第36例：

使用分支语句加载不同网页主体

     $shop_id=$_GET['id'];
     switch($shop_id)
        {
            case "shop1"://如果ID为shop1
                 require("shop1.php");
                 break;
            case "shop2":
                 require("shop2.php");
                 break;
            case "shop3":
                 require("shop3.php");
                 break;
            default://默认的选择
                 require("shop1.php");

        }
