排序Mulitdemensional阵列PHP [英] Sorting Mulitdemensional Array PHP

问题描述

我有以下的阵列，它目前的创entity_count排序。（在CakePHP中做了查询输出 - 我只是想排在前几位的实体），我想现在对于实体 - 阵列>标题排序

我试图与在array_multisort 这样做，但失败了。这可能吗？

 阵列
（
    [0] =＆GT;排列
        （
            [实体] =＆GT;排列
                （
                    [标题] =＆GT;橙子
                ）            [0] =＆GT;排列
                （
                    [entitycount] =＆GT; 76
                ）        ）    [1] =＆GT;排列
        （
            [实体] =＆GT;排列
                （
                    [标题] =＆GT;苹果
                ）            [0] =＆GT;排列
                （
                    [entitycount] =＆GT; 78
                ）
        ）
    [2] =＆GT;排列
        （
            [实体] =＆GT;排列
                （
                    [标题] =＆GT;柠檬
                ）            [0] =＆GT;排列
                （
                    [entitycount] =＆GT; 85
                ）
        ）
）
 

解决方案

创建一个回调函数，像这样：

 回调函数（$值）
{
    返回使用isset（$值['实体'] ['标题']）？ $值['实体'] ['标题']：空;
}
 

然后运行它thew一个array_map和多类

 在array_multisort（array_map（$ myArray的，'回调'），$ myArray的）;
 

I have the following array, it is currently created sorted by entity_count (outputted by a query done in cakephp - I only wanted the top few entities), I want to now sort the array for the Entity->title.

I tried doing this with array_multisort but failed. Is this possible?

Array
(
    [0] => Array
        (
            [Entity] => Array
                (
                    [title] => Orange
                )

            [0] => Array
                (
                    [entitycount] => 76
                )

        )

    [1] => Array
        (
            [Entity] => Array
                (
                    [title] => Apple
                )

            [0] => Array
                (
                    [entitycount] => 78
                )
        )
    [2] => Array
        (
            [Entity] => Array
                (
                    [title] => Lemon
                )

            [0] => Array
                (
                    [entitycount] => 85
                )
        )
)

解决方案

Create a callback function like so:

function callback($value)
{
    return isset($value['entity']['title']) ? $value['entity']['title'] : null;
}

Then run it thew an array_map and multi sort

array_multisort(array_map($myArray,'callback'), $myArray);
