AFAICT there's nothing in the DOM standard saying this should be the case (see https://dom.spec.whatwg.org/#dom-document-importnode). Test script: --------------- $original = new DOMDocument(); $original->loadHTML('<!DOCTYPE html>'); $docytpe = $original->doctype->cloneNode(); var_dump($doctype); // false $other = new DOMDocument(); $doctype = $other->importNode($original->doctype); var_dump($doctype); // false Expected result: ---------------- The result should be a new DocumentType node with the same name, publicId and systemId and, in the case of importNode, associated with the new document. ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=81682&edit=1
