How can PHP developers ensure that session variables are properly passed between different PHP pages on the same server?

To ensure that session variables are properly passed between different PHP pages on the same server, developers should start the session on each page where they want to access or modify session variables. This can be done by calling session_start() at the beginning of each PHP file that needs to access session data. 

<?php
session_start();

// Access or modify session variables here
$_SESSION['username'] = 'JohnDoe';

// Other PHP code
?>
