Hi
I have an website. In this site client can pay for one Item via paypal. I made a paypam Ipn script. But its not working. can anybody help me.
part of My code is

<?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) {

// PAYMENT VALIDATED & VERIFIED!
$item_number=$_POST['item_number1'];
$payment_gross=$_POST['payment_gross'];

is there any problem with last two line of $item_number and $payment_gross ? is '$fp = fsockopen ('ssl://www.paypal.com', 443, $errno, $errstr, 30);' correct?
