PHP Laravel将json结果重建为另一种json格式[关闭]

Question

can soeone help to modify the json result to another result format.

I have this json

{
  "_links": {...},
  "total": 10,
  "data": [
    {
      "_links": { ... },
      "id": 1,
      "name": "John Doe",
      "email": "[e-mail]",
      "images": [
        {
          "imageid": 12,
          "name": "Trees",
          "url":"http://path/of/image.jpg"
        },
        {
          "imageid": 13,
          "name": "People",
          "url":"http://path/of/image.jpg"
        },
      ]
    }
  ]
}

Then my goal is to achieve this kind of result:

{
  "_links": { ... },
  "total": 10,
  "data": [
    {
      "_links": { ... }
      "id": 1,
      "name": "John Doe",
      "email": "[e-mail]",
      "images": [
        {
          "12" : {
            "name":"Trees",
            "url":"http://path/of/image.jpg"
          },
          "13" : {
            "name":"People",
            "url":"http://path/of/image.jpg"
          }
        }
      ]
    }
  ]
}

SO basically on the second json I want the imageid to be a keyname inside the images object. I would like to collection in laravel instead of looping. something like:

collect($results)->each(function($value, $key){
   //code here...
});

Please help. Thanks

I got it to worked for now, but I'm not satisfied with my code because of the loop. if you guys have an idea to improve, please post your answer. Thanks.

Thanks to apokryfos for the idea in mapWithKeys().

$newArray = array();
foreach($result['data'] as $k => $v){
  $images = $v['images'];
  unset($v['images']);
  $keyed = collect($images)->mapWithKeys(function($item){
    $imageId = $item['imageid'];
    $data = [" $imageId" => [
      'name' => $item['name'],
      'url' =>  $item['url']
      ]];
    return $data;
  });

  $v = array_add($v, 'images', $keyed->toArray());
  array_push($newArray, $v);
}
