Are there any best practices to follow when working with sessions in PHP?

When working with sessions in PHP, it is important to follow best practices to ensure security and efficiency. Some best practices include regenerating session IDs to prevent session fixation attacks, setting appropriate session cookie parameters, and validating session data to prevent session hijacking. 

// Start the session
session_start();

// Regenerate session ID to prevent session fixation
session_regenerate_id(true);

// Set session cookie parameters
session_set_cookie_params([
    'lifetime' => 3600, // 1 hour
    'path' => '/',
    'domain' => 'example.com',
    'secure' => true,
    'httponly' => true
]);

// Validate session data
if (!isset($_SESSION['user_id'])) {
    // Redirect or handle unauthorized access
}
