ID not being passed in RewriteRule

I am facing an issue while using .htaccess.The Re write rule is as follows.

RewriteRule ^user/([a-z]+)/?$ user.php?id=$1

incoming url : http://abhimanyu.localhost.com/user/home/ its redirecting to user.php but i am not getting the id. e.g $id= $_GET['id'];

any idea why???

FYI the re write logs

Try this:

RewriteRule ^user/([a-z]+)$ user.php?id=$1 [NC]

I can't tell if you're trying to capture the string immediately after /user/ or after /user/home. If you need to capture both, try this:

^user/([a-z]+)/(.+)$

You can access the first string after user with $1 and the second string with $2.

Try disabling the MultiViews option.
