php分頁類，用的是zendframe框架

文件名：page.impl.php

class PageImpl {
   
    private $sql;
   
    private $page;

    private $totalRecord;
   
    private $totalPage;
   
    private $nextPage;
   
    private $prePage;
   
    private $pageSize;
   
    public function __construct($sql, $page, $size=20) {
        $this->sql = $sql;
        $this->page = $page ? $page : 1;
        $this->pageSize = $size;
    }
   
    public function queryResult($dbAdapter) {
        $this->filterSql();
        $result[0] = $dbAdapter->fetchAll($this->sql);
        $pageSql = "SELECT FOUND_ROWS() as count";
        $pageResult = $dbAdapter->fetchAll($pageSql);

        }

        $pages['page'] = $this->page;
        $pages['total_page'] = $this->totalPage;
        $pages['total_record'] = $this->totalRecord;
        $pages['next_page'] = $this->nextPage;
        $pages['pre_page'] = $this->prePage;
        $pages['page_range'] = $this->pageRange(10);
       
        return $pages;
    }
   
    private function filterSql() {
        if ($this->page == 1) {
            $this->sql .= " LIMIT 0," . $this->pageSize ;
        }else {

        }
        $this->sql = preg_replace("/^select/i", "SELECT SQL_CALC_FOUND_ROWS", $this->sql);
    }   
   
    private function pageList() {
        if (!$this->totalRecord) {
            return false;
        }
        if (($this->totalRecord % $this->pageSize) == 0) {
            $this->totalPage = (integer)($this->totalRecord / $this->pageSize);
        }else {
            $this->totalPage = (integer)($this->totalRecord / $this->pageSize + 1);
        }
        if ($this->page > $this->totalPage) {
            return false;
        }elseif ($this->page < $this->totalPage) {
            $this->nextPage = $this->page + 1;
        }else {
            $this->page = $this->totalPage;
        }
       
        if ($this->page > 1) {
            $this->prePage = $this->page - 1;
        }else {
            $this->prePage = 1;
        }
       
        return true;
    }

    private function pageRange($range) {
        if (2 > $range) {
            $range = 2;
        }
       
        $halfRange = ceil($range / 2);
        $newRange = $halfRange * 2;
        $tmp = ($halfRange > $this->page) ? $newRange : $this->page + $halfRange;
        $this->totalPage = $this->totalPage ? $this->totalPage : 1;
        if ($this->page > $this->totalPage) {
            $this->page = $this->totalPage;
        }
        $max = ($this->totalPage <= $tmp) ? $this->totalPage : $tmp;
        $min = ($this->totalPage <= $tmp) ? (($newRange < $max) ? $max-($newRange-1) : 1) : (($halfRange > $this->page) ? 1 : $this->page - $halfRange + 1);
       
        return range($min, $max);
    }
}

 

2.通過sql語句，獲取數據進行分頁friend.php

 

class Friend extends Zend_Db_Table{

    protected $_name = 'friend';//數據庫表名
    const PAGE_COUNT =20;//每頁20條

    public function __construct(){
        parent::__construct();
    }

 

    public function pageList($page) {
        $db = $this->getAdapter();
        $sql = "select * from " . $this->_name ;
        $pageImpl = new PageImpl($sql, $page, self::PAGE_COUNT);

        return $pageImpl->queryResult($db);
    }

}

 

 

3.調用分頁方法FriendController.php

 

class FriendController extends ActionImpl{
    public function init() {
        parent::init();
    }
   
    public function indexAction() {
        $page = (!isset($this->params['p']) || !intval($this->params['p'])) ? 1 : intval($this->params['p']);

        $objFriend = new Friend();
        $return = $objFriend->pageList($page);

        $list = $return[0];
        $pages = $return[1];
        $pages['link'] = "/friend/";

        $this->smarty->assign('result', $list);
        $this->smarty->assign('page',$pages);

    }

}

 

 

4.顯示在頁面上index.tpl

 

{foreach from=$result item=value key=key}
            <tr>
              <td  align="center" width="241">{$value->name}</td >
              <td  align="center" width="425">{$value->url}</td >
              <td  align="center" width="127">[<a href="/friend/update/?id={$value->id}">修改</a>]</td >
              <td  width="117" asign="center">[<a href="/friend/del/?id={$value->id}" οnclick="return delpic();">刪除</a>]</td >
            </tr>
            {/foreach}
          </table>
           <div style="text-align:center;font-size:12px;">
            共({$page.total_record})條 {$page.total_page}頁
            <a href="{$page.link}?p={$page.pre_page}">上一頁</a>
            {foreach from=$page.page_range item="r"}
                {if $r == $page.page}[{$r}]{else}<a href="{$page.link}?p={$r}">{$r}</a>{/if}   
            {/foreach}
            <a href="{$page.link}?p={$page.next_page}">下一頁</a>
            <input type="text" style="width:30px;" name="page"/>
            <input type="button" value="GO"/>
        </div>
