How can the session data be properly maintained when navigating between different PHP scripts?

When navigating between different PHP scripts, session data can be properly maintained by starting the session at the beginning of each script and ensuring that the session is properly saved at the end of each script. This can be done by using the session_start() function at the beginning of each script and the session_write_close() function at the end of each script. 

<?php
// Start the session
session_start();

// Your PHP code here

// Save the session data
session_write_close();
?>
