## This page mainly transfers data from our "tiopic" table, and then creates a paging. The code is as follows

<?php
session_start();
header("Content-type:text/html;charset=utf-8");    //设置编码
$page=isset($_GET['page']) ?$_GET['page'] :1 ;//接收页码
$page=!empty($page) ? $page :1;
$F=$_GET['F'];
// 创建连接
$conn = mysqli_connect("localhost", "root", "root", "mybbs");
mysqli_set_charset($conn,'utf8'); //设定字符集
$table_name="tiopic";//查取表名设置
$perpage=5;//每页显示的数据个数
//最大页数和总记录数
$total_sql="select count(*) from $table_name";
$total_result =mysqli_query($conn,$total_sql);
$total_row=mysqli_fetch_row($total_result);
$total = $total_row[0];//获取最大页码数
$total_page = ceil($total/$perpage);//向上整数
//临界点
$page=$page>$total_page ? $total_page:$page;//当下一页数大于最大页数时的情况
//分页设置初始化
$start=($page-1)*$perpage;
$sql="select * from tiopic order by id desc limit $start ,$perpage";
$que=mysqli_query($conn,$sql);
$sum=mysqli_num_rows($que);
?>

In order to make the page beautiful, we have made CSS styles and layouts

We are now' tiopic 'There is no data in the table, so it will display 'There are no posts in this section...'

We have made a link to publish new posts, and now we will make a page to add posts

Next Section

new file

session_start();
header("Content-type:text/html;charset=utf-8"); //设置编码
$page=isset($_GET['page']) ?$_GET['page'] :1 ;//接收页码
