　　1、分页类

<?php
class PageView{
/**页码**/
public $pageNo = 1;
/**页大小**/
public $pageSize = 20;
/**共多少页**/
public $pageCount = 0;
/**总记录数**/
public $totalNum = 0;
/**偏移量,当前页起始行**/
public $offSet = 0;
/**每页数据**/
public $pageData = array();
/**是否有上一页**/
public $hasPrePage = true;
/**是否有下一页**/
public $hasNextPage = true;
public $pageNoList = array();
public $pageUrl = '';
public $parameterArray = null;
/**
*
* @param unknown_type $count 总行数
* @param unknown_type $size 分页大小
* @param unknown_type $string
*/
/**
*
* @param $count总行数
* @param $size分页数【默认20】
* @param $pageNo当前页
* @param $pageData分页数据
* @param $pageUrl分页链接url,1、普通url链接 2、js页面跳转 格式 javascript:funcname
* @param $parameterArray分页url参数 格式array('id'=>1,'type'=>'add')
*/
public function __construct($count=0, $size=20,$pageNo=1,$pageData =array(),$pageUrl='',$parameterArray=null){
$this->totalNum = $count;//总记录数
$this->pageSize = $size;//每页大小
$this->pageNo = $pageNo;
//计算总页数
$this->pageCount = ceil($this->totalNum/$this->pageSize);
$this->pageCount = ($this->pageCount<=0)?1:$this->pageCount;
//检查pageNo
$this->pageNo = $this->pageNo == 0 ? 1 : $this->pageNo;
$this->pageNo = $this->pageNo > $this->pageCount? $this->pageCount : $this->pageNo;

$this->parameterArray = $parameterArray;
}
/**

*/
private function generatePageList(){
$pageList = array();
if($this->pageCount <= 9){
for($i=0;$i<$this->pageCount;$i++){
array_push($pageList,$i+1);
}
}else{
if($this->pageNo <= 4){
for($i=0;$i<5;$i++){
array_push($pageList,$i+1);
}
array_push($pageList,-1);
array_push($pageList,$this->pageCount);

array_push($pageList,1);
array_push($pageList,-1);

array_push($pageList,1);
array_push($pageList,-1);
array_push($pageList,$this->pageNo -2);
array_push($pageList,$this->pageNo -1);
array_push($pageList,$this->pageNo);
array_push($pageList,$this->pageNo + 1);
array_push($pageList,$this->pageNo + 2);
array_push($pageList,-1);
array_push($pageList,$this->pageCount);
}
}
return $pageList;
}
/***
* 创建分页控件
* @param
* @return String
*/
public function echoPageAsDiv(){
$pageList = $this->generatePageList();
$pageString ="<div class='pagination'><div class='page-bottom'>";
if(!empty($pageList)){

continue;

continue;
}
//                    $pageString = $pageString ."<a href=\"javascript:" .$this->jsFunction . "(" . $p . ")\">" . $p . "</a>";

}

　　2、分页类使用实例代码

<?php
include 'PageView.php';
header("Content-type:text/html;charset=utf-8");
$pageNo = $_GET['page'];
$pageSize = 1;
//分页数据
$pageData = array (array ('id' => 1 ), array ('id' => 2 ), array ('id' => 3 ), array ('id' => 4 ) );
//取得总行数
$count = 21;
$test = array('type'=>1,'name'=>'add');
$pageUrl = '';
$pageUrl = 'javascript:tabPage';
//$pageParameterArray = null;
$pageParameterArray = array('id'=>1,'type'=>'add');
//创建分页器
$p = new PageView ( $count, $pageSize, $pageNo, $pageData ,$pageUrl,$pageParameterArray);
//生成页码
$pageViewString = $p->echoPageAsDiv ();
$pageData = $p->pageData;
echo '<style type="text/css">
<!--
.pagination {font-family: Tahoma;overflow: hidden; padding-top: 12px; text-align: center;}
.pagination-tab { margin-bottom: 20px;}
.pagination a, .pagination .page-cur, .pagination .page-prev_g, .pagination .page-prev, .pagination .page-next, .pagination .page-next_g, .pagination .page-break, .pagination .page-skip {

-->
</style>';
echo $pageViewString;
echo "<script type='text/javascript' src='/test/jquery.min.js'></script>
<script type='text/javascript'>
function tabPage(tid,id,type){
alert(tid);
}
</script>";
