What are the potential implications of setting session.use_trans_sid to "On" or "Off" in PHP configurations for session handling?

Setting `session.use_trans_sid` to "On" can potentially expose session IDs in URLs, making them vulnerable to session fixation attacks. It is generally recommended to set `session.use_trans_sid` to "Off" to prevent this security risk.

// Set session.use_trans_sid to Off
ini_set('session.use_trans_sid', 0);
