php相当简单的分页类

答案：class Helper_Page{ 

/** 总信息数 */ 
var $infoCount; 
/** 总页数 */ 
var $pageCount; 
/** 每页显示条数　*/ 
var $items; 
/** 当前页码 */ 
var $pageNo; 
/** 查询的起始位置　*/ 
var $startPos; 
/** 下一页　*/ 
var $nextPageNo; 
/** 上一页　*/ 
var $prevPageNo; 

function Helper_Page($infoCount, $items, $pageNo) 
{ 
$this->infoCount = $infoCount; 
$this->items = $items; 
$this->pageNo = $pageNo; 
$this->pageCount = $this->GetPageCount(); 
$this->AdjustPageNo(); 
$this->startPos = $this->GetStartPos(); 
} 
function AdjustPageNo() 
{ 
if($this->pageNo == '' || $this->pageNo < 1) 
$this->pageNo = 1; 
if ($this->pageNo > $this->pageCount) 
$this->pageNo = $this->pageCount; 
} 
/** 
* 下一页 
*/ 
function GoToNextPage() 
{ 
$nextPageNo = $this->pageNo + 1; 
if ($nextPageNo > $this->pageCount) 
{ 
$this->nextPageNo = $this->pageCount; 
return false; 
} 
$this->nextPageNo = $nextPageNo; 
return true; 
} 
/** 
* 上一页 
*/ 
function GotoPrevPage() 
{ 
$prevPageNo = $this->pageNo - 1; 
if ($prevPageNo < 1) 
{ 
$this->prevPageNo = 1; 
return false; 
} 
$this->prevPageNo = $prevPageNo; 
return true; 
} 
function GetPageCount() 
{ 
return ceil($this->infoCount / $this->items); 
} 
function GetStartPos() 
{ 
return ($this->pageNo - 1) * $this->items; 
} 
}
