note 129834 added to function.session-gc

The session.gc() function does not seem to work alone. it deletes the data on the server but the data remains on the browser in the form of the cookie. the following code deletes the session files on the server but not on the browser. ini_set('session.gc_maxlifetime', 10); ini_set('session.gc_probability', 1); ini_set('session.gc_divisor', 1); // Start the session session_start(); $_SESSION['test'] = 'temporary data'; session_write_close(); // Wait for 15 seconds to ensure the session expires sleep(15); // Manually start the session again to trigger session handling session_start(); session_gc(); // Check if the session data is still available if (isset($_SESSION['test'])) { echo "Session is still active."; } else { echo "Session expired and file deleted."; } but this code delete the session files on the server and also deletes the cookie as well as making the super global empty: session_start(); $_SESSION['test'] = 'temporary data'; session_write_close(); // Wait for 15 seconds to ensure the session expires sleep(15); session_start(); // Manually trigger garbage collection setcookie(session_name(), '', time() - 10); $_SESSION = []; session_gc(); // Check if the session data is still available if (isset($_SESSION['test'])) { echo "Session is still active."; } else { echo "Session expired and file deleted."; } ---- Server IP: 45.112.84.4 Probable Submitter: 80.90.5.137 (proxied: 88.156.137.65) ---- Manual Page -- https://php.net/manual/en/function.session-gc.php Edit -- https://main.php.net/note/edit/129834 Del: integrated -- https://main.php.net/note/delete/129834/integrated Del: useless -- https://main.php.net/note/delete/129834/useless Del: bad code -- https://main.php.net/note/delete/129834/bad+code Del: spam -- https://main.php.net/note/delete/129834/spam Del: non-english -- https://main.php.net/note/delete/129834/non-english Del: in docs -- https://main.php.net/note/delete/129834/in+docs Del: other reasons-- https://main.php.net/note/delete/129834 Reject -- https://main.php.net/note/reject/129834 Search -- https://main.php.net/manage/user-notes.php
