How can the use_trans_sid variable impact session handling in PHP?

The use_trans_sid variable in PHP can impact session handling by enabling or disabling the transparent session id passing in URLs. If set to true, PHP will automatically append the session ID to all URLs in the output. This can potentially expose the session ID in the URL, making it vulnerable to session hijacking attacks. To solve this issue, it is recommended to set use_trans_sid to false in the php.ini configuration file or using ini_set() function in your PHP code.

// Disable transparent session id passing in URLs
ini_set('session.use_trans_sid', false);
