本人原创的代码,高手看来,也许流程笨拙点,但是很实用.看者要顶啊
/*---------------------------------------------------------------//
* 函数说明:分页函数 page($sql,$pagesize="30")
* $sql 查询语句(除limit外,可带排序或者条件限制)
* 如 select * from stu where time between "1" and "30";
* $pagesize 每页的显示条数
* ## 可输出数组$arr的值,说明如下:
* $arr["first"] 首页及地址
* $arr["page_pre"] 上一页及地址
* $arr["all"] 当第几页和总页数
* $arr["page_next"]下一页及地址
* $arr["last"] 末页及地址
