The first method requires editing the php.ini file, finding and modifying session.save_path to the specified directory, restarting the server after saving, and ensuring that the directory exists and has read and write permissions; the second method is suitable for a single application, using session_save_path() to set the absolute path before calling session_start(), which does not affect other projects. Notes include: Make sure the path is correct and readable
