按给定键对 Laravel 集合进行分组

Question

在 Laravel 中，如果同一用户数组有多个响应，我想更改响应

我通过此功能得到了回复

控制器.php

public function index(){
    $reports = Report::all();
    return $this->sendResponse($reports->toArray(), 'User Reports successfully.');
}

这是我的回应

{
    "success": true,
    "data": [
        {
            "id": 66,
            "cuid": 20,
            "name": "my1",
            "created_at": "2018-03-09 00:00:00",
            "updated_at": "2018-03-09 00:00:00",
            "time": "07:19 PM",
            "status": "D"
        },
        {
            "id": 65,
            "cuid": 20,
            "name": "my1",
            "created_at": "2018-03-07 00:00:00",
            "updated_at": "2018-03-07 00:00:00",
            "time": "07:39 PM",
            "status": "D"
        },
        {
            "id": 64,
            "cuid": 21,
            "name": "my2",
            "created_at": "2018-03-02 00:00:00",
            "updated_at": "2018-03-05 00:00:00",
            "time": "07:01 PM",
            "status": "D"
        },
        {
            "id": 63,
            "cuid": 20,
            "name": "my2",
            "created_at": "2018-03-02 00:00:00",
            "updated_at": "2018-03-02 00:00:00",
            "time": "06:44 PM",
            "status": "D"
        }     
    ],
    "message": "User Reportsssss successfully."
}

这很好，我的问题是我有 4 个数组，其中有 2 个用户插入显示，我想这样显示

{
    "success": true,
    "data": [
        my1:{
                {
                    "id": 66,
                    "cuid": 20,
                    "name": "my1",
                    "created_at": "2018-03-09 00:00:00",
                    "updated_at": "2018-03-09 00:00:00",
                    "time": "07:19 PM",
                    "status": "D"
                }
                {
                    "id": 65,
                    "cuid": 20,
                    "name": "my1",
                    "created_at": "2018-03-07 00:00:00",
                    "updated_at": "2018-03-07 00:00:00",
                    "time": "07:39 PM",
                    "status": "D"
                }
        },
         my2:{
                {
                    "id": 63,
                    "cuid": 21,
                    "name": "my2",
                    "created_at": "2018-03-07 00:00:00",
                    "updated_at": "2018-03-07 00:00:00",
                    "time": "07:39 PM",
                    "status": "D"
                }
                {
                    "id": 64,
                    "cuid": 21,
                    "name": "my2",
                    "created_at": "2018-03-02 00:00:00",
                    "updated_at": "2018-03-05 00:00:00",
                    "time": "07:01 PM",
                    "status": "D"
                }
        }
    ],
    "message": "User Reportsssss successfully."
}

如果同一用户位于单个数组下，如何实现此目的

Answer 1

执行此操作的理想方法是使用收集管道。你原来的控制器方法将变成以下；

public function index(){
    $reports = Report::all();
    return $this->sendResponse($reports->groupBy('name')->toArray(), 'User Reports successfully.');
}

groupBy

方法会将集合结果拆分为其他集合，并按提供的列进行分组。因为

toArray()

方法会级联，所以你会得到一个不错的数组。

Answer 2

您需要循环遍历结果并根据您的要求进行修改。我已经测试了以下代码，其工作正常。尝试使用它。

$reports = $reports->toArray();
$finalArray = [];

foreach($reports as $key=>$value) {
    $name = $value['name'];
    $finalArray[$name][] = $value;
}

return $this->sendResponse($finalArray, 'User Reports successfully.');

谢谢。
