本文实例讲述了php简单分页类实现方法。分享给大家供大家参考。具体如下:

复制代码 代码如下:
class PageModel { 
    /**
     * 获取分页数组
     * @param unknown $page 当前页面数
     * @param unknown $goodsCount 商品总数
     * @param unknown $pageLength 每个页面展示页面数
     */ 
    public static function getPageArr($page, $goodsCount, $pageCountLength, $pageLength) { 
        //页面总数 
        $allPageCount = ceil($goodsCount / $pageLength); 
       //如果页面总是比长度短,设定页面长度为页面总数 
       if ($allPageCount            $allPageCount = ceil($goodsCount / $pageLength); 
       } 
        //总页面数一页展示完 
        if ($allPageCount             for ($i = 0; $i                 $arr[] = array('page' => $i + 1); 
            } 
            return $arr; 
        } 
        //前后的长度 
        $halfLength = floor($pageCountLength / 2); 
        //因为太小,所以放原来位置,左边 
        if ($page             $arr = array(); 
            for ($i = 0; $i                 $arr[] = array('page' => $i + 1); 
            } 
            return $arr; 
        } 
        //太大,只取到边缘,超出也只取到边缘 
        if ($page > $allPageCount - floor($pageCountLength / 2)) { 
            for ($i = -$pageCountLength; $i                 $arr[] = array('page' => $allPageCount + $i + 1); 
            } 
            return $arr; 
        } 
        //中间的数,把中间的取出来 
        for ($i = -$halfLength; $i             $arr[] = array('page' => $page + $i); 
        }
        return $arr;
    }
}

希望本文所述对大家的php程序设计有所帮助。
