What best practices should be followed when using session_start() in PHP scripts?

When using session_start() in PHP scripts, it is important to call it at the beginning of the script before any output is sent to the browser. This ensures that session data can be properly stored and retrieved. Additionally, it is recommended to use session_regenerate_id() to prevent session fixation attacks by generating a new session ID each time a user logs in. 

<?php
session_start();
session_regenerate_id(true);

// Rest of your PHP code here
?>
