stdClass对象，方法存在吗？

Question

我正在与SOAP进行通信以与支付平台进行通信，我快到了，剩下的唯一问题是我似乎无法将服务器的答案转换为操作

我需要检查“付款”方法是否存在

我已经尝试使用method_exists如下

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

但是它总是不存在还款的问题，我在做错什么来检查吗？ 谢谢！

这是$ response对象的print_r

尝试这个：

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