paypall IPN verifica

ciao si certo l'account è di prova...

solo che ho provato mettendo una scrittura a un file per debuggare ma in nessuno dei casi scrive qualcosa su file niente di niente....

adesso ho trovato uno script che usa cUrl e sembra che almeno scriva errore :

$req = 'cmd=_notify-validate';

// Run through the posted array
foreach ($_POST as $key => $value)
{
    // If magic quotes is enabled strip slashes
    if (get_magic_quotes_gpc())
    {
        $_POST[$key] = stripslashes($value);
        $value = stripslashes($value);
    }
    $value = urlencode($value);
    // Add the value to the request parameter
    $req .= "&$key=$value";
}

$url = "http://www.sandbox.paypal.com/cgi-bin/webscr";
$ch = curl_init();    // Starts the curl handler
curl_setopt($ch, CURLOPT_URL,$url); // Sets the paypal address for curl
curl_setopt($ch, CURLOPT_FAILONERROR, 1);
curl_setopt($ch, CURLOPT_RETURNTRANSFER,1); // Returns result to a variable instead of echoing
curl_setopt($ch, CURLOPT_TIMEOUT, 3); // Sets a time limit for curl in seconds (do not set too low)
curl_setopt($ch, CURLOPT_POST, 1); // Set curl to send data using post
curl_setopt($ch, CURLOPT_POSTFIELDS, $req); // Add the request parameters to the post
$result = curl_exec($ch); // run the curl process (and return the result to $result
curl_close($ch);

if (strcmp ($result, "VERIFIED") == 0) // It may seem strange but this function returns 0 if the result matches the string So you MUST check it is 0 and not just do strcmp ($result, "VERIFIED") (the if will fail as it will equate the result as false)
{
    // Do some checks to ensure that the payment has been sent to the correct person
    // Check and ensure currency and amount are correct
    // Check that the transaction has not been processed before
    // Ensure the payment is complete
    $myFile ='../paypall.txt';
$fh = fopen($myFile, 'w') or die("can't open file");
$stringData = "VERIFIED";
fwrite($fh, $stringData);
fclose($fh);
}
else
{
    // Log an invalid request to look into
    $myFile ='../paypall.txt';
$fh = fopen($myFile, 'w') or die("can't open file");
$stringData = "ERROR  =>".$req."";
fwrite($fh, $stringData);
fclose($fh);
} 

con questo codice quanto meno scrive al file.... e mi scriver esattamente "ERROR" come scritto nel codice dell'ultimo else{}



non riesco a capire perchè tanto tribolare.... le api di paypall fanno schifo o sono io che mi perdo in un bicchiere d'acqua?
