PHP, getting variable from another php-file

Question

So I wonder if it is possible to get a variable from a specific php-file when the variable-name is used in multiple php-file. An example is this:

Answer 1

You could also use a session for passing small bits of info. You will need to have session_start(); at the top of the PHP pages that use the session else the variables will not be accessable

page1.php

Go to the other page

page2.php
