如何排序的内部键期多维数组 [英] how to sort a multidemensional array by an inner key

问题描述

我有我从一个API拉战地叛逆连队2这个巨大的数组，士兵统计数据可以拉与每个士兵的内部数组多维数组，但是API sormats它通过排序士兵名称的字母顺序，我想通过等级对它们进行排序（这是战士阵列内只是一个键）。我一直试图弄清楚这一点的日子里，任何人有什么想法？
（即由$ ARR数组排序[玩家] [] [等级]

在这里是有点数组的

排列
（
    [玩家] =>阵列
        （
            [0] =>阵列
                （
                    [名] => bigjay517
                    [等级] => 29
                    [RANK_NAME] =>少尉II
                    [老将] => 0
                    [评分] => 979440
                    [等级] => 169
                    [杀] => 4134
                    [死亡] => 3813
                    [时间] => 292457.42
                    [ELO] => 319.297
                    【组成】=> 1
                    [date_lastupdate] => 2010-03-30T14：06：20 + 02：00
                    [count_updates] => 13
                    [普通] =>阵列
                        （
                            [精度] => 0.332
                            [dogr] => 86
                            [dogt] => 166
                            [elo0] => 309.104
                            [elo1] => 230.849
                            [游戏] => 384
                            [goldedition] => 0
                            [损失] => 161
                            [sc_assault] => 146333
                            [sc_award] => 567190
                            [sc_bonus] => 35305
                            [sc_demo] => 96961
                            [sc_general] => 264700
                            [sc_objective] => 54740
                            [sc_recon] => 54202
                            [sc_squad] => 53210
                            [sc_support] => 70194
                            [sc_team] => 21215
                            [sc_vehicle] => 44560
                            [slevel] => 0
                            [SPM] => 0
                            [spm0] => 0
                            [SPM1] => 0
                            [srank] => 0
                            [sveteran] => 0
                            [teamkills] => 67
                            [udogt] => 0
                            [胜] => 223
                        ）

解决方案

您可以使用 usort（排序任何条件任何数组）

i have this enormous array that i am pulling from an API for BattleField Bad Company 2, and the soldier stats can be pulled as a multi dimensional array with an inner array for each soldier, however the API sormats it sorting the soldiers by name alphabetically, i want to sort them by rank (which is just another key within that soldiers array). ive been trying to figure this out for days, anyone have any ideas? (ie sort the array by $arr[players][][rank]

here is a bit of the array

Array
(
    [players] => Array
        (
            [0] => Array
                (
                    [name] => bigjay517
                    [rank] => 29
                    [rank_name] => SECOND LIEUTENANT II
                    [veteran] => 0
                    [score] => 979440
                    [level] => 169
                    [kills] => 4134
                    [deaths] => 3813
                    [time] => 292457.42
                    [elo] => 319.297
                    [form] => 1
                    [date_lastupdate] => 2010-03-30T14:06:20+02:00
                    [count_updates] => 13
                    [general] => Array
                        (
                            [accuracy] => 0.332
