Dynamic Value in variable php

Question

I have a Variable with a dinamic value inside.

My problem is, I can't patch this Variable anywhere when I change to another PHP file. I tried to register this Variable in a XML file, into the mysql data base, with constants, and nothing works, the value of my Variable will always reset.

Is there a way for me to freeze that variable value and use it later?

Thanks in advance.

PS: i looked for weeks in here and other places. Because im human I might have failed to realise hiden anwsers. If for some reason this is a duplicate please indicate the post, im very tired by now I might not be thinking strait.

EDIT:

The code is:

$actual_link = (isset($_SERVER['HTTPS']) ? "https" : "http") . "://$_SERVER[HTTP_HOST]$_SERVER[REQUEST_URI]";

I recieve page1.php?id=51

Then I use $id = $_GET['id'];

To get the ID value (51)

And this is the value I would like to "freeze" to use in page2.php because if I navigate to page2.php the $id is gone.

Can you supply some code to show what you mean. I'm not sure I understand your question. — Andreas

What do you mean by "patch this variable when changing to another file" in this context? — Chris Bornhoft

persistent variable options: a file, a database; if its persistent to one user : session\coockie. if you need help with your chosen method, you need to show us the code used, and explain the issues you had with the code — user8011997

You should store the $_GET['id'] into a session variable. Once you get to page 2 you can just retrieve the value. — dokgu
