Are there any specific PHP functions or settings that can help in preserving session data while navigating a website?

When navigating a website, session data in PHP can be lost due to various reasons such as session timeouts or browser settings. To preserve session data, you can increase the session timeout value and use session_regenerate_id() to prevent session fixation attacks. Additionally, you can ensure that session cookies are set to be accessible across subdomains to maintain session data consistency. 

// Increase session timeout value
ini_set('session.gc_maxlifetime', 3600); // 1 hour

// Set session cookie parameters
session_set_cookie_params(0, '/', '.example.com');

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