What are the implications of placing the session folder within or outside the DocumentRoot in terms of security and accessibility?

Placing the session folder outside the DocumentRoot is more secure as it prevents direct access to session files by users. It also reduces the risk of session data being exposed in case of a server misconfiguration. However, it may require additional configuration to ensure proper session handling.

// Set the session save path outside the DocumentRoot for improved security
session_save_path('/path/to/session/folder');
