How to create an authorization and a personal account on the site?

Question

PHP

I am a beginner web developer. I am unable to create a personal account. If authorization, although small, already exists (When you go to another page, the session disappears), then I can’t make a personal account. I have scoured the internet but have not found anything. I'm not asking you to do everything for me. Leave resources where you can learn it.

Answer 1

session_start();
at the beginning of each page in the LC must be present in order to get access to reading the values ​​of session variables.

Answer 2

Look towards frameworks. There are many video courses on youtube that solve your problem.
