Cross Verification for Paypal


Hi All, This is the code for cross verification of request from paypal, after transaction {php} $req = 'cmd=_notify-validate'; foreach ($_POST as $key => $value) { $value = urlencode(stripslashes($value)); $req .= "&$key=$value"; } // post back to PayPal system to validate $header .= "POST /cgi-bin/webscr HTTP/1.0rn"; $header .= "Content-Type: application/x-www-form-urlencodedrn"; $header .= "Content-Length: " . strlen($req) . "rnrn"; $fp = fsockopen ('ssl://www.paypal.com', 443, $errno, $errstr, 30); // assign posted variables to local variables $item_name = $_POST['item_name']; $item_number = $_POST['item_number']; $payment_status = $_POST['payment_status']; $payment_amount = $_POST['mc_gross']; $payment_currency = $_POST['mc_currency']; $txn_id = $_POST['txn_id']; $receiver_email = $_POST['receiver_email']; $payer_email = $_POST['payer_email']; if (!$fp) { // HTTP ERROR } else { fputs ($fp, $header . $req); while (!feof($fp)) { $res = fgets ($fp, 1024); if (strcmp ($res, "VERIFIED") == 0) { // process payment } else if (strcmp ($res, "INVALID") == 0) { // log for manual investigation } } fclose ($fp); } {php} Thanks
