is_array() doesn't work on DOM properties?

I'm trying to avoid error messages while iterating over DOM properties. e.g. if(is_array($dom->stuff->props)) { foreach($dom->stuff->props as $prop) { ... } } It works without the is_array() check, but not with it. I've done var_dumps and $dom->stuff->props is indeed an array. I've also tried using an intermediate variable ($stuff=$dom->stuff) then checking that, but that doesn't work either).
