用php中的特殊字符对多维数组进行排序 [英] Sort multidimensional array with special characters in php

问题描述

我有一个多维数组，按字母顺序排序，但是问题是丹麦特殊字符æøå.它们应按该顺序排序，但不按该顺序返回.

I have a multidimensional array, that I'm sorting alphabetically, but problem is, with danish special characters æ ø å. They should be sorted in that order, but is not returned in that order.

这是我的数组(部分数组已删除)

This is my array (part of is removed)

Array
(
    [0] => Array
        (
            [Name] => John
        )

    [1] => Array
        (
            [Name] => Pater
        )

    [2] => Array
        (
            [Name] => Allan

        )
    [3] => Array
        (
            [Name] => Ø test

        )
    [4] => Array
        (
            [Name] => Å test

        )
    [5] => Array
        (
            [Name] => Æ test

        )
)

我正在使用此功能对其进行排序

I'm using this function to sort it

uasort($sorted_region, function($a, $b) {
    $retval = $a['Name'] <=> $b['Name'];
    return $retval;
});

任何人都知道，如何对它进行排序，所以我以正确的顺序得到æøå?

Anyone know, how to sort it, so I get æ ø å in the right order?

例如，我已经看到一些使用

I've seen some using e.g.

setlocale(LC_COLLATE, 'da_DK.utf8');
asort($array, SORT_LOCALE_STRING);

但是我不确定如何在多维数组中实现它.

But I'm not sure how to implement this in a multidimensional array.

感谢您的帮助！ :-)

Thanks for any help! :-)

推荐答案

实际上这似乎可行

setlocale(LC_ALL, 'da_DK.utf8');

usort($sorted_region, function($a, $b) {
    return strcoll($a['Name'], $b['Name']);
});
