This is the simplest form I found to do a Basic authorization with retries.

<?php

$valid_passwords
= array ("mario" => "carbonell");
$valid_users = array_keys($valid_passwords);

$user = $_SERVER['PHP_AUTH_USER'];
$pass = $_SERVER['PHP_AUTH_PW'];

$validated = (in_array($user, $valid_users)) && ($pass == $valid_passwords[$user]);

if (!
$validated) {
 
header('WWW-Authenticate: Basic realm="My Realm"');
 
header('HTTP/1.0 401 Unauthorized');
  die (
"Not authorized");
}

// If arrives here, is a valid user.
echo "<p>Welcome $user.</p>";
echo
"<p>Congratulation, you are into the system.</p>";

?>
