我正在处理条纹付款，我正在尝试将金额设置为变量。我看到有很多关于这方面的问题，但我找不到他的答案。
在页面顶部，我查询我的数据库中的数字并进行一些基本的数学运算来设置数量。我回应成本只是为了确保它正常运行。这是
的代码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;
然后我尝试将费用分配给某个if语句和异常中的另一个变量金额，并尝试回显金额，但我一无所获。
// Set the order amount somehow:
$amount = $cost; // in cents
echo $amount;
$email = "info@intelycare.com";
$description = "Jane Doe"; //customer
当我echo $amount没有任何显示时。这里是页面的完整代码。我可以帮忙解决这个问题。

我联系了Stripe，他们给了我几个建议，这里有一个问题的解决方案，希望它能让其他人受益。我可以为条带付款传递可变金额。下面是我的charge.php文件，我还没有处理错误，但我稍后会包含它。
<?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;
?>
