RecursiveDirectoryIterator and foreach

I have discovered that when I foreach over a RecursiveDirectoryIterator (see example below) the $item actually turns into a SplFileInfo object. I would expect it to be a RecursiveDirectoryIterator. How do I do a hasChildren() on SplFileInfo? However, if I change it to a non-recursive, DirectoryIterator, $item is what I would expect, DirectoryIterator. I've tested this with 5.2.8 and 5.3b1. I'm guessing this is an issue with my setup as I'm sure I've gotten this to work before... $dir = new RecursiveDirectoryIterator('/path/to/dir'); foreach ($dir as $item) {

    print get_class($item) . "\r\n";

}
