DomDocument->dump_mem — Dumps the internal XML tree back into a string

### Description

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

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.
