不懂的.htaccess 菜鸟求帮助

代码如下
<IfModule   mod_rewrite.c>
RewriteEngine   On
RewriteBase   /
RewriteRule   ^article/([0-9]+).html$   article.php?act=detail&id=$1   [L]
RewriteRule   ^article/([0-9]+).html$   article.php?act=cate&cid=$1   [L]
</IfModule>

我对这个不懂,求帮忙....哪位能写个正确...感激不尽...

这样试试，效果为article/ab-12.html
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteRule article\/([a-zA-Z]{1,})-([0-9]{1,}).html$ article.php?act=$1&id=$2
RewriteRule article\/([a-zA-Z]{1,})-([0-9]{1,}).html$ article.php?act=$1&cid=$2
</IfModule>
