Php 合并共享相同id的数组,php,mysql,laravel,Php,Mysql,Laravel,目前我有这样的JSON： [ { "user_id": 6, "room_id": 2, "date_from": "2019-09-15 00:00:00", "date_to": "2020-09-01 00:00:00", "created_at": null, "updated_at": null, "users": [ { "id": 6, "name": "Makenna",

按功能实现：

$rooms = OccupiedRoom::with([
            'users' => function ($query) {
                $query->select(['id', 'name', 'surname', 'email', 'university_id']);
            },
            'room.dorm' => function ($query) {
                $query->select('dorms.id', 'dorms.name', 'dorms.university_id', 'dorms.photo');
            },
            'room.dorm.university' => function ($query) {
                $query->select('universities.id', 'universities.name', 'universities.city');
            },
        ])->get();

我需要的是，如果阵列共享相同的

房间id

，它将与多个

用户合并为一个阵列，如下所示：
