Bug #66411 [NEW]: RecursiveIterator and Countable don't work together

From: webmaster at johnatan dot ru Operating system: Debian 3.2.51-1 PHP version: 5.4.23 Package: SPL related Bug Type: Bug Bug description:RecursiveIterator and Countable don't work together Description: ------------ --- From manual page: http://www.php.net/countable.count --- If I implement Countable interface in class RecursiveIteratorIterator show only nodes with count(node) > 0. If I remove Countable interface show all nodes.
