假设我有一个这样的集合:
$collection = [
App\User {name: 'Bob', age: 20},
App\User {name: 'Joe', age: 22},
App\User {name: 'Lisa', age: 20}
]
我像$collection->groupBy('age'). 我得到这个结果:
[
"20" => [
App\User {name: 'Bob', age: 20},
App\User {name: 'Lisa', age: 20},
],
"21" => [
App\User {name: 'Joe', age: 22}
]
]
我想删除关联键并只使用索引数组,如下所示:
[
[
App\User {name: 'Bob', age: 20},
App\User {name: 'Lisa', age: 20},
],
[
App\User {name: 'Joe', age: 22]
]
]
这可能与 Laravel 收集方法有关吗?在此先感谢您的指点!
