I found this script online that uses php to change an html file into an MS Document. But for some reason, it isn't working for me. Does anybody know why it wouldn't?

Here is the source code:
Example.php
PHP Code:
<?php
    
include("doc.inc.php");
    
    
$htmltodoc= new HTML_TO_DOC();
    
    
//$htmltodoc->createDoc("reference1.html","test");
    
$htmltodoc->createDocFromURL("http://www.google.com","test");
    

?>
doc.inc.php
PHP Code:
<?php
