Need help with PHP

Question

Hey everyone! I just started learning some php and was wondering if it is possible to keep all your php in different file than html.

I would like to have a separate php file for contact us form section and then a separate file for some info that will also go through another form.

Can it work like that?

Answer 1

read about include and .php files :) + MVC

Answer 2

read something about ajax.
that way you have html files and can use php files for requests only saves some resources
