--> </Script>

I did not copy paste the whole code. There is more PHP code within the javascript. How to make the browser understand that the php code is php and not treat it as a part of a html code?
