Good day.
Sorry for my english.
This example shows programming "LOGIN", "LOGOUT" and "RE-LOGIN".
This script must use in the protected pages.
For work this script the browser address string must be following:
"http://localhost/admin/?login" - for Login,
"http://localhost/admin/?logout" - for Logout,
"http://localhost/admin/?logout&login" - for Re-Login.
<?php
session_start
();

$authorized = false;

# LOGOUT
if (isset($_GET['logout']) && !isset($_GET["login"]) && isset($_SESSION['auth']))
{
   
$_SESSION = array();
    unset(
$_COOKIE[session_name()]);
   
session_destroy();
    echo
"logging out...";
}

# checkup login and password
if (isset($_SERVER['PHP_AUTH_USER']) && isset($_SERVER['PHP_AUTH_PW']))
{
   
$user = 'test';
   
$pass = 'test';
    if ((
$user == $_SERVER['PHP_AUTH_USER']) && ($pass == ($_SERVER['PHP_AUTH_PW'])) && isset($_SESSION['auth']))
    {
   
$authorized = true;
    }
}

# login
if (isset($_GET["login"]) && !$authorized ||
# relogin
   
isset($_GET["login"]) && isset($_GET["logout"]) && !isset($_SESSION['reauth']))
{
   
header('WWW-Authenticate: Basic Realm="Login please"');
   
header('HTTP/1.0 401 Unauthorized');
   
$_SESSION['auth'] = true;
   
$_SESSION['reauth'] = true;
    echo
"Login now or forever hold your clicks...";
    exit;
}
$_SESSION['reauth'] = null;
?>
<h1>you have <? echo ($authorized) ? (isset($_GET["login"]) && isset($_GET["logout"]) ? 're' : '') : 'not '; ?>logged!</h1>
