Question

有人可以告訴我這段代碼有什麼問題。

我正在嘗試與支付與HTML表單的貝寶整合。我已經指定了notify_url，支付去所有的權利，但我不能夠在此塊進入if (strcmp($res, "VERIFIED") == 0){}

// Response from Paypl 
// read the post from PayPal system and add 'cmd' 
$req = 'cmd=_notify-validate'; 
foreach ($_POST as $key => $value) { 
    $value = urlencode(stripslashes($value)); 
    $value = preg_replace('/(.*[^%^0^D])(%0A)(.*)/i', '${1}%0D%0A${3}', $value); // IPN fix 
    $req .= "&$key=$value"; 
} 

// assign posted variables to local variables 
$data['item_name'] = $_POST['item_name']; 

// 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.sandbox.paypal.com', 443, $errno, $errstr, 30); 

if (!$fp) { 
    // HTTP ERROR 
    echo 'HTTP ERROR'; 
} else { 

    file_put_contents('test1.txt', 'test'); 
    fputs($fp, $header . $req); 
    while (!feof($fp)) { 
     $res = fgets($fp, 1024); 
     if (strcmp($res, "VERIFIED") == 0) { 
      echo 'SUCCESS'; 
     } else if (strcmp($res, "INVALID") == 0) {     
      echo 'INVALID'; 
     } 
    } 
    fclose($fp); 
}

使用捲曲方法到後回，而不是fsock數據這裏是鏈接：https://developer.paypal.com/webapps/developer/docs/classic/ipn/ht_ipn/或我的建議是使用AngellaEye庫這是更有效和有用的貝寶整合在這裏是鏈接：http://www.angelleye.com/how-to-integrate-paypal-with-php-class-library/ 從這個鏈接下載並去throgh它。
