PHP Code:

<?php

        function permission($filename)
        {
            $perms = fileperms($filename);

            if     (($perms & 0xC000) == 0xC000) { $info = 's'; }
            elseif (($perms & 0xA000) == 0xA000) { $info = 'l'; }
            elseif (($perms & 0x8000) == 0x8000) { $info = '-'; }

            return $info;
        }

        function dir_list($dir)
        {
            if ($dir[strlen($dir)-1] != '/') $dir .= '/';

            if (!is_dir($dir)) return array();

            $dir_handle  = opendir($dir);
            $dir_objects = array();
            while ($object = readdir($dir_handle))

If you want to sort the array by time you need to use the creation time as indexes. You can do this by modifying just one function in the function dclamp posted:

Code:

---

$dir_objects[filectime($filename)] = $file_object;

---

You can now sort the contents of the array using ksort() for ascending and krsort() for descending. Obviously, the first / last element of the array depending in the function you use will be the latest file.
