php - stdClass 类的对象无法转换为字符串 - 找不到解决方案

Question

我有以下代码:

if ($difference)
{
    $.post("recover_functions/upload_photos.php",
           {upload:$difference},
           function(response)
           {
               alert($difference);
               if (response.status)
                   alert("Successfully uploaded photos");
               else
                   alert(response);
            });
}

警报将显示:

{"difference":"[{\"aid\":\"100000543443572_1073741825\",\"backdated_time\":null,\"caption\":\"\",\"link\":\"http:\\\/\\\/www.facebook.com\\\/photo.php?fbid=614604095234366&set=a.614604001901042.1073741825.100000543443572&type=1\",\"pid\":\"100000543443572_2384218\",\"place_id\":null}]"}

然后我收到这样的 `POST 请求:

$string_diff = $_POST['upload'];
$array_diff  = json_decode($string_diff);

echo $array_diff;

不是响应是类 stdClass 的对象无法转换为字符串。请帮忙，我有一个截止日期(1 小时)，但我无法正常工作。

与数组一样，您不能回显 stdClass 对象。您可以像这样 var_dump($array_diff) 并回显特定属性:

echo $array_diff->my_property;
