[PHP-WIN] HTTP-authentication

[Davy Obdam]

Hiya people,

I am building a admin page for a guestbook and i want more people to be
able to log in. I have made a table in the database called
user(gebruikers) wich keeps both a loginname(loginnaam) and password. I
have 2 users in this table right now. Now i ve a problem.. I can login
with the first person (myself), but i am unable to login with the second
user. Here is my code, i hope someone can help me..:)

<?php
function authenticate() 
{
        Header( "WWW-authenticate: basic realm=\"Gastenboek admin
pagina\"");
        Header( "HTTP/1.0 401 Unauthorized");
        echo   "U moet een geldinge loginnaam en wachtwoord invoeren om
deze functie te kunnen gebruiken!\n";
        exit;
}

function CheckPwd($user,$pass) 
{
        //Open database connectie
        include("scripts/db_connect.php");
        //Maak query
        $sql_query = "SELECT DISTINCT loginnaam, wachtwoord FROM
gebruikers WHERE loginnaam='$user'";
        //Verstuur query
        $sql_id = mysql_query($sql_query, $link) or die("error in
query");
        //Resultaat
        $sql = mysql_fetch_assoc($sql_id);
        $username =  $sql['loginnaam'];
        $password =  $sql['wachtwoord'];
        return ($user != $username || $pass != $password) ? false :
true;
        //Sluit database connectie
        mysql_free_result($sql_id);
        mysql_close($link);
}

if(!isset($PHP_AUTH_USER)) 
{
        authenticate();
}
elseif(!CheckPwd($PHP_AUTH_USER,$PHP_AUTH_PW)) 
{
        authenticate();
}

?>

Thanks already..
