Question

是否可以在列上使用sum（）将laravel集合分组？该集合看起来像这样：

    [
    {id: 1, name: A, quantity: 1, price: 20, options:[{id:10,name:AC}{id:13,name:AB}]},
    {id: 1, name: A, quantity: 5, price: 15, options:[{id:20,name:AV},{id:30,name:AZ}]},
    {id: 1, name: A, quantity: 10, price: 15, options:[{id:20,name:AV},{id:30,name:AZ}]},
    {id: 1, name: A, quantity: 2, price: 10, options:[]},
    {id: 1, name: A, quantity: 4, price: 10, options:[]}
    ]

第2行和第3行相同，我需要对数量进行求和。

第4行和第5行相同，我需要求和（）数量。

结果应该是这样的：

  [
    {id: 1, name: A, quantity: 1, price: 20, options:[{id:10,name:AC}{id:13,name:AB}]},
    {id: 1, name: A, quantity: 15, price: 15, options:[{id:20,name:AV},{id:30,name:AZ}]},
    {id: 1, name: A, quantity: 6, price: 10, options:[]},
    ]
