Disabling PHP within a specified folder, except for certain files?

[Kadence]

I'd like to turn PHP off within a folder, with the exception of certain files (e.g. disabling PHP for all files but test1.php and test2.php, or test*.php). I believe PHP can be turned off for a folder by placing "php_flag engine off" within that folder's .htaccess, but how can I still have certain specific php files work?

writing this in the hpptd.conf file will restrict those php files to parse.

<Location />
ForceType text/html

Edit: Saw only your first post earlier. I'll look up ForceType, thanks.
