You can make sure that the file (!-f) or directory (!-d) that you're matching doesn't exist before the rewrite. That way you don't end up with a 500 loop with something like /index.php?page=index
. Additionally the ^
character is matching the beginning of the string, so if your original test was in a subdirectory it would not rewrite since you weren't allowing slashes.
This should work for any instance, however it will ONLY make the page variable the last string in the URI.
RewriteEngine On
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ([_a-zA-Z0-9]+)$ /index.php?page=$1 [R,L]
