apache directory index file not showing

Question

I want to do 2 things in htaccess:

1. Strip extension from php files
2. serve dir/index when url is site/com/dir/

current code

RewriteCond %{REQUEST_FILENAME} !-f

RewriteRule ^([^\.]+)$ $1.php [NC,L]

/dir/ --> /dir/index be default apache behavior, but the rewriteRule break this logic. How to set up rewriteRule for stripping extension from file and not break dir --> dir/index logic?

Answer 1

updating

RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^([^\.]+)$ $1.php [NC,L]

to:

RewriteCond %{REQUEST_FILENAME} !-d 
RewriteCond %{REQUEST_FILENAME}\.php -f 
RewriteRule ^(.*)$ $1.php

solved the issue
