Changelog

Version Description
5.4.0 sorting_order constants were added. Any nonzero value caused descending order in previous versions. So for all PHP versions, use 0 for ascending order, and 1 for descending order. An option for SCANDIR_SORT_NONE behavior did not exist prior to PHP 5.4.0.

<?php
$dir    = '/tmp';
$files1 = scandir($dir);
$files2 = scandir($dir, 1);
