This section shows the complete functional module of new book management in the book backend management system. First, we
need to introduce the database file config.php file and the ly_check.php file that determines whether the administrator is logged in
Call the css.css style in the HTML page
The new book management function page is named list.php
<?php
include("config.php");
require_once('ly_check.php');

//mysql_num_rows() 返回结果集中行的数目。此命令仅对 SELECT 语句有效。

$pagecount = (int)$pagecount;
$pageno = $_GET["pageno"]; //获取当前页
