What are the best practices for handling sessions and session variables in PHP?

When handling sessions and session variables in PHP, it is important to ensure proper security measures are in place to prevent session hijacking and data tampering. Best practices include setting a unique session name, using HTTPS for secure communication, regenerating the session ID periodically, and validating and sanitizing all session data. 

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

// Set a unique session name
session_name('my_unique_session_name');

// Regenerate the session ID periodically
if (mt_rand(1, 100) == 1) {
    session_regenerate_id();
}

// Validate and sanitize session data
$_SESSION['user_id'] = filter_var($_SESSION['user_id'], FILTER_SANITIZE_NUMBER_INT);
?>
