Php I'；我在尝试获取PayPal IPN订阅Id时遇到了最大的困难

我在尝试获取PayPal IPN订阅Id时遇到了最大的困难。这是我的IPN页面

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




if (!$fp) {
// HTTP ERROR
} else {
fputs ($fp, $header . $req);
while (!feof($fp)) {
$res = fgets ($fp, 1024);
if (strcmp ($res, "VERIFIED") == 0) {
// check the payment_status is Completed
// check that txn_id has not been previously processed
// check that receiver_email is your Primary PayPal email
// check that payment_amount/payment_currency are correct
// process payment
  if("susbcr_signup" == $_POST['txn_type']){

      $_id = $_POST['subscr_id'];



    $websites= "websites";
    $database = "k29803_1";
   mysql_connect("localhost", $username, $password) or die(mysql_error());
   mysql_select_db($database);

  $query = "SELECT * FROM users WHERE username= 'drahoslava' AND password = 'drah0slava'";
  $results = mysql_query($query)or die(mysql_error());
    if(mysql_num_rows($results)==1){
        $add_credits = "UPDATE users SET hash = '$_id'
        WHERE username= 'drahoslava' AND password = 'drah0slava'";
        mysql_query($add_credits) or die(mysql_error());
      echo 'done';


      }

}
else if (strcmp ($res, "INVALID") == 0) {
// log for manual investigation
}
}
fclose ($fp);
}
  }
  ?>

这是我的表格

Mysql表不更新。。有什么问题吗*我在

上有自动返回功能，很抱歉这不是一个真正的答案，但我无法将我的建议正确地纳入评论中

尝试为测试目的设置一个额外的表，该表将为每个事务接收ipn信息的原始转储。然后，您可以查看接收到的内容，以确定为什么不将其插入表中

要存储所有原始数据，您可以这样做：

$IpnSerialized = serialize($_POST);
$RawInsert = "INSERT INTO `IpnRaw` (`IpnDump`) VALUES ('{$IpnSerialized}')";

另外，不要向IPN处理程序脚本添加任何回音或打印。反正没人会看到的

---

您可能需要在测试表中添加一些额外的字段，在那里您可以存储进度标记，以查看脚本在爆炸之前的进展情况。

尝试通过电子邮件发送从paypal返回的ipn数据，并查看是否可以获取数据。若你们能得到数据，那个么问题就出在你们的查询中
