(no version information, might be only in CVS)

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.
