PayPal provide this code, but something is missing.

 

I understasnd cUrl (I think) but can't see what I need.

 

Half way through the code there is something |I need to implement. What is this?

 

// Post back to PayPal 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); 

// Process validation from PayPal 
// TODO: This sample does not test the HTTP response code. All 
// HTTP response codes must be handles or you should use an HTTP 
// library, such as cUrl 

if (!$fp) { // HTTP ERROR 
} else { 
// NO HTTP ERROR 
fputs ($fp, $header . $req); 
while (!feof($fp)) { 
$res = fgets ($fp, 1024); 
if (strcmp ($res, "VERIFIED") == 0) {
