You would use GET the same way, but you'll have to modify routing to match the url... See tutorials to get an idea, because it's a kinda broader topic, for instance here:
http://code.tutsplus.com/tutorials/using-htaccess-files-for-pretty-urls--net-6049
Routing php query using .htaccess
Etc. Just search for url routing
or url rewriting
if these links ever stop being available.
You'll just have to specify few rewrite rules and you're good to go.
If you use some framework later, these tend to do some stuff for you, but you'll have to specify some rules for routing anyway, so it's a good idea to understand the basics with .htaccess first.
