mod_rewrite error 404 if .php

Question

I rewrite my urls to be user friendly. For example I have a page called user.php that I rewrite to /user. But a user can still use user.php. Can I redirect to a 404 if they request a page with a .php extension?

Options -MultiViews +FollowSymlinks -Indexes
RewriteEngine on


RewriteRule ^user/([0-9]+)$ user.php?id=$1 [L,QSA]

Thanks.

Answer 1

RewriteCond %{THE_REQUEST} \.php[\ /?].*HTTP/
RewriteRule ^.*$ - [R=404,L]

Answer 2

This should do the trick, I think:

RewriteRule (.*)\.php$ path/to/your/404file [L]

Answer 3

A 301 redirect may be more appropriate for this task.
