What are the security implications of using self-generated session IDs in PHP, especially in terms of user privacy and data protection?

Using self-generated session IDs in PHP can pose security risks as it may lead to predictable or easily guessable session IDs, making it easier for attackers to hijack sessions and gain unauthorized access to user data. To enhance security, it is recommended to use the built-in PHP session functions to generate secure session IDs. 

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

// Use the built-in PHP function to generate a secure session ID
session_regenerate_id(true);
