在页面顶部，我查询数据库中的a数字，并做一些基本的数学运算来设置数量。我重复成本，只是为了确保它正常工作。这是代码

require_once('../stripe/lib/Stripe.php');
        require_once("../auth/config.class.php");
        require_once("../auth/auth.class.php");

        $config = new Config;

        $dbh = new PDO("mysql:host={$config->dbhost};dbname={$config->dbname}", $config->dbuser,     $config->dbpass);
        $auth = new Auth($dbh, $config);

        $id= $_GET['rid'];

        $query = $dbh->prepare("SELECT hours FROM svcrequest WHERE id=? ");
        $query->execute(array($id));    
        $rslt = $query->fetch(PDO::FETCH_ASSOC);
        $cost    = ($rslt[hours] * 27)*100;
        echo $cost;

然后，我尝试将成本分配给某个if语句和异常中的另一个变量金额，并尝试响应金额，但什么也得不到

// Set the order amount somehow:
        $amount  = $cost; //  in cents
        echo $amount;
        $email       = "info@intelycare.com";
        $description = "Jane Doe"; //customer

当我

echo$amount

时，什么也不显示。这里是页面的完整代码。我需要一些帮助

我联系了Stripe，他们给了我一些建议，这里有一个解决问题的方法，希望它能让其他人受益。我可以通过一个可变金额的条纹付款。下面是我的charge.php文件，我还没有处理错误，但我将在以后包含它
<?php
require_once(dirname(__FILE__) . '/config.php');
require_once("../auth/config.class.php");
require_once("../auth/auth.class.php");

$config = new Config;

$dbh = new PDO("mysql:host={$config->dbhost};dbname={$config->dbname}", $config->dbuser,     $config->dbpass);
$auth = new Auth($dbh, $config);

$id= $_GET['rid'];

$query = $dbh->prepare("SELECT hours, cid FROM svcrequest WHERE id=? ");
$query->execute(array($id));    
$rslt = $query->fetch(PDO::FETCH_ASSOC);
$cost    = ($rslt['hours'] * 23)*100;
echo $cost;
$cid = $rslt['cid'];

$query  = $dbh->prepare("SELECT email, fname, lname FROM client JOIN users ON client.uid = users.id WHERE uid =(SELECT uid FROM client WHERE id=?)");
$query->execute(array($cid));
$user =$query->fetch(PDO::FETCH_ASSOC);
$email = ($user['email']);
echo $email;



$token = $_POST['stripeToken'];





$customer = Stripe_Customer::create(array(
'email' => $email,
'card' => $token
));

$charge = Stripe_Charge::create(array(
'customer' => $customer->id,
'amount' => $cost,
'currency' => 'usd'
));

echo '<h3>Charge today:</h3>' . $cost;
?>
