Are there specific configuration settings in PHP that can be adjusted to control the display of session IDs in URLs, and how can these settings be modified?

To control the display of session IDs in URLs in PHP, you can adjust the "session.use_trans_sid" configuration setting. Setting this to "0" will prevent PHP from automatically adding session IDs to URLs. This can improve security by not exposing session IDs in URLs.

// Disable session ID in URLs
ini_set('session.use_trans_sid', 0);
