What are the best practices for managing sessions in PHP to ensure security and efficiency?

To ensure security and efficiency when managing sessions in PHP, it is important to use secure session handling techniques such as using HTTPS, setting secure session cookies, regenerating session IDs, and validating session data to prevent session hijacking and other security threats. 

<?php
// Start secure session
session_set_cookie_params(0, '/', '', true, true);
session_start();

// Regenerate session ID
session_regenerate_id(true);

// Validate session data
if (!isset($_SESSION['user_id'])) {
    // Redirect to login page or handle unauthorized access
    header('Location: login.php');
    exit();
}
?>
