Check if User Connected?

[vindikato]

I would like to know when an user is connected...
and use a specific design when is not

I find this in util.inc.php

/**
* check if the user is http digest authenticated
*
* @param array $users array of possible users (usernames as keys,
* password as values)
* @param string $realm realm (e.g. name of the site)
* @retval 0 authenticated
* @retval -1 user did not request authentication
* @retval -2 parts of the response are missing
* @retval -3 unknown username
* @retval -4 invalid password
*/

I try using = $data['response']
... AMm lost

Thanks

I use it, not sure that is totaly secure but it works !
I suppose the login need to be DIGEST !

<?php
if (empty($SERVER['PHPAUTH_DIGEST'])) {
} else {
$auth = $SERVER['PHPAUTH_DIGEST'];
}

$data = array();
preg_match("/username=\"([^\"]+)\"/i", $auth, $match);
if (isset($match[1])) {
	$data['username'] = $match[1];
} 


if (($data['username'] == "USER_NAME1") || ($data['username'] == "USER_NAME2")) { 

echo "<div id='username'>".$data['username']."<div>"; ?>
<script>
	$("html").addClass("logged"); 
</script>

But, it is possible to disconect an user ?
( in http method I dont think so )
