Make interpret a file as PHP code on webserver

It's possible to interpret file as PHP code on webserver without standard extension ? For some reason, the last three letters of my file should be gif. I try to make what is there after .php optional for the server to interpret my code.

Examples of attempts :

• scriptcode.php#gif


• scriptcode.php?gif


• scriptcode.php::$gif (or :gif / $gif)


• scriptcode.php\00gif (or %00)

I read a lot of things, but never anything that works on my side. So, it's feasible ?
