laravel-多条件查询并指定key输出

$room =  DB::table('room')
    ->where(function($query) use($contList){
        foreach ($contList as $k=>$v){
            //拼接查询条件
            $query->orwhere(function ($query) use($v) {
                $query->where('id', '=', $v['room_id'])->where('hotel_id', '=', $v['hotel_id']);
            });
        }
    })
    ->select(['id','hotel_id','room_number'])
    ->get()->keyBy('id')
    ->toArray();

以上代码解析sql语句如下

"select `id`, `hotel_id`, `room_number` from `mm_room` where ((`id` = ? and `hotel_id` = ?) or (`id` = ? and `hotel_id` = ?) or (`id` = ? and `hotel_id` = ?))"

注：keyBY() 意为：以id为键值输出  必须写到get()后面 不然会报错
