PHP has a function for this as well. You use the header() thing hold on I think I saw a function to do this.

Here is what you could put at the top of your webpage:

PHP Code:

if (empty($PHP_AUTH_USER))
{
    authenticate($realm,$errmsg,"header");
}
else
{
    $query = "SELECT username FROM author WHERE password = md5(lower('$PHP_AUTH_PW')) and username = lower('$PHP_AUTH_USER')";
    $result = mysql_query($query);
    if ($result)
    {
        list($valid_user) = mysql_fetch_row($result);
    }
    if (!$result || empty($valid_user))
    {
        authenticate($realm, $errmsg, "query");
    }
} 


The authenticate function would look something like this:

PHP Code:

function authenticate ($realm="Secure Area"
    ,$errmsg="Please enter a username and password"
)
{
    Header("WWW-Authenticate: Basic realm=\"$realm\"");
    Header("HTTP/1.0 401 Unauthorized");
    die($errmsg);
}
