从 laravel eloquent 数组中删除一个元素后出现错误
一个属性有房间
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，数组被转换为对象而不是数组

转换为 json rooms 字段应该是数组而不是对象:
{"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":""}}}
最佳答案
我在 laravel 文档中找到了解决方案。
修改数组后，你必须从 laravel 集合中调用一个名为 values() 的方法来排列数组索引，示例:
unset($property->rooms[$key]);
$property->rooms->values();
关于php - 重新排列数组索引 Eloquent Laravel，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/27309747/
