PayPal IPN配置

Question

我一直试图为一个网站配置IPN我正试图建立。长话短说，我希望这是对我的数据库条目的控制，其他API在其他地方下订单。

我就是不能让它工作。检查PayPal网站上的IPN历史看起来像是向URL发送ok（我在按钮中指定了，而不是通过PayPal），但绝对没有发生任何事情。从我的脚本，我希望一封电子邮件陈述失败或成功。我还尝试在我的listener.php中设置一个会话变量，我在返回url上检查这个变量（尽管我认为由于IPN和返回页面不一定连续运行，所以没有设置这个变量）...

<?php
// listener.php
$_SESSION['listener'] = 'reached';


// read the post from PayPal
$req = 'cmd=_notify-validate';
foreach ($_POST as $key => $value) {
   $value = urlencode(stripslashes($value));
   $req .= "&$key=$value";
}

// post back to PayPal
$header = "POST /cgi-bin/webscr HTTP/1.1\r\n";
$header .= "Content-Type: application/x-www-form-urlencoded\r\n";
$header .= "Content-Length: " . strlen($req) . "\r\n\r\n";
$header .= "Conection: Close";

$fp = fsockopen ('ssl://www.sandbox.paypal.com', 443, $errno, $errstr, 30);


if (!$fp) {
   // HTTP ERROR
}
else {
   fputs ($fp, $header . $req);

   $res = stream_get_contents($fp, 1024);
   if (strcmp ($res, "VERIFIED") == 0) {

      $to      = '[e-mail]';
      $subject = 'IPN VERIFIED';
      $message = $req;
      $headers = 'From:[e-mail]' . "\r\n";

      mail($to, $subject, $message, $headers); 
   }

   else if (strcmp ($res, "INVALID") == 0) {

      $to      = '[e-mail]';
      $subject = 'IPN INVALID';
      $message = $req;
      $headers = 'From:[e-mail]' . "\r\n";

      mail($to, $subject, $message, $headers);

   }

   fclose ($fp);
}
?>

我通过向自己发送电子邮件检查了$res的值，尽管我期望的是“验证”或“无效”，但实际上是这样的：
