php - PayPal IPN 无效进程

Question

我使用 Oscommerce v2.3.3.4 并使用 PayPal Website Payments Standard 模块设置了一年多。它工作正常，直到上个月我收到了很多标题相同的电子邮件:PayPal IPN Invalid Process mentioned the standard_ipn.php failing。下面是代码:

我已经通过 IPN 模拟器进行了测试，但没有发现任何错误，但仍然收到错误邮件。任何人请帮助。

寻找线

if ( ($res == 'VERIFIED') || ($res == 'INVALID') ) {
  $result = $res;

  break;           
}

并将其替换为

if (strstr($res,'VERIFIED')) {
  $result = 'VERIFIED';

   break;
 }
