重写配置文件页面的URL

How do I use .htaccess to rewrite:

mysite.com/profile/[username]

go to:

mysite.com/profile.php?id=[username]

I don't want to have to reload the page just change the URL to make it look good.

Any help is appreciated.

This is the htaccess rule that should get you started:

RewriteEngine On

RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule profile/(.+) profile.php?id=$1
