【php+mysql】博客分页制作思路,phpmysql分页思路
1、首先需要初始化设置每页显示的文章数$page_size,mysql数据库中总的文章数$arc_size,页面数$page
2、利用分页公式
(当前页数 - 1 )X 每页条数 , 每页条数($Page- 1) * $PageSize,m=$PageSize意思是从table数据表中,从n出开始,直到n+m出结束的内容查询出来 3、显示数据库的内容 代码如下: $conn = @mysql_connect("localhost","root","liujiang") or die("连接数据库服务器失败!");
//连接ly_php_base数据库
$ok = @mysql_select_db("myblog_base",$conn) or die("未能连接到数据库!");
mysql_query("set names 'utf8'"); //解决想mysql数据库中插入汉字失败的问题,这里注意utf8必须和中的这一致
if($ok){echo "mysql is ok!";}else {echo "mysql is failed!";}
$page=$_GET['page'];//获得当前的页面值
if (!isset($page)){$page=1;} //如果没有值,则赋值1
$page_size=2;//每页显示2条
$arcs_result=mysql_query("select count(*) as total from myblog_article");//输出结果为Resource id #4
$arc_size=mysql_result($arcs_result,0,"total");//文章总数
$pagenum=ceil($arc_size/$page_size);
$offset=($page-1)*$page_size;
$sql=mysql_query("SELECT * FROM myblog_article WHERE 1 order by id asc limit $offset,$page_size");
//desc表示降序排序,意思是从$offset开始,排$page_size次
if($sql){echo "query yes";}else {echo "query no";}
$rs=mysql_fetch_array($sql); //提取数据
while($rs) {
?>
文章标题:
文章类型: 文章简介: 上传时间: 文章作者:[]页
$rs = mysql_fetch_array($sql);
}
For($i=1;$i
$show=($i!=$page)?"$i":"$i";
Echo $show." ";
}
?>
