Группируйте данные в многомерном массиве по столбцу внутри столбца и создавайте подмассивы внутри каждой группы. ⇐ Php

Мне нужно сгруппировать наборы данных из многомерного массива по значениям ['DispensaryInventory']['product_id'] (или ['Product']['id']) и сгруппировать их. данные в подмассивы для DispensaryInventory и ProductOption.
Мой массив:
$dispensary_inventory_data = [
[
'DispensaryInventory' => [
'id' => 15,
'dispensary_id' => 1,
'product_id' => 9,
'quantity' => '',
'price' => ''
],
'ProductOption' => ['value' => 2, 'unit' => 'oz'],
'Product' => ['id' => 9, 'name' => 'Bajaj']
],
[
'DispensaryInventory' => [
'id' => 11,
'dispensary_id' => 1,
'product_id' => 9,
'quantity' => 17,
'price' => 12.00
],
'ProductOption' => ['value' => '1/8', 'unit' => 'oz'],
'Product' => ['id' => 9, 'name' => 'Bajaj']
],
[
'DispensaryInventory' => [
'id' => 12,

Моя попытка кодирования:

if (isset($dispensary_inventory_data[$k1]["Product"]["id"])) {
