如何在Laravel中从JSON索引计数 [英] How to index count from json in Laravel

问题描述

我有一个带有Structure的消息表，如下所示:

I have a messages table with Structure as follows:

• id sender_id接收者ID pet_id描述

说明是文本消息.我通过获取发件人是用户或收件人是用户的所有消息，然后按我想要的petId过滤它们，来获取与特定宠物相关的用户的消息.

the description is the text message. I am fetching messages of users related to a specific pet by fetching all messages where the sender is user or receiver is user and then filtering them by petId I want.

function messagesByPet($petId,$userId){
  $messages = Message::where('sender_id',$userId)->orWhere('receiver_id',$userId)->orderBy('created_at','asc')->get();
  $message = $messages->where('pet_id', $petId);
  return $message;
}

上面的函数有效，但是我收到的JSON如下.我不希望其中包含诸如"0"，"3"之类的索引.如何删除它们?

The above function works but the JSON I receive is as follows. I don't want indexes in it such as "0" "3". How to remove them?

{
  "0": {
    "id": 197,
    "sender_id": "5718",
    "receiver_id": "5716",
    "pet_id": "5113",
    "description": "Hi",
    "created_at": "2020-03-16 05:29:41",
    "updated_at": "2020-03-16 05:29:41"
  },
  "3": {
    "id": 203,
    "sender_id": "5718",
    "receiver_id": "5716",
    "pet_id": "5113",
    "description": "Hi",
    "created_at": "2020-03-18 22:06:40",
    "updated_at": "2020-03-18 22:06:40"
  }
}

推荐答案

在get()方法之后，您获得了集合.因此，您可以使用 values()方法返回包含键的新集合重置为连续的整数:

After get() method , you got the collection. So you can use values() method to returns a new collection with the keys reset to consecutive integers:

return $message->values();
