<?php

$header  = "POST /cgi-bin/webscr HTTP/1.0\r\n";
$header .= "Content-Type: application/x-www-form-urlencoded\r\n";

  	//If testing on Sandbox use:
	//$fp = fsockopen ('ssl://www.sandbox.paypal.com', 443, $errno, $errstr, 30);
 
$fp = fsockopen ('www.paypal.com', 80, $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
 
 
// echo the response
echo "The response from IPN was: <b>" .$res ."</b><br><br>";
 
//loop through the $_POST array and print all vars to the screen.
 
foreach($_POST as $key => $value){
 
        echo $key." = ". $value."<br>";
 
 
 
}

// log for manual investigation
 
// echo the response
echo "The response from IPN was: <b>" .$res ."</b>";
 
  }
 
}
fclose ($fp);
}
?>

Merci d'avance pour votre aide.
