多维数组按字符串排序 [英] multi dimensional array sorting by string

问题描述

我要弄清楚如何正确地做到这一点，我有这个多维数组:

I'm breaking my head trying to figure out how to do this right, I have this multi dimensional array:

Array
(
    [0] => Array
        (
            [time] => November 1st 10:10
            [query] => movies
            [set] => 1
            [matches] => No matching results
            [results] => 5
        )

    [1] => Array
        (
            [time] => November 1st 10:10
            [query] => cinemas
            [set] => 1
            [matches] => No matching results
            [results] => 2
        )

)

在现实生活中，可能会有更多的子数组，但是有人说我想按字母查询"对它进行排序，我该如何实现呢?

In real life, there could be alot more sub-arrays, but et's say I want to sort it by "query" alphabetically, how can I achieve this?

我只看到整数类型或键索引的解决方案，在这种情况下，最终结果将是:

I saw only solutions for integer type or key index, the end result, in this case, would be:

Array
    (
        [0] => Array
            (
                [time] => November 1st 10:10
                [query] => cinemas
                [set] => 1
                [matches] => No matching results
                [results] => 2
            )
        [1] => Array
            (
                [time] => November 1st 10:10
                [query] => movies
                [set] => 1
                [matches] => No matching results
                [results] => 5
            )

    )

非常感谢，谢谢.

推荐答案

function querySort ($x, $y) {
    return strcasecmp($x['query'], $y['query']);
}

usort($myArray, 'querySort');
