您好，我對PHP和Bootstrap很新。我開發了一個使用php和Bootstrap的電子商務網站。這個應用程序只是添加和刪除產品來回購物車，並計算所有產品的總價格，如果用戶有優惠券，他可以申請'off30' ，他將得到總價格30％的折扣。我正在經歷錯誤，因爲解析錯誤：語法錯誤，指向下面代碼最後一行的文件意外結束。請幫我解決這個錯誤。與電子商務網站相關的PHP和自舉代碼

case "add":
if(!empty($_POST["quantity"])) {
$productByCode = mysqli_query($conn,"SELECT * FROM tblproduct WHERE code='" . $_GET["code"] . "'");
$products = mysqli_fetch_array($productByCode);
$itemArray = array($products["code"]=>array('name'=>$products["name"], 'code'=>$products["code"], 'quantity'=>$_POST["quantity"], 'price'=>$products["price"]));
