htaccess 301 redirect from ?id=1 to mysite.com

I'm trying to get all the dynamic links like these:
mysite.com/index.php?id=1
mysite.com/index.php?id=2
mysite.com/index.php?id=3
etc.

to 301 redirect to:
mysite.com

Any help would be appreciated.
Thanks.

 

You're being very vague so I'm going to show you a php solution:

 

Try this in .htaccess:

RewriteEngine on
RewriteCond %{QUERY_STRING} ^id=
RewriteRule ^index\.php$ http://www.my_site.com/? [L,R=301]

Code (markup):

I believe that Isaak's suggestion is going to give a 302 redirect.

Just an FYI. This is what I finally got to work:

RewriteCond %{QUERY_STRING} ^id=([0-9]+)$ [NC]
RewriteRule ^index.php$ [url]http://www.mysite.com/page.php?id=%1[/url] [R=301,L]

Code (markup):

Thanks for the help.
