if youre trying to do recursive iteration whereby you 'flatten' the tree
structure, drop the RecursiveDirectoryIterator into a
RecursiveIteratorIterator (its for iterating over RecursiveIterators), then
you dont have to bother w/ calling hasChildren() at all. you probly also
want to look at the constructor args, since by default, it only returns leaf
nodes.
$dir = new RecursiveDirectoryIterator('/path/to/dir');
$itt = new RecursiveIteratorIterator($dir,
RecursiveIteratorIterator::CHILD_FIRST);
