<?php

// Creates an instance of the DOMImplementation class
$imp = new DOMImplementation;

// Creates a DOMDocumentType instance
$dtd $imp->createDocumentType('graph''''graph.dtd');

// Creates a DOMDocument instance
$dom $imp->createDocument(""""$dtd);

// Set other properties
$dom->encoding 'UTF-8';
$dom->standalone false;

// Create an empty element
$element $dom->createElement('graph');

// Append the element
$dom->appendChild($element);

// Retrieve and print the document
echo $dom->saveXML();

?>
