Papan mesej pembangunan PHP menunjukkan kod lengkap
Kami telah menulis halaman HTML, paging, dan kod paparan lebih awal Sekarang kami perlu menyepadukan mereka ke dalam satu halaman, untuk memenuhi hasrat asal kami adalah seperti berikut
Kod lengkap
<?php
session_start();
header("content-type:text/html;charset=utf-8");
$page=isset($_GET['page']) ?$_GET['page'] :1 ;//接收页码
$page=!empty($page) ? $page :1;
$conn=mysqli_connect("localhost","root","root","Ressage");
mysqli_set_charset($conn,'utf8'); //设定字符集
$table_name="ressage_user";//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 ressage_user order by id desc limit $start ,$perpage";
$result=mysqli_query($conn,$sql);
?>

</html>Dengan kod di atas, anda hanya perlu menyiarkan mesej pada halaman html, dan mesej akan dipaparkan pada halaman yang sama apabila kandungan terisi halaman, kesan paging akan dicapai
Mari kita lihat pada paparan halaman di sebelah kanan terdapat pautan padam di belakang setiap mesej Dalam bab seterusnya, kita akan membuat fungsi padam
