## Description

string DomDocument->dump_mem ( [bool format [, string encoding]])

Warning
This function is EXPERIMENTAL. The behaviour of this function, the name of this function, and anything else documented about this function may change without notice in a future release of PHP. Use this function at your own risk.

Creates an XML document from the dom representation. This function usually is called after building a new dom document from scratch as in the example below. The `format` specifies whether the output should be neatly formatted, or not.

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>";
    ?>

> Note: The first parameter was added in PHP 4.3.0.
