无JS,完全php面向过程数据分页实现代码

<?php
//登陆页面设置的session,当session中存在name时
//session_start();
//$name = $_session['name'];
//if (empty($name)){
// header("location: error.php");
// exit();
//}
//面向过程, 数据分页显示
if(false!=($mysql = mysql_connect('本地mysql', 'mysql用户名', 'mysql密码'))){
mysql_query('set names utf8',$mysql); //设置数据库中的编码
mysql_select_db("数据库database",$mysql);
}else{
die("连接失败");
}


$pagesize = 10; //页面显示条数
$rowcount = 0; //数据总条数,从数据库获得

$sqlcount = 'select count(id) from employee';
$res1 = mysql_query($sqlcount,$mysql);

//取出数据条数
if(false!=($row=mysql_fetch_row($res1))){
$rowcount = $row[0];
}

//总页数,通过计算得到
$pagecount = 0;
$pagecount = ceil($rowcount/$pagesize);

//获取当前页
if(!isset($_get['pagenow'])){ // 当 get/post都为空的时候赋默认值1
$pagenow = 1; //当前页数
}elseif(false!=is_numeric($_get['pagenow']) && $_get['pagenow']<=$pagecount){
$pagenow = $_get['pagenow'];
}else{
header("location: ../error/error.php");
exit();
}
//打印分页数据
echo "<div style='margin-left:300px;margin-top:1px;'>";
