Php 多级排序多维数组

伙计们，帮我做数组排序

我有一个数组：

Array
(
    [1] => Array
        (
            [pos] => 1
            [team_name] => Team1
            [tours] => Array
                (
                    [0] => Array
                        (
                            [tour_id] => 0
                            [tour_total] => 30
                        )

                    [1] => Array
                        (
                            [tour_id] => 1
                            [tour_total] => 31
                        )

                    [2] => Array
                        (
                            [tour_id] => 2
                            [tour_total] => 29
                        )

                    [3] => Array
                        (
                            [tour_id] => 3
                            [tour_total] => 0
                        )

                    [4] => Array
                        (
                            [tour_id] => 4
                            [tour_total] => 0
                        )

                    [5] => Array
                        (
                            [tour_id] => 5
                            [tour_total] => 0
                        )

                    [6] => Array
                        (
                            [tour_id] => 6
                            [tour_total] => 0
                        )

                    [7] => Array
                        (
                            [tour_id] => 7
                            [tour_total] => 0
                        )

                )

            [total] => 90
        )

    [2] => Array
        (
            [pos] => 2
            [team_name] => Team2
            [tours] => Array
                (
                    [0] => Array
                        (
                            [tour_id] => 0
                            [tour_total] => 30
                        )

                    [1] => Array
                        (
                            [tour_id] => 1
                            [tour_total] => 30
                        )

                    [2] => Array
                        (
                            [tour_id] => 2
                            [tour_total] => 30
                        )

                    [3] => Array
                        (
                            [tour_id] => 3
                            [tour_total] => 0
                        )

                    [4] => Array
                        (
                            [tour_id] => 4
                            [tour_total] => 0
                        )

                    [5] => Array
                        (
                            [tour_id] => 5
                            [tour_total] => 0
                        )

                    [6] => Array
                        (
                            [tour_id] => 6
                            [tour_total] => 0
                        )

                    [7] => Array
                        (
                            [tour_id] => 7
                            [tour_total] => 0
                        )

                )

            [total] => 90
        )

)

此数组包含团队按巡更的结果

我需要按“总计”值对该数组进行排序。如果相邻团队的值相等，则按第8轮的值排序（tour_id=7）。如果此处的值相等，则按巡更值7（巡更id=6）排序。等等。

我认为您应该为此使用

usort（）

函数。如果您使用的是PHP7或更高版本，则可以使用以下代码

  usort($array, function($a, $b) {
    return $a[tour_total] <=> $b[tour_total];
  });

或者您可以像下面这样使用

array\u multisort

array_multisort(array_map(function($element) {
      return $element['order'];
  }, $array), SORT_ASC, $array);

print_r($array);

它是否有助于

array\u multisort

功能：？

array_multisort(array_map(function($element) {
      return $element['order'];
  }, $array), SORT_ASC, $array);

print_r($array);
