PHP中的默认会话时间和路径是什么。如何改变？

Posted 2021-02-22

Default session time in php is 1440 seconds (24 minutes) and the Default session storage path is temporary folder/tmp on server.

You can change default session time by using below code
 
<?php
// server should keep session data for AT LEAST 1 hour
ini_set('session.gc_maxlifetime', 3600);
 
// each client should remember their session id for EXACTLY 1 hour
session_set_cookie_params(3600);
?>
