Removing .php for one file only in htaccess

I'd like to change /comp.php to /comp but I have only found articles on how to remove .php completely and I don't want to do that, only want to do it for this one file.

 

Use This code in your .htaccess file and let me know if it works

RewriteEngine On
RewriteRule ^comp/?$ comp.php [NC]

Code (markup):

 

Thanks how could I make it a permanent redirect?

 

Why you want to make it a "Redirect"??
Redirection is for moving user from 1 URL to Another URL using htaccess

 

I meant in terms of if someone typed in /comp.php it should take them to /comp - I don't want to duplicate pages.

 

Could this be made in a permanent url? So it's a forced redirect?
