How can the use of the session_id() function impact the handling of session IDs in PHP scripts?

The use of the session_id() function can impact the handling of session IDs in PHP scripts by allowing developers to manually set or retrieve the session ID. This can be useful for scenarios where a specific session ID needs to be used or when integrating with external systems that require a specific session ID format. 

<?php

// Start the session
session_start();

// Set a custom session ID
$custom_session_id = 'my_custom_id';
session_id($custom_session_id);

// Use the session ID
echo "Session ID: " . session_id();

// Rest of your PHP code here

?>
