Create forums.php file

This page is mainly to transfer data from our "tiopic" table

Considering that if we have a lot of data, the page display will not be complete, so we did paging

Using our table+css layout, the rendering is as follows

##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);
?>
