Question

我已将此代码全部正常工作。但是，按desc排序似乎不起作用？我希望列出的文件在顶部显示最新创建的文件。我不知道为什么它不是按desc订购的？

<?php
date_default_timezone_set('Europe/London');
$dirname = "dir1";
$dirnameTwo = "dir2";
$dirnameThree = "dir3";

$cam1 = scandir($dirname, 1);
$cam2 = scandir($dirnameTwo, 1);
$cam3 = scandir($dirnameThree, 1);
?>

                        if (file_exists($items[$i])) {
                            echo "</tr>";

   ");
                        if ($i === 12) break;
                    }
                    ?>
                </tr>
                </tbody>
            </table>
        </div>
    </div>
</div>
</body>
</html>

有人能解释为什么它不起作用吗？还是我把SORT_DESC放在错误的位置？

使用array_multisort（）按SORT_DESC排序不起作用
