5.4 book_fns.php文件中的函数calculate_items()
function calculate_items($cart) //计算购物车中的物品总数

获取顾客的详细信息
由以下代码实现：
5.5 checkout.php
<?php
/**
* @author switch
* @copyright 2015
* 向用户显示所有的订单细节。获取商品运送细节
*/
//require_once语句和require语句完全相同,唯一区别是PHP会检查该文件是否已经被包含过,如果是则不会再次包含。
require_once('book_sc_fns.php');
session_start();
do_html_header("Checkout");
if((@$_SESSION['cart']) && (array_count_values($_SESSION['cart'])))
{
display_cart($_SESSION['cart'],false,0);
display_checkout_form();
}
else
{
echo "<p>Thers are no items in your cart</p>";
}
display_button("show_cart.php","continue-shopping","Continue Shopping");
do_html_footer();
?>
5.6 output_fns.php文件中的display_checkout_form()
function display_checkout_form() //输出付款台界面
{
?>
