本文实例分析了thinkPHP统计排行与分页显示功能。分享给大家供大家参考，具体如下：
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

} else {

}
$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。
