如何在PHP中访问stdClass的成员 [英] How to access a member of an stdClass in PHP

问题描述

我有一个解码的JSON对象，由于出现错误，我无法访问该元素.

I have a JSON object that I decoded, and I can't access the element because it throws an error.

stdClass Object
(
    [error] => InvalidRegistration
)

echo $device_response->error; // gives an error

我该如何访问属性?

下面是整个响应数组:

stdClass Object
(
    [multicast_id] => 5.3301797222004E+18
    [success] => 1
    [failure] => 3
    [canonical_ids] => 0
    [results] => Array
        (
            [0] => stdClass Object
                (
                    [message_id] => 0:1388910534147789%25796c83f9fd7ecd
                )

            [1] => stdClass Object
                (
                    [error] => InvalidRegistration
                )

            [2] => stdClass Object
                (
                    [error] => InvalidRegistration
                )

            [3] => stdClass Object
                (
                    [error] => InvalidRegistration
                )

        )

)

下面是我的访问方式:

foreach ($responseBody->results as $device_response) {

        echo $device_response->error;

    }

推荐答案

$obj = new stdClass();
$obj->foo = "var";
echo $obj->foo;
