In what situations would it be recommended to manually set the session ID using session_id() in PHP?

It may be recommended to manually set the session ID using session_id() in PHP when you want to control the session ID generation process or if you need to set a specific session ID for security reasons or for integration with external systems. This can be useful in scenarios where you want to ensure uniqueness or predictability of session IDs. 

<?php
// Manually set the session ID
session_id('custom_session_id');

// Start the session
session_start();

// Your code here
?>
