PHP开发 小型论坛教程之论坛详情
从我们的首页点击进去进去一个论坛，可以看到这个论坛里面所有发布的帖子
本页面主要是从我们的 “tiopic”表中调数据，然后再做个分页，代码如下
<?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);
?>

</html>为了页面美观，我们做了CSS样式和布局
我们现在‘tiopic ’表中没有数据，所以会显示‘本版块没有帖子.....’
我们做了发布新帖的链接，下面我们做添加帖子的页面
<?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);
