从laravel eloquent数组中删除一个元素后出错
酒店设有客房
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

转换为json,房间字段应该是一个数组而不是一个对象：
{"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":""}}}
解决方法:
我在laravel文档中找到了一个解决方案.
在修改数组之后,你必须从laravel集合中调用一个名为values()的方法来安排数组索引,例如：
unset($property->rooms[$key]);
$property->rooms->values();
