&reftitle.description; `string` `DomDocument::dump_mem` `bool` `format` `string` `encoding`

### 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>";
    ?>

The first parameter was added in PHP 4.3.0.
