如何使用Laravel Collection将对象数组转换为嵌套对象

I'm working on data assembling in a Laravel project. The data I could get from sql query is like this

[
  {
    "id": 1,
    "name": "John"
  },
  {
    "id": 2,
    "name": "Ben"
  }
]

I want to convert it to something like this,

{
  "1":{
    "name": "John"
  },
  "2":{
    "name": "Ben"
  }
}

Anyway elegant way to do it?

Use the keyBy collection method
