Créer un fichier forums.php
Cette page sert principalement à transférer les données de notre table "tiopic"
Considérant que si nous avons beaucoup de données, l'affichage de la page ne sera pas complet, nous avons donc fait une pagination
en utilisant notre mise en page table+css, le rendu est le suivant
Le code est le suivant
<?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);
?>
