How can session.use_trans_sid affect the functionality of session variables in PHP?
Setting `session.use_trans_sid` to true can affect the functionality of session variables in PHP by enabling transparent session id propagation in URLs. This can lead to security risks as session ids may be exposed in URLs and potentially leaked to third parties. To prevent this, it is recommended to set `session.use_trans_sid` to false in your PHP configuration.
// Disable transparent session id propagation in URLs
ini_set('session.use_trans_sid', false);
