How can I create a wifi hotspot and share my localhost across

Question

I know how to make a wifi hotspot on my linux machine(using Manjaro with i3 DE), also I managed to connect my iPhone to the wifi connection I made, but the goal is to start lampp and make my iPhone and other devices, like another PC, a smart TV have access to my localhost server.

Is it possible to make this even without an Internet connection? Like without my wifi router on, or without any ethernet? I guess you could say that is somehow a fake hotspot without access to the outer world :D

Basically I need something like a wifi lan, so if anybody could suggest some ideas, software or some tutorials/documentation on net, I would be grateful.

Solution

Thanks for the replies, actually it worked by itself :D I had to create the hotspot via NetworkManager, and then start lampp, or the other way, the order doesn't matter.

The problem was that I tried to access localhost, instead of the my IP :D So after I tried to access my IP, it worked as desired. Sorry for wasting your time, I was just a bit confused.
