重新排列数组索引Eloquent Laravel

标签: php arrays json laravel unset

从laravel eloquent

数组中删除一个元素后出错

物业有房间

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

转换为json,rooms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":""}}}

我在laravel文档中找到了解决方案。

修改数组后,你必须从laravel集合中调用一个方法来命名values()来排列数组索引,例如:

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

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Array,请将assoc标志设置为 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);
