PHP 分页种

PHP 分页类
下面是我自己的分页类,可适当的修改 

<?php /**  * @name Pager's class  * @author Refer  * @copyright www.phpcq.com  * @version Alpha 1.0  * @todo 下拉菜单分页---From表单传&#20540;...可以根据自己的情况(采用GET传&#20540;)  *  */ class Pager{     /**      * startRow      *      * @var Int      */     public $startRow;     /**      * 页面的总数      *      * @var Int      */     public $pageTotal;     /**      *翻页&#20540;      *      * @var Int      */     public $offset;     /**      * 每页所显示记录数      *      * @var Int      */     public $pageSize;     /**      * get参数      *      * @var Int      */     public $get;     /**      * post参数      *      * @var Int      */     public $post;     /**      * 构造函数--初始化翻页类 （PS：^_^不错的php开发学习交流群：256271784，验证：gole，有兴趣的话可以加入进来一起讨论）     *      * @param Int $total      * @param Int $pageSize      */     public function __construct($total,$pageSize){         $this->get = (int)$_GET['startRow'];         $this->post = (int)$_POST['pageNums'];         $this->pageSize = $pageSize;         $this->pageTotal = ceil($total / $pageSize);         switch ($_GET['method']){             default:                 $this->startRow = 1;                 $this->offset = 0;             break;             case 'first':                 $this->first();             break;                 case 'previous':                 $this->previous();             break;                 case 'next':                 $this->next();             break;                 case 'last':                 $this->last();             break;             }     }      /**      * 首页方法      *      */     public function first(){         $this->startRow = 1;         $this->offset = ($this->startRow - 1) * $this->pageSize;    }     /**      * 上一页方法      *      */     public function previous(){         $this->startRow = $this->get - 1;         if ($this->startRow startRow = 1;         }         $this->offset = ($this->startRow - 1) * $this->pageSize;    }     /**      * 下一页方法      *      */     public function next(){         $this->startRow = $this->get + 1;         if ($this->startRow > $this->pageTotal) {             $this->startRow = $this->pageTotal;         }         $this->offset = ($this->startRow - 1) * $this->pageSize;    }     /**      * 最后页方法      *      */     public function last(){         $this->startRow = $this->pageTotal;         $this->offset = ($this->startRow - 1) * $this->pageSize;    }     /**      * 下拉菜单翻页      *      * @return Int      */     public function numPages(){         if ($this->post) {             $pageNums = "<option>$this->post</option>";             $this->startRow = $this->post;             $this->offset = ($this->post - 1) * $this->pageSize;        }         for ($i = 1; $i pageTotal;$i++){             if ($i != $this->post) {                 $pageNums .= "<option>$i</option>";             }         }         return $pageNums;     }     /**      * 当前是第几页      *      * @return Int      */     public function noncePage(){         if ($this->post) {             return $this->startRow = $this->post;         } else {             return $this->startRow = $this->startRow;         }     } } 

调用方法: 

$total = $total->total();//总记录             $pageSize = 15;//每页显示的记录             $pager = new Pager($total,$pageSize);             if ($pager->post){$startRow = $pager->noncePage();}             $startRow = $pager->startRow;             $pager->numPages();             $article->query("SELECT * FROM `categories` as c,`articles` as n WHERE c.id = n.pid                    ORDER BY n.id DESC LIMIT $pager->offset,$pageSize");             while ($article->fetchArray()) {                 $article->data['content'] = mb_substr(strip_tags($article->data['content']),0,40,'utf-8');                 $articleIndex[] = $article->data;                         }             $article->free();         } else {             header("location:?act=login");         }         $view->view->assign('startRow',$startRow);//caption         $view->view->assign('total',$total);//caption         $view->view->assign('pageNums',$pager->numPages());//pageNums         $view->view->assign('noncePage',$pager->noncePage());//pageNums         $view->view->assign('pageTotal',$pager->pageTotal);//pageTotal  

模板页面: 

<!--{if $pageTotal > 1}-->  

Pager: First Previous Next Last
