If you will write a HTML document :





 // $xml = new XMLWriter();  you know it and openURI()





<?php


 // for HTML 5


$xml->startDTD('html');


 // for XHTML 1.0


$xml->startDTD('html', '-//W3C//DTD XHTML 1.0 Strict//EN','http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd'); // standards compliant





$xml->endDTD();


?>


it will be :


<!DOCTYPE html>


or    <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN">





don't need to startDocument() .
