可以mod_rewrite的做数学题？ [英] Can mod_rewrite do math?

问题描述

我计划我的网站转换为新的CMS，但我想用mod_rewrite的老无缝链接重定向到新的位置。

I am planning to convert my website to a new CMS, but I would like to use mod_rewrite to seamlessly redirect old links to their new locations.

美中不足的是，我的新博客将不会有同样的文章编号，如旧，因为我会在他们的第一个导入一些较老的博客条目。因此，我的mod_rewrite需要采取像 old.php？文章的URL = 125 ，做加法找出新的文章编号（比如+200，在这个例子），并重定向到 new.php？I = 325 。

The catch is that my new blog will not have the same article numbers as the old, because I'll import some older blog entries in their first. Thus, my mod_rewrite would need to take a URL like old.php?article=125, do the addition to figure out the new article number (say +200, for this example), and redirect to new.php?i=325.

能否mod_rewrite的做自己的加法，还是我将需要某种形式的'助手'脚本来做到这一点？

Can mod_rewrite do the addition on its own, or am I going to need some kind of 'helper' script to do that?

推荐答案

它不能做数学。也许你想使用改写地图。

It can not do math. Maybe you want to use a rewrite map.
