Where to start to make a simple server for the game?

Question

PHP

Hello everyone) I'll try to be brief ..
There is a mobile toy.
You need to store user data on the server side.
And when entering the game, pull the profile from the database once.
Where do I start to implement this?
The main criterion is ease of study and speed of implementation.
P.S. I'm learning programming on my own and I love it a lot, but now I'm very limited in time and any of your advice will be very, very important to me)))))

Answer 1

You need to start by drawing up a diagram of the data exchange between the client and the server.
Then - select technologies.
Then - the desired language for coding.
If the language is not important - take PHP as a basis.
