我正在运行PayPal订阅，我试图根据收到的响应来启动数据库写入。直到昨天，代码工作正常。但奇怪的是，今天，代码在收到付款后停止发送电子邮件。我不确定这是否是PayPal方面或我的问题。我不认为它与我的代码有关，因为我从代码中剥离了很多代码，而且我正在使用基本版本的IPN进行支付跟踪，但即使这样，它也不会使数据库插入或触发电子邮件。PayPal IPN订阅 - 部分作品
我也搜索了可能的解决方案&甚至实施了我发现的接近我的答案。但不幸的是，他们没有工作。因此，这里是我的IPN代码：
<?php
// read the post from PayPal system and add 'cmd'
$req = 'cmd=_notify-validate';
foreach ($_POST as $key => $value) {
$value = urlencode(stripslashes($value));
$req .= "&$key=$value";
}
// post back to PayPal system to validate
$header = "POST /cgi-bin/webscr HTTP/1.0\r\n";
$header .= "Content-Type: application/x-www-form-urlencoded\r\n";
$header .= "Content-Length: " . strlen($req) . "\r\n\r\n";

我已经注意到，直到下面的行，代码工作正常：mail($notify_email, "IPN Triggered 1", "IPN Triggered 1");我收到这封电子邮件的主题为IPN触发1。所以直到这条线，它的工作很好。
一旦进入while循环，它就会触发邮件而不是。 if (strcmp ($res, "VERIFIED") == 0)中有邮件功能，但没有被触发。这是昨天工作，但今天它不是！没有任何在while循环内的邮件功能被触发。
可以做些什么来解决这个问题，以便我可以执行这两个操作，即写入数据库和发送邮件？
编辑1：
好吧，我剥即插入到数据库&它仍然进行同样的操作代码。我真的觉得PayPal Sandbox没有发送回应。任何人都可以请确认吗？
，我修改了代码的另一半，现在看起来是这样的：
if (!$fp)
{
// HTTP ERROR
}
else
{
mail($notify_email, "IPN Triggered 1", "IPN Triggered 1");
fputs ($fp, $header . $req);
while (!feof($fp))
{
//Already used this
//$res = fgets ($fp, 1024);
//Using this to see if it sends response
$res = stream_get_contents($fp, 1024);
if (strcmp ($res, "VERIFIED") == 0)
{
mail($notify_email, "VERIFIED 1", "VERIFIED 1");
}
// if the IPN POST was 'INVALID'...do this
else if (strcmp ($res, "INVALID") == 0)
{
// log for manual investigation
mail($notify_email, "INVALID IPN", "$res\n $req");
}
}
fclose ($fp);
}
