glob() — Sort by Name
提问by FrozenTime
How can I reverse the sort by filename? Currently it displays all the text files in alphabetical / numerical order, but I'm trying to have it display in descending order instead. Right now, I have...
如何按文件名反转排序？目前它以字母/数字顺序显示所有文本文件，但我试图让它以降序显示。目前，我有...
<?php
foreach (glob("*.txt") as $filename) {
include($filename);
}
?>
I'm pretty new to PHP, but I tried usort with array added on but that just resulted in it displaying only 1 of the text files, so either that doesn't work or I just coded it wrong.
我对 PHP 很陌生，但我尝试添加了数组的 usort 但这只是导致它只显示 1 个文本文件，所以要么不起作用，要么我只是编码错误。

You can use array_reverse:
您可以使用array_reverse：
foreach(array_reverse(glob("*.txt")) as $filename) { ...

Just a addition to @Foo Bah's answer :
When dealing with file names in a directory, I usually add natsortto prevent the typical ordering case :
只是对@Foo Bah 的回答的补充：在处理目录中的文件名时，我通常添加natsort以防止出现典型的排序情况：
- 'image1.png'
- 'image10.png'
- 'image2.png'
- 'image1.png'
- 'image10.png'
- 'image2.png'
natsortis a more user friendly sorting algorithm that will preserve natural numbering :
natsort是一种更加用户友好的排序算法，它将保留自然编号：
- 'image1.png'
- 'image2.png'
- 'image10.png'
- 'image1.png'
- 'image2.png'
- 'image10.png'
So FooBah's answer becomes :
所以 FooBah 的答案变成了：
$list = glob("*.jpg");
natsort($list);
foreach(array_reverse($list) as $filename) { ...
Please note that natsortis modifying the array passed in parameter and only returns a boolean.
请注意，这natsort是修改传入参数的数组，并且只返回一个布尔值。

As the glob()function sorts the filenames as default behaviour, you can simply loop through the resulting array in reverse order and therefore avoid any additional processing:
由于该glob()函数将文件名排序为默认行为，您可以简单地以相反的顺序循环遍历结果数组，从而避免任何额外的处理：
<?php
for($result = glob("*.txt"), $i = count($result); $i > 0; --$i) {
include($result[$i-1]);
}
?>
