Understanding Ravel Multidimensional Array Value Extraction

There is an application currently under development at Ravel, and I would like to treat nested data as a single array, but I am having a hard time because I do not know how to do it.

The forms we want to achieve are as follows:
There are two data in the array below, but it is assumed that there are more than 100 data.
I'd like to turn it around in a loop, but if anyone knows, please advise me.

·Original data

array:2[
  0 = > array:3 [
    "id" = > "0 GPHKD"
    "target_layer" = > "Men and women in their teens (T-tier)"
    "key" = > array:2 [
      0 = > array:2 [
        "id" = > 10
        "product_name" = > "coffee"
      ]
      1 = > array:2 [
        "id" = > 9
        "product_name" = > "coffee mug"
      ]
    ]
  ]
  1 = > array:3 [
    "id" = > "0 GPHKC"
    "target_layer" = > "Men and women 20-34 years old (M1 F1 layer)"
    "key" = > array:2 [
      0 = > array:2 [
        "id" = > 10
        "product_name" = > "coffee"
      ]
      1 = > array:2 [
        "id" = > 9
        "product_name" = > "coffee mug"
      ]
    ]
  ]
]

·The form you want to realize

array:2[
  0 = > array:3 [
    "id" = > "0 GPHKD"
    "target_layer" = > "Men and women in their teens (T-tier)"
    "item_id1" = > "10"
    "product_name1" = > "coffee"
     "item_id2" = > "9"
    "product_name2" = > "coffee mug"
    ]
  ]
  1 = > array:3 [
    "id" = > "0 GPHKC"
    "target_layer" = > "Men and women 20-34 years old (M1 F1 layer)"
 　   "item_id1" = > "10"
    "product_name1" = > "coffee"
     "item_id2" = > "9"
    "product_name2" = > "coffee mug"
    ]
  ]
]

The easiest way is to create a new array using nesting loops.
For example, the code below.
Sample data:

$a=[
    [
      "id" = > "0 GPHKD",
      "target_layer" = > "Men and Women in their teens (T-tier),
      "key" = > [
        [
          "id" = > 10,
          "product_name" = > "coffee"
        ],
        [
          "id" = > 9,
          "product_name" = > "coffee mug"
        ]
      ]
    ],
    [
      "id" = > "0 GPHKC",
      "target_layer" = > "Men and women 20-34 years old (M1 F1 layer),
      "key" = > [
        [
          "id" = > 10,
          "product_name" = > "coffee"
        ],
        [
          "id" = > 9,
          "product_name" = > "coffee mug"
        ]
      ]
    ]
];

nesting loop:

$newList=[];
foreach($a as$key=>$val){
    $new=[
        "id" = > $val ["id" ],
        "target_layer" = > $val ["target_layer"],
    ];

    if(count($val["key"])>0){
        for($i=0;$i<count($val["key"]);$i++){
            $new["item_id".$i] = $val["key"][$i]["id"];
            $new["product_name".$i]=$val["key"][$i]["product_name"];
        }
    }

    array_push($newList,$new);
}

Results:

Array
(
    [0] =>Array
        (
            [id] = > 0 GPHKD
            [target_layer] =>Men and women in their teens (T-tier)
            [item_id0] = > 10
            [product_name0] = > Coffee
            [item_id1] =>9
            [product_name1] => Coffee mug
        )

    [1] =>Array
        (
            [id] = > 0 GPHKC
            [target_layer] => Men and women 20-34 years old (M1F1 layer)
            [item_id0] = > 10
            [product_name0] = > Coffee
            [item_id1] =>9
            [product_name1] => Coffee mug
        )

)
