贝宝IPN可在沙盒中工作，但不能实时运行

Question

I have obtained and adapted the following code from here http://www.sanwebe.com/2012/07/paypal-instant-payment-notification-ipn/comment-page-1#comment-6871

<?php
include 'dbdata.php';
//Change these with your information
$paypalmode = 'sandbox'; //Sandbox for testing or empty ''
$paypalmode = '';
if($_POST)
{
    if($paypalmode=='sandbox')
    {
        $paypalmode     =   '.sandbox';
    }
    $req = 'cmd=' . urlencode('_notify-validate');
    foreach ($_POST as $key => $value) {
        $value = urlencode(stripslashes($value));
        $req .= "&$key=$value";
    }
    $ch = curl_init();
    //curl_setopt($ch, CURLOPT_URL, 'https://www'.$paypalmode.'.paypal.com/cgi-bin/webscr');
    curl_setopt($ch, CURLOPT_URL, 'https://www.paypal.com/cgi-bin/webscr');
    curl_setopt($ch, CURLOPT_HEADER, 0);
    curl_setopt($ch, CURLOPT_POST, 1);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER,1);
    curl_setopt($ch, CURLOPT_POSTFIELDS, $req);
    curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 1);
    curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 2);
    //curl_setopt($ch, CURLOPT_HTTPHEADER, array('Host: www'.$paypalmode.'.sandbox.paypal.com'));
    curl_setopt($ch, CURLOPT_HTTPHEADER, array('Host: www.paypal.com'));
    $res = curl_exec($ch);
    curl_close($ch);

    if (strcmp ($res, "VERIFIED") == 0)
    {
        $transactionID = $_POST['txn_id'];
        $payerEmail = $_POST['payer_email'];
        $paymentStatus = $_POST['payment_status'];
        $firstName = $_POST['first_name'];
        $surname = $_POST['last_name'];
        $payerID = $_POST['payer_id'];
        $addressName = $_POST['address_name'];         
        $addressCountry = $_POST['address_country'];
        $addressCountryCode = $_POST['address_country_code'];
        $addressZip = $_POST['address_zip'];
        $addressState = $_POST['address_state'];
        $addressCity = $_POST['address_city'];
        $addressStreet = $_POST['address_street'];
        $mcGross = $_POST['mc_gross'];
        $mcShipping = $_POST['mc_shipping'];
        $mcCurrency = $_POST['mc_currency'];
        $paymentDate = $_POST['payment_date'];


        $mdate= date('Y-m-d H:i:s',strtotime($paymentDate));
        $otherStuff = json_encode($_POST);

          $query5 = "INSERT INTO paypal (transationID,payerEmail,paymentStatus,firstName,surname,paymentDate,payerID,addressName,addressCountry,addressCountryCode,addressZip, addressState,addressCity,addressStreet,mcGross,mcShipping,mcCurrency,allData) VALUES  ('".$transactionID."','".$payerEmail."','".$paymentStatus."','".$firstName."','".$surname."','".$mdate."','".$payerID."','".$addressName."','".$addressCountry."','".$addressCountryCode."','".$addressZip."','".$addressState."','".$addressCity."','".$addressStreet."','".$mcGross."','".$mcShipping."','".$mcCurrency."','".$otherStuff."')";


     mysql_query($query5); 
  $mail_From    = "xxx@googlemail.com";
  $mail_To      = "xxx@googlemail.com";
  $mail_Subject = "VERIFIED IPN";
  $mail_Body    = $otherStuff;
  //mail($mail_To, $mail_Subject, $mail_Body, $mail_From);

    }

    if (strcmp ($res, "INVALID") == 0)
    {
        $transaction_id = $_POST['txn_id'];
        $payerid = $_POST['payer_id'];
        $firstname = $_POST['first_name'];
        $lastname = $_POST['last_name'];
        $payeremail = $_POST['payer_email'];
        $paymentdate = $_POST['payment_date'];
        $paymentstatus = $_POST['payment_status'];
        $mdate= date('Y-m-d h:i:s',strtotime($paymentdate));
        $otherStuff = json_encode($_POST);

         $query5 = "INSERT INTO paypal (transationID,payerEmail,paymentStatus) VALUES  ('".$transaction_id."','".$payeremail."','".$paymentstatus."')";
     mysql_query($query5); 

    }
}
?>

If I use sandbox mode and the IPN simulator I get the data inserted correctly into the tables. I have now set the clients paypal account's IPN setting to point to my script and turned on IPN but I do not get anything happening.

The web site is using express checkout. The web site is USA based. The php script is hosted on our server (UK).

Paypal is showing sent and if I re-send the IPN's they re-appear as sent. Can anyone see what is wrong here?

• Update. I have used my UK based paypal account and set the IPN notification to the same URL and sent a payment from my wife's paypal account and I got an entry into the database.

Also I do not get my wife's customer details from the IPN but I do from the simulator.

Just replace

foreach ($_POST as $key => $value) {
    $value = urlencode(stripslashes($value));
    $req .= "&$key=$value";
}

with

foreach ($_POST as $key => $value){
    $value = urlencode(stripslashes($value));
    $value = preg_replace('/(.*[^%^0^D])(%0A)(.*)/i','${1}%0D%0A${3}',$value);// IPN fix
    $req .= "&$key=$value";         
}
