重新排列数组索引 —— Eloquent Laravel

8

我在laravel eloquent的数组中删除元素后出现了错误

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);
        }
    }

当我将这个编码为json时,数组被转换成���对象而不是数组。 unset之前

将其转换为JSON格式时,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":""}}}

请问您能否发布$property->rooms的原始PHP对象? - Ghassan Elias

我在Laravel文档中找到了解决方案。

修改数组后,您需要调用名为values()的Laravel集合方法来排列数组索引。例如:

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

你在文档中找到这个在哪里了吗?@Miguel - arvil

Option 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

要将JSON转换为数组,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);
