note 129695 added to function.setcookie

In any web browser there is a very commonly used option "Open previous windows and tabs" which is disabled by default, but many people enable it. When this option is active, the web browser, when closing and reopening, instead of executing the termination and starting a new session, saves and restores the current session along with session cookies and sessionStorage. Both session cookies and sessionStorage, contrary to expectations, can live for a very long time until the user closes the tab before closing the web browser. If you want a cookie, for example with a time offset, to be guaranteed to have a short lifetime, you should explicitly specify this short lifetime, rather than relying on self-deletion on the session cookie. ---- Server IP: 45.112.84.4 Probable Submitter: 80.90.5.137 (proxied: 94.181.30.64) ---- Manual Page -- https://php.net/manual/en/function.setcookie.php Edit -- https://main.php.net/note/edit/129695 Del: integrated -- https://main.php.net/note/delete/129695/integrated Del: useless -- https://main.php.net/note/delete/129695/useless Del: bad code -- https://main.php.net/note/delete/129695/bad+code Del: spam -- https://main.php.net/note/delete/129695/spam Del: non-english -- https://main.php.net/note/delete/129695/non-english Del: in docs -- https://main.php.net/note/delete/129695/in+docs Del: other reasons-- https://main.php.net/note/delete/129695 Reject -- https://main.php.net/note/reject/129695 Search -- https://main.php.net/manage/user-notes.php
