So, what you get is that the inherited DOMElement still exists in the DOM tree, but the subclass instance is gone. Reproduce code: --------------- <?php class Widget extends DOMElement { public function __construct() { parent::__construct('p'); } public function say() { echo "I am a widget!\n"; } } $doc = new DOMDocument(); $doc->appendChild($html = new DOMElement('html')); $html->appendChild($body = new DOMElement('body')); $body->appendChild(new Widget()); $body->firstChild->say(); ?> Expected result: ---------------- It should say: "I am a widget!". You can get this expected result by changing the line: $body->appendChild(new Widget()); to: $body->appendChild($widget = new Widget()); this way, the widget will not get out of scope and the actual class is remembered. Actual result: -------------- You will get an error saying: "Fatal error: Call to undefined method DOMElement::say() in testcase.php on line 17" ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=33450&edit=1
