.htaccess php删除子文件夹

Currently using

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

However moving a php script that uses this to a subfolder and having something else in the main directory.

What's the best way to allow the above to work in the subfolder only?

Just move the file to the sub folder along with the php file
