/*====对数据的记录进行分页显示=====;;
一张页面有连续的十个页面的连接;;
一页可显示$limit_row条记录信息;;
并有下十页和上十页翻页功能;;
===================================;;

------需传入值$total_row;$limit_row;$pagename;-----;;
$total_row为所选查询结果的总行数;;
$limit_row为每页显示的最大行数;;
$pagename为返回显示页面名称。（不带后缀名）;;
----------------------------------------------------;;

----------------------------------------------------;;
$page当前所读页面;;
$total_page为共可分为几页.;;
$row_begin为从第几行开始读;;
$row_end为读到第几行为止;;
