如下代碼是PHP分頁案例，測試經過，主要是PHP+mysql實現分頁，代碼來處百度空間，有興趣看的話能夠了解一下PHP是如何分頁的？php
<?php
$link = mysql_connect("localhost","root", "2855") //鏈接數據庫
or die("鏈接不上服務器：".mysql_error());
mysql_select_db("aming");
$ittype=$_GET['ittype'];
if($ittype==""){
echo "請輸入查詢條件";
exit;
}
$PageSize = 4;//每頁顯示記錄數
$StartRow = 0; //開始顯示記錄的編號 
//獲取須要顯示的頁數，由用戶提交
if(empty($_GET['PageNo'])){ //若是爲空，則表示第1頁
    if($StartRow == 0){
        $PageNo = $StartRow + 1; //設定爲1
    }
}else{
    $PageNo = $_GET['PageNo']; //得到用戶提交的頁數
    $StartRow = ($PageNo-1) * $PageSize; //得到開始顯示的記錄編號 $StartRow = ($PageNo - 1) * $PageSize;
}

//由於顯示頁碼的數量是動態變化的
//假如總共有一百頁，則不可能同時顯示100個連接
//而是根據當前的頁數顯示必定數量的頁面連接
//設置顯示頁碼的初始值
if($PageNo % $PageSize == 0){
    $CounterStart = $PageNo - ($PageSize - 1);
}else{
    $CounterStart = $PageNo - ($PageNo % $PageSize) + 1;
}

//顯示頁碼的最大值
$CounterEnd = $CounterStart + ($PageSize - 1);
?>

<html>
<head>
<title>分頁顯示記錄</title>
<link rel="stylesheet" href="include/style.css" type="text/css"></head>
<?php
/*$itname=$_POST['itname']; 
if($itname ==""){
echo "請輸入查詢條件";
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");

//獲取總記錄數
$RecordCount = mysql_num_rows($TRecord);

//獲取總頁數
$MaxPage = $RecordCount % $PageSize;
if($RecordCount % $PageSize == 0){
    $MaxPage = $RecordCount / $PageSize;
}else{
    $MaxPage = ceil($RecordCount / $PageSize);
}
