I am trying to add a CDATA section to a DOMdocument.
Code:
<?php
// Create a DOMDocument object and set nice formatting
$doc = new DOMDocument( "1.0", "UTF-8" );
$doc->formatOutput = true;
// Create the root "stockList" element
$stockList = $doc->createElement( "stockList" );
$doc->appendChild( $stockList );
// Create the first "item" element (apple)
$item = $doc->createElement( "item" );
$item->setAttribute( "type", "fruit" );
$stockList->appendChild( $item );
// Create the item's "description" child element
$description = $doc->createElement( "description" );
$item->appendChild( $description );
$cdata = $doc->createCDATASection( "Apples are <b>yummy</b>" );
$description->appendChild( $cdata );
// Create the second "item" element (beetroot)
$item = $doc->createElement( "item" );
$item->setAttribute( "type", "vegetable" );
$stockList->appendChild( $item );
echo $doc->saveXML();
?>
What I'm expecting to see is Apples are yummy, with yummy in bold.
Here's what I get:
yummy]]>
Firebug / Edit gives me this:
<stocklist>
<item type="fruit">
<description><!--[CDATA[Apples are <b-->yummy]]></description>
</item>
<item type="vegetable">
</item></stocklist>
What I'm expecting is:
<stocklist>
<item type="fruit">
<description><![CDATA[Apples are <b->yummy</b>]]></description>
</item>
<item type="vegetable">
</item></stocklist>
Any ideas?

I'm not really sure why you'd expect that dash in <b->, but at any rate,
running your code on a current PHP 5.3 build results in what I'd expect,
which is:
<?xml version="1.0" encoding="UTF-8"?>
<stockList>
<item type="fruit">
<description><![CDATA[Apples are <b>yummy</b>]]></description>
</item>
<item type="vegetable"/>
</stockList>
What version of PHP are you running?

You are getting the expected output, you are just not viewing it
properly. You need to add the appropriate Content-Type header so the
browser knows it is an XML document:
header('Content-Type: text/xml; charset=UTF-8');
Otherwise, the server will send the default type, which is probably
text/html.

That panel does not display the original source code but and an
interpretation of it. In this case, the code misinterpreted as HTML and
fixed to fit.
Use the browser's "View source" feature instead (or run the script from
the command line).

PHP is not the issue here, but that the OP has not understood what XML is
(and how it is to be used), what a CDATA section is (that its content is
*not* parsed except for `]]>', and so cannot possibly display bold because
of <b>…</b> in it), and that Firebug's innerHTML-based Edit feature is shaky
at best with XML documents served as text/html.
Something along
header('Content-Type: text/xml; charset=UTF-8');
is missing after
<?php
but that would still not display anything of the markup in bold. (And that
is good so.)

That was a a typo when I copied it. I am expecting <b>. When I run
phpinfo() it tells me that the PHP version is 5.3.4

Perhaps you should read the post before making up assumptions about
the OP. Where did I say that I'm expecting to see bold? I am pointing
to the generated XML code, not how the generated code is displayed.
Why would I expect anything in a CDATA section to be displayed?

I really do not have to make assumptions in this case. It is very obvious
that you do not know what you are doing.
> Where did I say that I'm expecting to see bold?
In your OP. Precisely:
>>> What I'm expecting to see is Apples are yummy, with yummy in bold.
> I am pointing to the generated XML code, not how the generated code is
> displayed.
Then you should have said so. XML is not (X)HTML; a `b' element has no
inherent meaning there. And when `<b>…</b>' is in a CDATA section, it does
not constitute an element at all.
> Why would I expect anything in a CDATA section to be displayed?
You should expect the content of a CDATA section to be displayed verbatim
because that is how it works. You are not expecting it because evidentially
you have not understood what a CDATA section is, and how XML works.
Please trim your quotes to the relevant minimum.

So, you've decided that the only legitimate use of CDATA is what your
blinders point you to. If it has not occurred to you yet, there are
possible uses for an XML/XHTML structure other than being viewed
through a web browser. Please trim your ego and insults to the
relevant minimum.
