Laravel：循环遍历数组并将其转换为修改后的数组，其中包含一个键中的原始数组

Question

I have a data array that contains food items and looks like this.

[
  {
    "itemId": 80001,
    "name": "FRENCH FRIES SMALL",
    "description": "More delicious than ever, our signature piping hot, thick cut Salted French Fries are golden on the outside and fluffy on the inside.",
    "price": 6,
    "slug": "french-fries-small-80001"
  },
  {
    "itemId": 80002,
    "name": "FRENCH FRIES MEDIUM",
    "description": "More delicious than ever, our signature piping hot, thick cut Salted French Fries are golden on the outside and fluffy on the inside.",
    "price": 7,
    "slug": "french-fries-medium-80002"
  },
  {
    "itemId": 80003,
    "name": "FRENCH FRIES LARGE",
    "description": "More delicious than ever, our signature piping hot, thick cut Salted French Fries are golden on the outside and fluffy on the inside.",
    "price": 8,
    "slug": "french-fries-large-80003"
  },
  {
    "itemId": 80052,
    "name": "CRINCKLE WEDGES SMALL",
    "description": "CRINCKLE WEDGES SMALL",
    "price": 7,
    "slug": "crinckle-wedges-small-80052",
    "sequence": 14
  },
  {
    "itemId": 80053,
    "name": "CRINCKLE WEDGES MEDIUM",
    "description": "CRINCKLE WEDGES MEDIUM",
    "price": 8,
    "slug": "crinckle-wedges-medium-80053",
    "sequence": 15
  },
  {
    "itemId": 80054,
    "name": "CRINCKLE WEDGES LARGE",
    "description": "CRINCKLE WEDGES LARGE",
    "price": 9,
    "slug": "crinckle-wedges-large-80054",
    "sequence": 16
  },

]

Now I have to loop through that array and if the name has either SMALL, MEDIUM, or LARGE I have to reformat the data so that it should look something like this e.g.

{
  "itemId": 80001,
  "name": "FRENCH FRIES",
  "description": "More delicious than ever, our signature piping hot, thick cut Salted French Fries are golden on the outside and fluffy on the inside.",
  "itemModifiers": [
    {
      "itemId": 80001,
      "name": "FRENCH FRIES SMALL",
      "description": "More delicious than ever, our signature piping hot, thick cut Salted French Fries are golden on the outside and fluffy on the inside.",
      "price": 6,
      "slug": "french-fries-small-80001"
    },
    {
      "itemId": 80002,
      "name": "FRENCH FRIES MEDIUM",
      "description": "More delicious than ever, our signature piping hot, thick cut Salted French Fries are golden on the outside and fluffy on the inside.",
      "price": 7,
      "slug": "french-fries-medium-80002"
    },
    {
      "itemId": 80003,
      "name": "FRENCH FRIES LARGE",
      "description": "More delicious than ever, our signature piping hot, thick cut Salted French Fries are golden on the outside and fluffy on the inside.",
      "price": 8,
      "slug": "french-fries-large-80003"
    }
  ],
  "slug": "french-fries-80001",
  "sequence": 8
}

The legacy system of the client was designed poorly and they are requiring an api that properly formats the data into a more granularized format. I was trying to figure out as to how do this. Please take note that the original array has more items than my example and I should loop through each one of them. Should I rebuild the data from scratch? Or is there a better way of doing this while looping through the array?

You could use Collections and do something like:

$data = collect(json_decode($data, true))
    ->map(function ($item) {
        return collect($item);
    })
    ->groupBy(function ($item) {
        return trim(str_replace(['SMALL', 'MEDIUM', 'LARGE'], '', $item['name']));
    })
    ->map(function ($items) {

        if ($items->count() > 2) {

            return $items;
        }

        $parent = $items->first()->except('price');
        $parent->put('itemModifiers', $items);

        return $parent;
    });

If you would prefer something a little shorter for the last map you could inline it :

->map(function ($items) {
    return $items->count() < 2 ? $items : $items->first()->except('price')->put('itemModifiers', $items);
});

Hope this helps!
