有人可以解释 ResourceCollection 和 JsonResource 之间的区别吗？

在 Laravel 6 文档中，您可以生成 2 种不同类型的资源……ResourceCollection 和 JsonResource。 https://laravel.com/docs/6.x/eloquent-resources#resource-responses

<?php

namespace App\Http\Resources;

use Illuminate\Http\Resources\Json\ResourceCollection;

class ShopCollection extends ResourceCollection
{
    /**
     * Transform the resource collection into an array.
     *
     * @param  \Illuminate\Http\Request  $request
     * @return array
     */
    public function toArray($request)
    {
        return parent::toArray($request);
    }
}

对...

<?php

namespace App\Http\Resources;

use Illuminate\Http\Resources\Json\JsonResource;

class Shop extends JsonResource
{
    /**
     * Transform the resource into an array.
     *
     * @param  \Illuminate\Http\Request  $request
     * @return array
     */
    public function …

如何：将 Laravel 集合折叠成逗号分隔的字符串？

dd($ids);

Illuminate\Support\Collection {#538 ?
  #items: array:463 [?
    0 => 30578786410269
    1 => 30578326028621
    2 => 30788548304669
    3 => 30788548607437
    4 => 30788592370221
    5 => 30788592672989
    6 => 30788592975757
    7 => 30492511411997
      ]
}

我如何把它变成一个像这样的字符串？：

30578786410269,30578326028621,30788548304669,30788548607437,30788592370221,30788592672989,30788592975757,30492511411997
