    )

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":""}}}

选项1

$array = array();
foreach ($property->rooms as $key => $room) {
    if ($room->type == 1) {
        unset($property->rooms->{$key}); <<-- pay attention to this
    } else {
        $array[] = get_object_vars($room); // sort the passed row into new array
    }
}
print_r($array);

我在laravel文档中找到了一个解决方案

修改数组后,必须从laravel集合调用名为values()的方法来排列数组索引,例如:

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

请将$property->rooms的原始php对象发布到文档中,您在哪里找到了它@米格尔
unset($property->rooms[$key]);
$property->rooms->values();
