    So really you can't rely on that. :)

true - although personally I always do if(is_array($r) && count($r)) in such cases. so it seems that there is inconsistency regardless of whether the warning is removed or not. out of interest what are the ramifications for SPL and simpleXML if the warning is not dropped?
