scandir-排序数字文件名 [英] scandir - sort numeric filenames

问题描述

做了一些搜索，但似乎找不到我要找的确切答案.

Done some searching, but can't seem to find the exact answer I'm looking for.

我想使用'scandir($ dir)'提取带有编号文件名的文件，但要使它们正确排序.例如，文件名是:

I'd like to pull in files with numbered filenames using 'scandir($dir)', but have them sort properly. For example, file names are:

1-something.ext

2-something-else.ext

3-a-third-name.ext

.

.

.

10-another-thing.ext

11-more-names.ext

我遇到的问题是10-a-fourththing.ext将在2-something-else.ext之前显示.我想找到一种解决此问题的更好方法，而不是在所有文件名前都添加前导"0".

The problem I'm having is that 10-a-fourth-thing.ext will show before 2-something-else.ext. I'd like to find a better way of solving this issue than introducing leading '0' in front of all file names.

有什么想法吗?谢谢.

推荐答案

natsort 完全满足您的需求.

natsort does exactly what you need.

sort也适用于以数字开头的文件名，但是如果前面也没有数字的名称会损坏(所有非数字前缀的名称将在数字前缀之前进行排序)名称及其相对的顺序将是随机的，而不是字母顺序.

sort with SORT_NUMERIC will also work for filenames that start with numbers, but it will break if there are also names that have no numbers in front (all non-number-prefixed names will be sorted before number-prefixed names, and their order relative to one another will be random instead of alphabetic).
