谁能帮小弟解释一下下面这个程序，我看了半天也看不懂。

[xizi2002]

根据条件进行搜索,然后显示出搜索的结果
主要看其中的
$StrSql="select designerid,designername from new_designer where $where inuse='1' order by designername";
这一句作为整个分界线,上面的为这一句的生成部分,后面的为这一句的显示部分
(包括显示上一页,下一页的链接等)

这个while($Row&&$j<$PageSize)怎么解释？
另外if($CurPage=="") $CurPage=1;中的CurPage是不是当前页的页码（我猜的）？
如果是的话，你又是如何知道他是当前页的页码的？

[kjeny2002]

当前页是通过计算得到的。

总记录数/每页显示数

[tomyhenry]

我希望你能给点分。我的分系统搞错了。没分问了。所以……

[Cain]

up一下，谁能解释的更清楚一点？
