This does not happen if you use the functional COM interface. This will leak: $xml = new COM("MSXML.DOMDocument"); $element = $xml->createElement("test"); $element->text = str_repeat("this is a text string!", 100); $element->Release(); $xml->Release(); but this doesn't: $xml = new COM("MSXML.DOMDocument"); $element = com_invoke($xml, "createElement", "test"); com_set($element, "text", str_repeat("this is a text string!", 100)); com_release($element); $xml->Release(); ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=19150&edit=1
