【问题描述】：
第一次来这里，经过几天的尝试解决问题后，我完全被难住了。这是这个问题的背景......
我有一个 PayPal IPN 侦听器脚本。事实上，我有两个版本，因为第一个没有用，所以我尝试了另一个，但也没有用。我从 PayPal 获得的两个 IPN 监听脚本...
paypal_notifyA.php
从... 开发商。贝宝。 com /docs/classic/ipn/gs_IPN/
脚本停在...
fputs($fp, $header . $req);
<?php require_once("../lib/PHPMailer/PHPMailerAutoload.php"); ?>
<?php
// Paypal IPN
// Send an empty HTTP 200 OK response to acknowledge receipt of the notification
header('HTTP/1.1 200 OK');
// Assign payment notification values to local variables
$invoiceID = $_POST['invoice'];
$paymentStatus = $_POST['payment_status'];
$productID = $_POST['item_number'];
$paymentAmount = $_POST['mc_gross'];
$paymentCurrency = $_POST['mc_currency'];
$txnID = $_POST['txn_id'];
$receiverEmail = $_POST['receiver_email'];
$payerEmail = $_POST['payer_email'];
$response = $_POST['response'];
// Build the required acknowledgement message out of the notification just received
$req = 'cmd=_notify-validate'; // Add 'cmd=_notify-validate' to beginning of the acknowledgement
foreach ($_POST as $key => $value) { // Loop through the notification NV pairs
$value = urlencode(stripslashes($value)); // Encode these values
$req .= "&$key=$value"; // Add the NV pairs to the acknowledgement
}
// Set up the acknowledgement request headers
$header = "POST /cgi-bin/webscr HTTP/1.1\r\n"; // HTTP POST request
$header .= "Content-Type: application/x-www-form-urlencoded\r\n";
$header .= "Content-Length: " . strlen($req) . "\r\n\r\n";
// The PayPal IPN Simulator fails on the line below...
// Open a socket for the acknowledgement request
$fp = fsockopen('tls://www.sandbox.paypal.com', 443, $errno, $errstr, 30); // paypal.com (LIVE) - sandbox.paypal.com (TEST)
// Send the HTTP POST request back to PayPal for validation
fputs($fp, $header . $req);
while (!feof($fp)) { // While not EOF
$res = fgets($fp, 1024); // Get the acknowledgement response
if (strcmp ($res, "VERIFIED") == 0) { // Response contains VERIFIED - process notification
$testStage = "Got past Verified!";
require_once("../emails/ipn_test.php");
// DO MY OWN VERIFIED STUFF HERE
// ***** INVALID RESPONSE *****
} else if (strcmp ($res, "INVALID") == 0) { // Response contains INVALID - reject notification
// DO MY OWN INVALID STUFF HERE
}
}
fclose($fp); // Close the file
?>
paypal_notifyB.php
从... github。 com /paypal/ipn-code-samples/blob/master/paypal_ipn.php
脚本停在...
$res = curl_exec($ch);
并在错误日志中报告以下内容...

当我在 PayPal IPN 模拟器中尝试这两个脚本时，都报告...
IPN 已发送，握手已验证。
但是，这两个脚本都不会与 PayPal 进行通信，并且从未达到“如果已验证”条件。因此，在此条件之后还没有后端代码是无关紧要的 - 只是试图让侦听器暂时工作！
我已经和我的网络主机商谈过了，他们说他们禁用了 SSLv3，希望是导致问题的原因。这没有任何区别，两个脚本在它们与 PayPal 通信时继续失败。我的主人声称这不是“他们”的错，而是 PayPal 的问题。尽管我的主机指向相关 SO 线程的方向（我无法发布，因为没有声誉）。

我希望有人能帮我解决这个问题，或者至少确认是“我的”脚本有问题还是服务器有问题，因为我无处可去！
附：我对 PHP 很陌生。
