The difficulty is that it depends on the intention of the caller. Should they pass in a directory and if so - should it remove this directory. As the routine is called rrmdir I would sort of expect it to remove the directory I was passing in.

function rrmdir($dir)
{
    echo $dir.PHP_EOL;
    if (is_dir($dir))
    {
        $objects = scandir($dir);
        foreach ($objects as $object)
        {
            if ($object != "." && $object != "..")
            {
                echo $object.'='.filetype($dir."/".$object).PHP_EOL;
                if (filetype($dir."/".$object) == "dir") {
                    rrmdir($dir."/".$object);
                    rmdir($dir);
                }
                if (filemtime($dir."/".$object) <= time()-60*60*24) unlink($dir."/".$object);

            }
        }
        reset($objects);
        //rmdir($dir);
    }
}

I've moved the rmdir into the test for sub-directories. It was previously removing all directories (including the one passed in).
