Works for me on Linux... Can someone revalidate that on windows?
 [2004-07-26 12:33 UTC] tony2001@php.net
I can reproduce it with PHP 5.1.0-dev (cli) (built: Jul 26 2004 08:30:28) under Win2k.
 [2004-07-26 13:49 UTC] rrichards@php.net
I am unable to reproduce this under W2K and XP (using snaps and debug builds). Can someone who can reproduce this try var_dumping that vars after each line as well as doing a saveXML() on the doc each time to try to pinpoint where the problem lies. libxml version is irrelevant as I also tried from 2.5.11 - 2.6.11
 [2004-07-26 14:04 UTC] tony2001@php.net
Done.
Still using latest PHP-CLI from PHP5.1 snapshot under Win2k - sorry, no XP or any other Win32 system around here.

The code:
-----
<?
var_dump($doc = new DOMDocument("1.0"));
echo $doc->saveXML();
var_dump($root = $doc->createElement("HTML"));
echo $doc->saveXML();
var_dump($root = $doc->appendChild($root));
echo $doc->saveXML();
var_dump($head = $doc->createElement("HEAD"));
echo $doc->saveXML();
var_dump($head = $root->appendChild($head));
echo $doc->saveXML();
var_dump($title = $doc->createElement("TITLE"));
echo $doc->saveXML();
var_dump($title = $head->appendChild($title));
echo $doc->saveXML();
var_dump($text = $doc->createTextNode("This is the title"));
echo $doc->saveXML();
var_dump($text = $title->appendChild($text));
echo $doc->saveXML();
?>
-----

The output:
-----
object(DOMDocument)#2 (0) {
}
<?xml version="1.0"?>
object(DOMElement)#3 (0) {
}
<?xml version="1.0"?>
object(DOMElement)#3 (0) {
}
<?xml version="1.0"?>
<HTML/>
object(DOMElement)#4 (0) {
}
<?xml version="1.0"?>
<HTML/>
object(DOMElement)#4 (0) {
}
<?xml version="1.0"?>
<HTML/>
object(DOMElement)#5 (0) {
}
<?xml version="1.0"?>
<HTML/>
object(DOMElement)#5 (0) {
}
<?xml version="1.0"?>
<HTML/>
object(DOMText)#6 (0) {
}
<?xml version="1.0"?>
<HTML/>
object(DOMText)#6 (0) {
}
<?xml version="1.0"?>
<HTML/>
-----

The same code under Linux outputs this:
-----
object(DOMDocument)#1 (0) {
}
<?xml version="1.0"?>
object(DOMElement)#2 (0) {
}
<?xml version="1.0"?>
object(DOMElement)#2 (0) {
}
<?xml version="1.0"?>
<HTML/>
object(DOMElement)#3 (0) {
}
<?xml version="1.0"?>
<HTML/>
object(DOMElement)#3 (0) {
}
<?xml version="1.0"?>
<HTML><HEAD/></HTML>
object(DOMElement)#4 (0) {
}
<?xml version="1.0"?>
<HTML><HEAD/></HTML>
object(DOMElement)#4 (0) {
}
<?xml version="1.0"?>
<HTML><HEAD><TITLE/></HEAD></HTML>
object(DOMText)#5 (0) {
}
<?xml version="1.0"?>
<HTML><HEAD><TITLE/></HEAD></HTML>
object(DOMText)#5 (0) {
}
<?xml version="1.0"?>
<HTML><HEAD><TITLE>This is the title</TITLE></HEAD></HTML>
-----

I could try it with Win32 debug build too, if you tell me where I can get it.

Check your php.ini file and see if zend.ze1_compatibility_mode = On also change error_reporting to: error_reporting  =  E_ALL|E_STRICT

run it again, then if compat was on, change to off and run again.

 [2004-07-26 14:22 UTC] tony2001@php.net
Yep, it was On. Turning it Off solves the problem.

With compatibility On and error_reporting E_ALL|E_STRICT the code outputs:
