http authentication not working?

Im tying to use the authentication code for the admin side to my site but i either im not writing the code correctly or i don't understand. probably both but wondered if you could help


The window with the authentication box comes up fine but i
basically don't know what username and password into the box. i thick its what is hardcoded in the code but it doesn't work - can you explain this to me am i doing something wrong. if i am how do i set the username and password so that it does work please. PHP:



PHP:
--------------------------------------------------------------------------------
PHP:

<?php # authentication.php
//This page handles the authentication for the admin pages

$authorized = FALSE; // Initialise a variable

//Check for authentication submission.
if ( ( isset($_SERVER['PHP_AUTH_USER']) AND isset($_SERVER['PHP_AUTH_PW'])) ) {

if ( ($_SERVER['PHP_AUTH_USER'] == 'CC006200') AND ($_SERVER['PHP_AUTH_PW'] == 'arsenal') ) { // if the correct values were entered ...
$authorized = TRUE;
}
}

//If they haven't been authorised, create the pop-up window.
if (!$authorized) {
header('WWW-Authenticate: Basic realm="Administration"');
header('HTTP/1.0 401 Unauthorized');
// For cancellations
}
?>



if this is not a good way for making an admin side to the site. Could someone explain to me how to make a good one, because all i have at the moment is access for normal users to register but would like some sort of admin side. - cheers

Works when I run it on my system. Maybe it's an apache setting gone wrong?
