How can the use of ini_set() affect PHP session functionality?

Using ini_set() to change session configuration settings can affect PHP session functionality by altering the behavior of sessions in ways that may not be intended. It is recommended to set session configuration options in the php.ini file or using session_set_cookie_params() before starting the session. This ensures consistent behavior across all scripts that use sessions.

// Set session configuration options before starting the session
session_set_cookie_params(3600, '/', '.example.com', true, true);
session_start();
