Php stdClass对象、方法是否存在？

我正在使用SOAP与支付平台进行通信，我就快到了，剩下的唯一问题是我似乎无法将服务器的答案转化为操作

我需要检查“付款”方法是否存在 我尝试使用方法\u exists如下

if(property_exists($response, 'payment')){
    echo 'PAYMENT EXISTS';
} else {
    echo 'PAYMENT doesnt exist';
}

但它总是返回不存在的付款，我做了什么错事来检查吗？谢谢

这是$response对象的打印

        [success] => stdClass Object
            (

                [code] => SUCCESS
            )

                                        [amount] => stdClass Object
                                            (
                                                [_] => 1500
                                                [currency] => EUR
                                            )

                                    )

                            )

                    )

            )

    )

)

试试这个：

if (
   property_exists($response, 'statusSuccess')
   && property_exists($response->statusSuccess, 'report')
   && property_exists($response->statusSuccess->report, 'payment')
) {
    echo 'payment method exists';
}

if（property_exists（$response->statusSuccess->report'payment'）{

？property_exists（）需要两个参数，其中一个参数在221行的/vagrant/public/meetup.php中给出，工作正常！非常感谢！if（property_exists（$response->statusSuccess->report'payment'））这也起作用了！：）还是使用较长的版本更好？它更安全，因为如果
