从雄辩的laravel数组中删除元素后出现错误

I have an error after delete an element from an array of laravel eloquent

酒店有房间

foreach ($property->rooms as $key => $room) { if ($room->type == 1 and $type ==1 and $room->price < $price->min or $room->price > $price->max) { print_r($property->rooms); unset($property->rooms[$key]); //$array = array_values($property->rooms); doesn't work print_r($property->rooms); } }

当我将其编码为json时，数组将转换为对象而不是数组

When i encode this into a json, the array is convert into an object not an array

未设置

)

转换为json后，rooms字段应为数组而不是对象:

{"other_parameters": "something","rooms":{"1":{"id":2,"properties_id":4,"price":350000,"is_available":1,"created_at":"-0001-11-30 00:00:00","updated_at":"2014-10-21 18:13:15","type":1,"description":null},"2":{"id":3,"properties_id":4,"price":250000,"is_available":1,"created_at":"-0001-11-30 00:00:00","updated_at":"-0001-11-30 00:00:00","type":1,"description":""}}}

推荐答案

我在laravel文档中找到了一个解决方案.

I have found a solution in the laravel documentation.

修改数组之后，您必须从laravel集合中调用一个名为values()的方法来排列数组索引，例如:

after modifying the array, you have to call a method from laravel collection named values() that arrange the array indexes, example:

unset($property->rooms[$key]); $property->rooms->values();
