将多维数组合并为一个单一数组

Question

很抱歉标题可能不够清晰。我有以下已调试的数组:

Array

    [output] => Array
        (
            [0] => Array
                (

                                    [level] => 1
                                    [item_id] => 227
                                    [subpart_id] => 227
                                    [subpart_name] =>

                                    [dates] => Array
                                        (
                                            [2015-12-04] => 500
                                            [2015-12-03] => 500
                                            [2015-12-02] => 500
                                            [2015-12-01] => 500
                                            [2015-11-30] => 500
                                        )

                                )

                        )

                    [dates] => Array
                        (
                            [0] => Array
                                (
                                    [delivery_date] => 2015-12-18
                                    [qty] => 1000
                                )

                            [1] => Array
                                (
                                    [delivery_date] => 2015-12-21
                                    [qty] => 200
                                )

                        )

                )

        )

    [min_date] => 2015-11-25
    [max_date] => 2015-12-21
)

正如您所看到的，两个数组元素除了$routes[ROUTE_NAME][dates]中的日期外，其他完全相同，我希望将那些值合并成一个值，这样就只有一个值，当然除了日期不同。

例如，ROUTE_NAME（如227-DELIVERY）的输出。

[227-DELIVERY] => Array
(
    [line_name] => Distribution
    [pid] => 48
    [rid] => 605
    [level] => 1
    [item_id] => 227
    [subpart_id] => 227
    [subpart_name] => + 1PA-E5514-00
    [selected_capacity] => 1500
    [capacity] => 1500
    [capacity_ot2] => 0
    [capacity_ot4] => 0
    [dates] => Array
        (
            [2015-12-15] => 1200
            [2015-12-16] => 1200
        )

)

是否有内置的PHP函数可以实现这个功能？我认为array_merge_recursive无法实现此功能。

你可以尝试类似的方法：https://dev59.com/Gmw15IYBdhLWcg3wLIo2 - Scream

array_merge_recursive 在这种情况下可能会很麻烦，但是简单的 array_merge 结合 foreach 就可以解决。这将创建一个新的数组 $result，其中包含合并的数据：

$result = array();
foreach($array['output'][0]['routes'] as $key => $route){
    $route['dates'] = array_merge($route['dates'], $array['output'][1]['routes'][$key]['dates']);
    $result[$key] = $route;
}

print_r($result);

如果你想把所有东西放到同一个数组中，可以这样做：

foreach($array['output'][0]['routes'] as $key => &$route){
    $route['dates'] = array_merge($route['dates'], $array['output'][1]['routes'][$key]['dates']);
}

print_r($array['output'][0]['routes']);

在foreach循环中注意&，它基本上告诉我们修改正在遍历的现有数组。
