From manual page: http://www.php.net/reserved.variables.server

I can confirm that $_SERVER['PHP_AUTH_USER'] and $_SERVER['PHP_AUTH_PW'] are populated when running lighttpd 1.4.26 with php/cgi 5.3.3 under fastcgi

Test script:
---------------
<?php
if (!isset($_SERVER['PHP_AUTH_USER'])) {
    header('WWW-Authenticate: Basic realm="My Realm"');
    header('HTTP/1.0 401 Unauthorized');
    echo 'Fine, be like that. See if I let you in.';
    exit;
} 
else {
    echo "<p>Hello {$_SERVER['PHP_AUTH_USER']}.</p>";
    echo "<p>You entered {$_SERVER['PHP_AUTH_PW']} as your password.</p>";
}
?>
