重新排列的数组索引锋Laravel

Question

我有一个错误之后从laravel口才

的属性的数组中删除元件具有房间

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); 
     } 
    } 

当我编码成JSON此，阵列是转换成对象不是数组

转换成JSON后房间字段应该是一个数组不是对象：

{"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":""}}} 

Answer 1

我发现laravel文档中的溶液中。

修改后阵，你必须调用从命名值laravel集合（）的方法安排数组索引，例如：

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

Answer 2

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); 

选项2

要从JSON转换为阵列设置ASSOC标志TRUE：

json_decode('Your json script', true); 

foreach ($property['rooms'] as $key => $room) { 
    if ($room['type'] == 1) { 
     unset($property['rooms'][$key]); 
    } 
} 
$array = array_values($property['rooms']); 
print_r($array);
