Как я могу сделать универсальную функцию, чтобы уменьшить вложенный объект в массив стиля CSV?

Question

Я пытаюсь выяснить, как я могу сгладить вложенный массив / дерево в формате стиля CSV.

У меня есть результат от упругого поиска, который выглядит следующим образом (примечание - каждое свойство 'buckets' может иметь несколько или 0 элементов):

$data = array(
'reeta.datetime_day' => array(
    'buckets' => array(
        0 => array(
            'key_as_string' => '2018-07-27T00:00:00.000Z',
            'key' => 1532649600000,
            'doc_count' => 4,
            'ticket.employee_name' => array(
                'doc_count_error_upper_bound' => 0,
                'sum_other_doc_count' => 0,
                'buckets' => array(
                    0 => array(
                        'key' => 'Era Swift',
                        'doc_count' => 3,
                        'ticket.order_type' => array(
                            'doc_count_error_upper_bound' => 0,
                            'sum_other_doc_count' => 0,
                            'buckets' => array(
                                0 => array(
                                    'key' => 'Dine In',
                                    'doc_count' => 3,
                                    'ticket.total_guest_count' => array(
                                        'value' => 17,
                                    ) ,
                                    'ticket.total_revenue' => array(
                                        'value' => 273,
                                    ) ,
                                ) ,
                            ) ,
                        ) ,
                    ) ,
                    1 => array(
                        'key' => 'Dorothea Friesen',
                        'doc_count' => 1,
                        'ticket.order_type' => array(
                            'doc_count_error_upper_bound' => 0,
                            'sum_other_doc_count' => 0,
                            'buckets' => array(
                                0 => array(
                                    'key' => 'Take Out',
                                    'doc_count' => 1,
                                    'ticket.total_guest_count' => array(
                                        'value' => 2,
                                    ) ,
                                    'ticket.total_revenue' => array(
                                        'value' => 195,
                                    ) ,
                                ) ,
                            ) ,
                        ) ,
                    ) ,
                ) ,
            ) ,
        )
    )
)

);

У меня есть список измерений и метрик, которые я использую для получения этих агрегаций, и они различаются, например, для приведенного выше результата используется следующее:

$dimensions = ['reeta.datetime_day', 'ticket.employee_name', 'ticket.order_type'];
$metrics = ['ticket.total_guest_count', 'ticket.total_revenue'];

Я бы хотел, чтобы это было что-то вроде:

$result = [
    // the first bucket of the deepest dimension (ticket.order_type)
    [
        1532649600000, // the first dimensions key value
        'Era Swift', // the second dimensions key value
        'Dine In', // the thirs dimensions key value
        17, // the first metrics value
        273 // the second metrics value
    ],
    // the second bucket of the deepest dimension (ticket.order_type)
    [
        1532649600000, // the first dimensions key value
        'Dorothea Friesen', // the second dimensions key value
        'Take Out', // the thirs dimensions key value
        2, // the first metrics value
        195 // the second metrics value
    ],
];

Чтобы лучше объяснить мой вариант использования, я создал API, который принимает ряд измерений и метрик, а затем запрашивает ES для получения результатов. Затем я беру эти результаты и использую их для создания таблиц данных для Google Charts (https://developers.google.com/chart/interactive/docs/datatables_dataviews).

Я пытался написать много рекурсивных функций, array_walk_recursive и т. Д., И пробовал поискать в Google для любого подобного примера, но нигде не могу его найти.

Я попытался пройти и проверить:

$array[$dimension]['buckets']

Чтобы знать, что я был на самом глубоком уровне, когда индекс не существовал в сочетании с Динамический доступ к значению многомерного массива

Но я всегда получаю неправильные результаты. Я просто не могу просто сгладить массив, так как мне нужен элемент массива для каждого сегмента самого глубокого уровня.

Надеюсь, это имеет какой-то смысл, но я буду рад уточнить и получить больший набор данных здесь: https://pastebin.com/mU2xkQGB

Если бы кто-нибудь мог указать мне правильное направление или какие-либо примеры чего-то отдаленно похожего, что было бы очень цениться, у меня действительно было несколько вложенных блоков foreach, работающих в какой-то момент, но как только я изменю количество измерений, конечно это не сработало.

Answer 1

Мне удалось найти одно решение, оно определенно не самое лучшее, но оно работает в общем для любого количества измерений и метрик.

По сути, я построил объект дерева, используя https://github.com/nicmart/Tree, и поэтомумог пересекать узлы, но я хотел, чтобы каждый раз, добавляя метрики, я мог вернуться обратно к его родителям и создать для него строку таблицы.

См. рабочий код ниже:

composer require nicmart/tree

И это файл
