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>

This function will not have any effect if the last node you output was a text node.  This includes whitespace.  Example:



<?php

/*

<html>

<![CDATA[ Summut nice ]]>

<p>something</p>

</html>

*/

$xw = new XMLWriter;

$xw->openMemory();

$xw->startDocument('1.0', 'ISO-8859-1');

$xw->startElement('html');

$xw->text('Comment out this line to get the CDATA back!!');

$xw->writeCData('Summut nice');

$xw->writeElement('p', 'something');

$xw->endElement();

$xw->endDocument();

echo $xw->outputMemory();

?>

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

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
