我在代码中存储多个ID时遇到问题。我需要将id保存在单个变量（数组）中，因为我将在cart.php中调用它来显示添加到购物车的项目。这是我的代码。
<!--This is the android.php where you can browse the items to be added to the cart -->
<?php
include('php/userloginprocess.php'); // Includes Login Script
if($_SESSION['login'] == FALSE){
header("location: login.php");
}
if($_SESSION['login'] == TRUE)
?>

答案 0 :(得分：0)
我设法通过使用不同的方法检索id并将其存储在多维数组中来回答我自己的问题。
