Well, just check them against the database (mysql?):
<?php
$verified =3D false;
if(isset($_SERVER['PHP_AUTH_USER'])){
$user =3D mysql_real_escape_string($_SERVER['PHP_AUTH_USER']);
$result =3D mysql_query("SELECT `passwd` FROM `tablename` WHERE `user` =
=3D =
'$user'");
if(mysql_num_rows($result) =3D=3D 1){
$row =3D mysql_fetch_assoc($result);
if($row['passwd']=3D=3D$_SERVER['PHP_PW']) $verified =3D true;
}
}
if(!$verfied){
header('WWW-Authenticate: Basic realm=3D"My Realm"');
header('HTTP/1.0 401 Unauthorized');
echo 'Text to send if user hits Cancel button';
exit;
}
?>
