PHP won't work: plain code

[Matiss]

Hello.

I'm a newcomer to programming. I downloaded the newest version of XAMPP, installed it, turned on Apache. But even the simplest code in my browser will be showcased as a plain PHP code. Code is fine.
I've tried everything to fix it. I changed Apache port 80 to unassembled port. I tried every offered solution which can be found here:

And yes, I am writing it in my browser as URL, like http://localhost:1234/tutorials/text.txt

Please help. So far somehow I'm still interested in programming.

If you do not have the .php extension, your system will not know to process it as PHP.
