Seen a couple of bug reports and gotchas with this one but not a simple code example. Just in case someone finds it useful:
<?php
// serve xml doc as xml
header('Content-type: application/xml');
// set up the document
$xml = new XmlWriter();
$xml->openMemory();
$xml->startDocument('1.0', 'UTF-8');
$xml->startElement('mydoc');
$xml->startElement('myele');
// CData output
$xml->startElement('mycdataelement');
$xml->writeCData("text for inclusion within CData tags");
$xml->endElement();
// end the document and output
$xml->endElement();
$xml->endElement();
echo $xml->outputMemory(true);
?>
Outputs:
<?xml version="1.0" encoding="UTF-8"?>
<mydoc>
<myele>
<mycdataelement><![CDATA[text for inclusion within CData tags]]>
</mycdataelement>
</myele>
</mydoc>

$xml->startDocument('1.0', 'UTF-8');
$xml->startElement('mydoc');
$xml->startElement('myele');

i don't know if this is a bug with the underlying c code or not, or this is by design (i'm not a big xml guy), but for me, running on fedora core 5, php 5.2.1
to get this to work, the cdata functions need to wrap the description (or whatever element the cdata should appear in)
for example.
// initiate xmlwriter object as $xw
// add header, titles, etc.
// start cdata
$xw->startCData();
// start description
$xw->startElement('description');
// write cdata
$xw->writeCData('<img src="http://php.net/images/php.gif" />');
// write the description contents
$xw->text('php logo');
// end the description element
$xw->endElement();
// end the cdata
$xw->endCData();
// end xml, and output
otherwise, i just got warnings about writing cdata in the wrong context, and no cdata would be written

A rather strange effect with this.
UTF8 Mysql database
$xml->startElement('tablecolor2');
$xml->writeCData( $tablecolor2 );
$xml->endElement();
does not work !
but
$xml->startElement('tablecolor2');
$tablecolor2 = utf8_decode ( $val['pcolor2']);
$xml->writeCData( utf8_encode ($tablecolor2) );
$xml->endElement();
cannot explain this - but it may help someone
