以下代码是PHP分页案例，测试通过，主要是PHP+mysql实现分页，代码来处百度空间，有兴趣看的话可以了解一下PHP是如何分页的？
<?php
$link = mysql_connect("localhost","root", "2855") //连接数据库
or die("连接不上服务器：".mysql_error());
mysql_select_db("aming");
$ittype=$_GET['ittype'];
if($ittype==""){
echo "请输入查询条件";
exit;
}
$PageSize = 4;//每页显示记录数
$StartRow = 0; //开始显示记录的编号
//获取需要显示的页数，由用户提交
if(empty($_GET['PageNo'])){ //如果为空，则表示第1页
if($StartRow == 0){
$PageNo = $StartRow + 1; //设定为1
}
}else{
$PageNo = $_GET['PageNo']; //获得用户提交的页数
$StartRow = ($PageNo-1) * $PageSize; //获得开始显示的记录编号 $StartRow = ($PageNo - 1) * $PageSize;
} //因为显示页码的数量是动态变化的
//假如总共有一百页，则不可能同时显示100个链接
//而是根据当前的页数显示一定数量的页面链接
//设置显示页码的初始值
if($PageNo % $PageSize == 0){
$CounterStart = $PageNo - ($PageSize - 1);
}else{
$CounterStart = $PageNo - ($PageNo % $PageSize) + 1;
} //显示页码的最大值
$CounterEnd = $CounterStart + ($PageSize - 1);
?> <html>
<head>
<title>分页显示记录</title>
<link rel="stylesheet" href="include/style.css" type="text/css"></head>
<?php
/*$itname=$_POST['itname'];
if($itname ==""){
echo "请输入查询条件";
exit;
}*/ if($ittype)
$TRecord = mysql_query("select *from pc_it where ittype=$ittype");
$result = mysql_query("select *from pc_it where ittype=$ittype ORDER BY id DESC LIMIT $StartRow,$PageSize"); //获取总记录数
$RecordCount = mysql_num_rows($TRecord); //获取总页数
$MaxPage = $RecordCount % $PageSize;
if($RecordCount % $PageSize == 0){
$MaxPage = $RecordCount / $PageSize;
}else{
$MaxPage = ceil($RecordCount / $PageSize);
