Sessions and PHP4

[Anon]

Can anyone help me with sessions in PHP4?

The following codes starts the session when the index.php file is loaded

<?
session_start();

if (!$PHPSESSID) {
session_register('LoginName');
session_register('LoginPassword');
}
?>

The user logins into the web via another page. Once the "login" button is clicked, yet another page "validate.php" will check the validity of the login. I also want to update the session variables. How?

Can anyone help?

To update a session variable You have
to first unregister it, update the
content and re-register the variable again.

Sorry to be a pain! But How

The way I do it is like this:

session_start();
(goes on top of every page)

Whenever I need a session var, all I do is:

$ses_login = "martin";
$ses_valid = true;
session_register("ses_login");
session_register("ses_valid");

To check if it's okay you could do:

if ( isset($ses_login) ) {
//session is set
} else {
//session not set
}

Or,

if ( $ses_valid ) {
//session is valid
}

And to clear a session var:

unset($ses_valid);
unset($ses_login);

Anyway, that's how I do it, of course there are other ways.
