[Repost] Recursive Directory Iterator

This is my first time trying out the SPL iterators. Im trying to figure out how to recursively move over a directory. With the code that I've provided 1. Is this the correct way to use it? Im using recursive functions to go deep. I thought, that the class would do that for me somehow... 2. As it stands, it doesn't report the correct directory structure. For example, if I had a directory in the root with another directory under it, the second directory doesnt get echoed. Thanks ------ dirr('.'); function dirr($dir) { $dir = new RecursiveDirectoryIterator($dir); foreach($dir as $foo) {

       echo $foo->getPathname() . '<br />';

       if ($foo->hasChildren())
       {
           $bar = $foo->getChildren();

           foreach($bar as $foo2)
           {
                if ($foo2->hasChildren())
                {
                    dirr($foo2->getPathname());
                }
                else
                {
                    echo $foo2->getPathName() . '<br />';
                }
           }
       }

} }
