PHP统计排行，分页

1.分页参数

count 　　总数

firstRow 起始行

listRows 每一次获取记录数

list 每一页的记录（要与count对应一致就行）

2.分页对象

可以针对真实的数据表

也可以针对统计出来的数据表，或者说是虚拟的表

因为LIMIT是最后执行的，哪怕你进行group操作，哪怕你进行子查询

html

    font-size: 18px;

        $my_rank = $all[$opener_id]['rank']?$all[$opener_id]['rank']:'-';

        $this->assign('my_user_count',$my_user_count);

        $this->assign('page',$Page->show());

        $this->assign('list', $list);

        $this->display();

    }

    // 获取上一月开始与结束日期

    private function getLastMonthStartEndDay(){

        $thismonth = date('m');

        $thisyear  = date('Y');

        if ($thismonth == 1) {

            $lastmonth = 12;

            $lastyear  = $thisyear - 1;

        } else {

            $lastmonth = $thismonth - 1;

            $lastyear  = $thisyear;

        }

        $lastStartDay = $lastyear . '-' . $lastmonth . '-1';

        $lastEndDay   = $lastyear . '-' . $lastmonth . '-' . date('t', strtotime($lastStartDay)); //t 给定月份所应有的天数,28到31

        return array('lastStartDay'=>$lastStartDay,'lastEndDay'=>$lastEndDay);

    }

这里用的是thinkphp的分页类实现的。
