Pass PHP variable from one page to another and to another [duplicate]

Answer 1

Check the PHP documentation for sessions. There are many examples of how to do this.

http://www.php.net/manual/en/session.examples.basic.php

Answer 2

Use a $_SESSION superglobal: http://us3.php.net/manual/en/reserved.variables.session.php

You'll need to use a session_start() function at the beginning of any page you want to maintain session data for. After that, you can just assign to and retrieve from $_SESSION['username'].
