如何通过内键对多维数组进行排序

我有一个巨大的数组，是从 BattleField Bad Company 2 的 API 中提取的，并且士兵统计数据可以作为多维数组提取，每个士兵都有一个内部数组，但是 API sormats 它按名称字母顺序对士兵进行排序，我想按等级对它们进行排序（这只是该士兵数组中的另一个键）。我已经尝试解决这个问题好几天了，有人有什么想法吗？ （即按 $arr[players][][rank] 对数组进行排序

这是数组的一部分

干得好。

$playergoop 是您提供的数组。

这个按子字段“排名”排序，但它是按升序排列的。如果您想要降序排列，可以将 > 切换为

function sorter($one, $two) {
    return ($one['rank'] > $two['rank']);
}

usort($playergoop['players'], sorter);
