May i ask what the advantage of storing objects in session is ? Does it
cause overhead ? Like should i store the most common classes like the db and
auth class in a session ?

I do not have error logging enabled. All errors are displayed to the
screen. This is not a production server I am testing on.

I wasn't showing the method call, because it isn't what's causing the
problem (well I don't think so, anyway). The problem is the session not
unserializing for some reason. Here is the code.
Page one:
require_once('UserAuth.inc');
$auth = new UserAuth('file', array('file' => '/tmp/password'));
if (!empty($_POST['username']) && !empty($_POST['password'])) {
//$auth = new UserAuth('file', array('file' =>
'/tmp/password'));
if ($login = $auth->login($_POST['username'], $_POST['password'],
$secret_word)) {
session_start();
$_SESSION['auth'] = serialize($auth);
//session_register("auth");
//var_dump($_SESSION['auth']);
header('Location: http://example/code/php/test.php');
//$auth->debug();
die();
} else {
var_dump($login);
echo 'Test failed!';
die();
}
}
<More code down here>
Page two:
require_once('UserAuth.inc');
session_start();
if (!empty($_SESSION['auth'])) {
var_dump($_SESSION['auth']);
$userauth = unserialize($_SESSION['auth']);
//$auth = $_SESSION['auth'];
var_dump($userauth);
}
