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() .
