### Description

Example#1 Creating a simple HTML document header

`<?php
$doc = domxml_new_doc("1.0");
$root = $doc->create_element("HTML");
$root = $doc->append_child($root);
$head = $doc->create_element("HEAD");
$head = $root->append_child($head);
$title = $doc->create_element("TITLE");
$title = $head->append_child($title);
$text = $doc->create_text_node("This is the title");
$text = $title->append_child($text);
echo "<PRE>";
echo htmlentities($doc->dump_mem(true));
echo "</PRE>";
?>`
