一、分页类设计Page.php

class Page {

public $pageSize=6;//每页显示记录数

public $res; //记录集

public $rowCount;//记录总数数

public $pageNow=1; //当前页

public $pageCount=1; //总页数

public $navigate; //导航

public $url; //地址

public $firstRow; //每页显示的第一条记录

public $rollPage; //分栏每页显示页数

public $startNum; //【1】

public $endNum;

public function setNav(){

$navigate="";

//本导航的起始页

if($this->startNum>1){

$jump=$this->startNum-$this->rollPage;

//$nav=$this->url."/pageNow/$jump";

$navigate.= "<< ";

}

for($start=$this->startNum;$start<=$this->endNum;$start++)

{

$navigate.="[{$start}]";

}

if($this->endNum<$this->pageCount)

{

$jump=$this->startNum+$this->rollPage;

$navigate.= ">> ";

}

$navigate.="第".$this->pageNow."页/共".$this->pageCount."页";

$this->navigate=$navigate;

}

public function setPage($url,$pageNow,$rowCount,$pageSize=6,$rollPage=4){

$this->url=$url;

$this->pageNow=$pageNow;

$this->rowCount=$rowCount;

$this->pageSize=$pageSize;

$this->rollPage=$rollPage;

$this->pageCount=ceil($this->rowCount/($this->pageSize+0.0));

$this->firstRow=($this->pageNow-1)*$this->pageSize;

$this->startNum=floor(($this->pageNow-1)/$this->rollPage)*$this->rollPage+1;

$this->endNum=$this->startNum+$this->rollPage-1;

if($this->endNum>$this->pageCount)

{

$this->endNum=$this->pageCount;

}

if($rowCount==0){

$this->pageNow=1;

$this->rollPage=1;

$this->firstRow=1;

$this->pageCount=1;

}

$this->setNav(); //字符串存储导航

}

}

?>

二、SqlHelper.class.php定义分页显示方法

public function excute_dql_page($sql1,$sql2,&$page){

//数据表信息分页

//sql1数据，sql2求行数

$result=mysql_query($sql1,$this->conn)or die(mysql_errno());

$arr=array();

while($row=mysql_fetch_assoc($result)){

$arr[]=$row;

}

mysql_free_result($result);

$result=mysql_query($sql2,$this->conn) or die(mysql_errno());

if($row=mysql_fetch_row($result)){

$page->pageCount=ceil($row[0]/$page->pageSize);

$page->rowCount=$row[0];

}

mysql_free_result($result);

//实现导航条

$page->res_array=$arr; //数组存储记录集

$fenyePage->setNav();

return $arr;

}

三、使用分页（userList.php）

header("content-type:text/html;charset=utf-8");

require_once 'SQLHelper.class.php';

require_once 'UserService.class.php';

echo"用户信息表
";

echo"

";

//创建fenyePage并设置属性值

$page=new Page();

$page->url="userList.php";

$page->pageNow=1;

if(isset($_GET['pageNow'])){

$page->pageNow=$_GET['pageNow'];

}

//创建Service负责产生一个记录集（分页后的）

$page->setPage($url,$pageNow);

$userService=new UserService();

$userService->getUserListByPage($fenyePage);

foreach ($page->res_array as $row){

$id=$row['id'];

echo"

";

//print_r($row['id']);

}

echo"

id	name	删除	修改
{$row['id']}	{$row['name']}	删除	修改

";

echo $fenyePage->navigate;

?>

到第 页
