It seems, that ZendEngine2 breaks create_element() behavior. This method returns NULL instead of DomElement object.

There is my test code.

<?php
$doc = domxml_new_doc("1.0");
$root = $doc->create_element("xdocument");
$root = $doc->append_child($root);
$descr = $doc->create_element("description");
$descr = $root->append_child($descr);

print $doc->dump_mem();
?>

I got the same problem also. I'm using ZendEngine2 (PHP4.3.0_zend2_alpha3). Following are my two test cases.

1. $elm = new DomElement("element"); 
It returns an DomElement object with NO property. I traced the source code, found that the internal constructor function domxml_doc_create_element() was not invoked. 

2. $elm = $doc->create_element("element"); 
The method returns NULL. Furthermore, the internal function domxml_doc_create_element() applied on the wrong object $doc instead of $elm ($doc's type changed to XML_ELEMENT_NODE, previously it was XML_DOCUMENT_NODE ). Dump of $doc is like this:
domdocument Object
(
    [name] => #document
    [url] => 
    [version] => 1.0
    [standalone] => -1
    [type] => 1
    [compression] => -1
    [charset] => 1
    [0] => 2
    [1] => 136550520
    [tagname] => element
)

Above bugs exist in all Dom* classes and create_* methods.

After I compiled php4 with zend1.3.0, above test cases passed, everything became OK. So I believe it is some kind of bug within ZendEnging2.

This problem exists under my setup of PHP 5.0.5, its associated php_domxml.dll module for the same version of PHP, and Windows XP Professional served under Apache 2.0.54. create_element() as well as create_element_ns() return NULL, without so much as a notice. In fact, I have never been able to get it to return anything but NULL.

Another example, even simpler, that reproduces the error:
<?php
	$doc = domxml_new_doc("1.0");
	$root = $doc->create_element("notifications");
	
	echo "<pre>";
	var_dump($root);
	echo "</pre>";
?>
The output is "NULL."

I have the same problem on Apache 2.0.59 with PHP 5.2.1 on Widnows XP 32 bit.
