glob()-按日期排序 [英] glob() - sort by date

问题描述

我正在尝试按日期顺序显示文件数组(最后修改).

I'm trying to display an array of files in order of date (last modified).

我已经完成了遍历数组并将其排序到另一个数组中的购买，但是有没有更简单(更有效)的方法来做到这一点?

I have done this buy looping through the array and sorting it into another array, but is there an easier (more efficient) way to do this?

推荐答案

从PHP 7.2.0开始，

警告 create_function()已被废弃.强烈建议不要使用此功能.

Warning create_function() has been DEPRECATED as of PHP 7.2.0. Relying on this function is highly discouraged.

为了后代，万一在接受的答案中链接的论坛帖子丢失或不清楚，则所需的相关代码为:

For the sake of posterity, in case the forum post linked in the accepted answer is lost or unclear to some, the relevant code needed is:

<?php

$myarray = glob("*.*");
usort($myarray, create_function('$a,$b', 'return filemtime($a) - filemtime($b);'));

?>

在我的系统上对此进行了测试，并验证了它确实可以根据需要对文件mtime进行排序.我也使用类似的方法(用Python编写)来确定网站上的最新更新文件.

Tested this on my system and verified it does sort by file mtime as desired. I used a similar approach (written in Python) for determining the last updated files on my website as well.
