How can session ID settings in the php.ini file affect the security and functionality of a PHP application?

Session ID settings in the php.ini file can affect the security and functionality of a PHP application by determining how session IDs are generated, stored, and managed. For example, if the session.use_strict_mode setting is enabled, PHP will only accept session IDs generated by the PHP session module, preventing session fixation attacks. Additionally, setting session.cookie_httponly to true can help prevent cross-site scripting attacks by making the session cookie inaccessible to client-side scripts.

// Set session ID settings in the php.ini file
ini_set('session.use_strict_mode', 1);
ini_set('session.cookie_httponly', 1);
