I believe related to this bug: on my machine (Mac OS X 10.4.9 Intel;
PHP 5.2.3/5.2-200707181030) I get a bus error if I do it with a
namespace, i.e.
$xml->child->addChild('grandchild','','whatever');
Exception: EXC_BAD_ACCESS (0x0001)
Codes: KERN_PROTECTION_FAILURE (0x0002) at 0x00000020
Thread 0 Crashed:

Description:
------------
addChild() does not behave as expected(?) when used on a node that
wasn't previously declared.
In the example below, we initialize an empty tree, to which we attempt
to add a new node at "/child/grandchild" without previously adding
"child" to the tree. addChild() seems to operate on a temporary
SimpleXMLElement and the changes are never applied to the original
object/tree.
I believe that this bug is also responsible of the segfault that
happens if getName() is used on the temporary SimpleXMLElement. I was
very tempted to file this bug as a reproducible crash, but decided to
file it under SimpleXML in case it would help routing it to the
maintainer faster.
Tested on:
PHP 5.2.4-dev (cli) (built: Jun 27 2007 20:04:30)
WinXP
libxml2 2.6.26
SimpleXML Revision: 1.151.2.22.2.29
PHP 5.2.2-pl1-gentoo (cli) (built: May 24 2007 00:26:35)
libxml 2.6.27
SimpleXML Revision: 1.151.2.22.2.26
Reproduce code:
---------------
<?php
$xml = simplexml_load_string('<?xml version="1.0" encoding="utf-8"
?><root />');
$xml->child->addChild('grandchild');
echo $xml->asXML();
Expected result:
----------------
I expect SimpleXML to create "child" if it does not exist, then add
"grandchild" to that node. The output should be:
<?xml version="1.0" encoding="utf-8"?>
<root><child><grandchild/></child></root>
Actual result:
--------------
Neither node is added to the tree. The output is:
<?xml version="1.0" encoding="utf-8"?>
<root/>
