In mannual,it says: creating new entries in the $_SESSION array will automatically register them as session variables, as if you called session_register(). If you are using $HTTP_SESSION_VARS/$_SESSION, do not use session_register(), session_is_registered() and session_unregister() unless you know internal of session module.
but , Example 1. <?php if (!isset($_SESSION['count'])) { $_SESSION['count'] = 0; } else { $_SESSION['count']++; } echo $count; ?> I only get a warning :Warning: Undefined variable: count in C:\WebShare\wwwroot\netk\5\test.php on line whie in the following example: <?php session_register('count'); if (!isset($_SESSION['count'])) { $_SESSION['count'] = 0; } else { $_SESSION['count']++; } echo $count; ?> it outputs 1(2,3......) why? thanks in advance. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
