Laravel 集合所在索引

Question

我下面有这个合集

[
   {
      "id":"6ad91b63-d964-4155-b16a-47fc246b6aa3",
      "content":"",
      "to":[
         "6ea94472-7db6-4d66-a485-30f99d46d039",
         "37c61b0b-2b75-4652-9ee9-b8d54fde3fe9",
         "335e9ee7-02ff-494d-89e9-b69b76d0504b",
         "7f67f3aa-7fdf-461c-aaf9-90293067363f",
         "a30477c8-256c-4ba8-aa69-22d7190516dd"
      ],
      "type":"berita",
      "created_by":"363b75f2-8f01-422d-a3cb-ea501d9b5edd",
      "created_at":"2022-01-12T18:22:51.000000Z",
      "updated_at":"2022-01-12T18:23:47.000000Z"
   }
]

我想按“to”列查找，其中“to”是我定义的值。我试图使用 where collection 但仍然一无所获。这是我的 eloquent 电话

$feed = Feed::latest()
             ->get()
             ->where('to','a30477c8-256c-4ba8-aa69-22d7190516dd');

Answer 1

您可以直接使用 filter（where 使用）：

$collection->filter(fn ($item) => in_array('a30477c8-256c-4ba8-aa69-22d7190516dd', $item->to))
