PHP 一行代码 二维数组指定字段排序

        foreach($countStats as $key => &$item) {
            if(!isset($unitNameMap[$item['unit_name']]) || !isset($expireDetection[$item['unit_name']])) {
                unset($countStats[$key]);
                continue;
            }
            $item = [
                'id'     => $item['unit_name'],
                'name'   => $unitNameMap[$item['unit_name']],
                'count'  => $item['count'],
                'expire' => $expireDetection[$item['unit_name']],
                'expire_rate' => $item['count'] <= 0 || $expireDetection[$item['unit_name']] <= 0 ? 0: (sprintf("%.2f",$expireDetection[$item['unit_name']] / $item['count'] * 100)),
            ];
        }

        array_multisort(array_column($countStats,'expire'),SORT_DESC,$countStats);

        return collection($countStats)->values();
