[normal.php]
<?php ini_set("display_errors", "1"); session_save_path('./sss'); session_start(); ini_set("session.cache_expire", 20); ini_set("session.gc_maxlifetime", 20); ini_set("session.gc_probability ", 100); ini_set("session.gc_divisor ", 100); if(!isset($_SESSION['loginName'])){ header('Location: ./start.php'); } ?> <html> <body> Welcome. <?php echo $_SESSION['loginName'];?>!<br /> Login timestamp is <?php echo $_SESSION['loginTime'];?>!<br /> Login date is <?php echo date("Y-m-d h:i:s", $_SESSION['loginTime']);?>!<br /> <br /> session_name is <?php echo session_name();?>!<br /> <a href="./logout_act.php">Logout</a> </body> </html>
[logout_act.php]
<?php ini_set("display_errors", "1"); session_save_path('./sss'); session_start(); session_destroy(); header('Location: ./start.php'); ?>
