如何创建PHP数组的汇总值？

Question

我如何做php数组的汇总值？

我想显示这样的结果。
DEVICE_1：LOW = 1，MEDIUM = 0，HIGHT = 0;
DEVICE_2：LOW = 2，MEDIUM = 0，HIGHT = 0;
DEVICE_3：LOW = 0，MEDIUM = 1，HIGHT = 2;

这是我的业务api服务的一些数据

Array
(
    [0] => Array
        (
            [0] => DEVICE_1
            [1] => LOW
            [2] => STAGE_1
        )

    [1] => Array
        (
            [0] => DEVICE_2
            [1] => LOW
            [2] => STAGE_1
        )

    [2] => Array
        (
            [0] => DEVICE_2
            [1] => LOW
            [2] => STAGE_2
        )

    [3] => Array
        (
            [0] => DEVICE_3
            [1] => MEDIUM
            [2] => STAGE_1
        )

    [4] => Array
        (
            [0] => DEVICE_3
            [1] => HIGHT
            [2] => STAGE_2
        )

    [5] => Array
        (
            [0] => DEVICE_3
            [1] => HIGHT
            [2] => STAGE_3
        )

)

你在哪里得到映射，例如LOW = 1?在内循环中用你的映射替换。

foreach ( $array as $device ) {
    $deviceInfo = '';
    foreach ( $device as $specs ) {
         $deviceInfo .= $specs . ' ';
    }
    echo $deviceInfo;
}
