Need a help on mod_rewrite

[bivaswap]

I am unable to do a suitable link for this type of link structure

http://mydomain.com/stats.php?act=user/id/546238

I want to make like

http://mydomain.com/id/546238/user.html

I am facing trouble because I can't change the act= value.

If this type of rule possible, or have any other idea ... please response!

Thank You!

I've never seen anything like

?act=user/id/546238

I usually see

?act=user&id=546238

Pretty URLs with .htaccess Rewriting Tips.

i have never seen this like before but rule for this will be

Options +FollowSymLinks
RewriteEngine on

RewriteRule _act_(.*)\.html stats.php?act=$1

Your new URL would be: _act_user/id/546238

[bivaswap]

?act=user/id/546238

This type of url is easily possible . When You are trying to send multiple value through $_GET[] in same parameter.
In this code I am sending username, ID both with 'act' parameter.

So there is nothing to worried about it.
