Description:
------------
hi, test this:

header("Content-Type: text/plain");

$doc = new \DOMDocument()
$doc->appendChild($doc->createElement("root", NULL));
echo $doc->saveXML();

echo "\n\nshould be equivalent to:\n\n";

$doc = new \DOMDocument()
$doc->appendChild($doc->createElement("root"));
echo $doc->saveXML();

i hope other DOM methods will work good... otherwise fix is needed

thank you!

They're not equivalent: you're providing a value for the "value"
parameter to DOMDocument::createElement(), so yes, it will get coerced
into an empty string using PHP's usual type juggling mechanism.

i don't think that is like you think

if i extend appendChild


override appendChild($name, $content = NULL, $myNewArg = NULL)

if i want to skip the second argument i can not

or another issue:

as php doc says

DOMImplementation->createDocument  ([  string $namespaceURI = NULL  [,  string $qualifiedName = NULL  [,  DOMDocumentType $doctype = NULL  ]]] )

third parameter is optional (=NULL)

but if i do

$x->createDocument(null, null, null); to create an empty document 

exception is thrown:

Argument 3 passed to DOMImplementation::createDocument() must be an instance of DOMDocumentType, null given

if i do createDocument(); obviously works, but the concept of "skipping not required parameters with null" is not respected
