우리는 이 태그에 콘텐츠를 추가한 적이 없습니다. 여기에 메시지가 표시됩니다.
다음 코드를 살펴보겠습니다
<div id="right">
~ ~ ~ ~ TR & gt
& ltd colorpan = "4" id = "td" & gt;
& lt; a href = "" "& gt; 홈 & lt;/a & gt;
& lt; a href =" "" "" "" /a>
~
< ;/table>
</div>
테이블을 사용하여 이제 표시 내용을 작성하겠습니다
파일 헤드에 php 태그를 추가하세요
코드는 다음과 같습니다.
<?php
session_start();
require_once('conn.php');//链接数据库
//分页
$page=isset($_GET['page']) ?$_GET['page'] :1 ;//接收页码
$page=!empty($page) ? $page :1;
