Session lost after page redirect in php

Question

When I use php header redirection all session variables are lost... Some people say that adding exit(); just after the header(\"\"); will solve the problem but it doesn\'t s

Answer 1

I was trying to set the session id of my own using :

But as the documentation says, you have to use this before

session_start();

Using it after session_start(), clears the session parameters.
