Php Laravel-通过数据透视表访问、操作和循环

我有两个表，

users

和

like_categories

，它们具有

多对多关系。
pivot表
被称为
like\u category\u user
。将两个用户数据插入
db
后，我的
透视表如下所示：

我想计算每个
用户的
不同类别的
金额
，并将其存储在
对象数组中，如下所示：

[
    {
        "User Id": 1,
        "Like Categories": [
            {
                "Category": "Chinese Restaurant"
                "Amount": 1
            },
            {
                "Category": "Korean Restaurant"
                "Amount": 2
            },
            {
                "Category": "Fast Food Restaurant"
                "Amount": 3
            },
            {
                "Category": "Italian Restaurant"
                "Amount": 1
            },
            {
                "Category": "Steakhouse Restaurant"
                "Amount": 3
            }
        ]
    },
    {
        "User Id": 2,
        "Like Categories": [
            {
                "Category": "Thai Restaurant"
                "Amount": 1
            },
            {
                "Category": "Kebab Shop"
                "Amount": 3
            },
            {
                "Category": "Pizza Place"
                "Amount": 2
            },
            {
                "Category": "Steakhouse"
                "Amount": 1
            }
        }
    }
]

我尝试将数据库中的数据存储到基于上述格式的对象数组中。但是输出不是我想要的。
我的代码：

对象数组
我得到：

[
    {
        "User Id": 1,
        "Like Categories": [
            {
                "Category": "Chinese Restaurant",
                "Amount": 1
            },
            {
                "Category": "Korean Restaurant",
                "Amount": 2
            },
            {
                "Category": "Korean Restaurant",
                "Amount": 2
            },
            {
                "Category": "Fast Food Restaurant",
                "Amount": 3
            },
            {
                "Category": "Fast Food Restaurant",
                "Amount": 3
            },
            {
                "Category": "Fast Food Restaurant",
                "Amount": 3
            },
            {
                "Category": "Italian Restaurant",
                "Amount": 1
            },
            {
                "Category": "Steakhouse",
                "Amount": 3
            },
            {
                "Category": "Steakhouse",
                "Amount": 3
            },
            {
                "Category": "Steakhouse",
                "Amount": 3
            }
        ]
    },
    {
        "User Id": 2,
        "Like Categories": [
            {
                "Category": "Thai Restaurant",
                "Amount": 1
            },
            {
                "Category": "Kebab Shop",
                "Amount": 3
            },
            {
                "Category": "Kebab Shop",
                "Amount": 3
            },
            {
                "Category": "Kebab Shop",
                "Amount": 3
            },
            {
                "Category": "Pizza Place",
                "Amount": 2
            },
            {
                "Category": "Pizza Place",
                "Amount": 2
            },
            {
                "Category": "Steakhouse",
                "Amount": 1
            }
        ]
    }
]

如果您需要相同的输出，只需更换此

$users = User::all();

到

等待输出之间有什么区别？@AntonyMN有一些多余的键。也许是因为我的想法也许我想问的是。。。你得到的和你想要的有什么区别？也就是说，解释一下你真正想做什么，也许有一种更简单的方法，或者是一个laravel函数available@AntonyMN我已经编辑了我的帖子：）
$users = User::all();

$users = User::all()->toArray();
