我有一个paypal ipn监听器ipn.php，它链接到一个数据库，用通知信息更新通知表，然后通过电子邮件向付款人发送一个密钥。
这是ipn.php

问题是，当我通过沙盒发送时，它会更新数据库并通过电子邮件发送密钥，但当我尝试实时使用代码时，它什么都没做。。。
我不知道问题出在哪里。
有错误吗？已检查IPN历史日志？如果进行API呼叫，请确保使用LIVE凭据，如果仍然有问题，请向我提供帐号或电子邮件地址，或将票转到paypal.com/mts
我已经设法修复了它，问题是我读取响应的方式，我现在使用；
if (!$fp) {
error_log("could not open socket");
} else {
fputs ($fp, $header . $req);
while (!feof($fp)) {
$res = fgets ($fp, 1024);
if (strcmp ($res, "VERIFIED") == 0){
break;
}
}
}
