Note Submitter: badbrush at pixtur dot de ---- another WARNING about report #26396 having status "wont fix": Beware of using foreach in recursive functions like... function sort_folders(&$items, $parent,$level) { foreach($items as $item) { if($item->parent == $parent) { print $item; // call recursively... sort_folders(&$items, $item, $level+1); } } } I struggled a few hours with this code, because I thought the passing the array by reference would be the problem. Infact you can only have ONE foreach for an array at any given time. A foreach inside another foreach does not work. The manual should definately give some hints about this behaviour. pixtur
