<?php
$user = "username";
$pass = "password";
function httpauth(){
header('WWW-Authenticate: Basic realm="Login Required!"');
header('HTTP/1.0 401 Unauthorized');
echo 'Sorry you are not Authorized to be here!';
exit;
}
while($_SERVER['PHP_AUTH_USER'] != $user && $_SERVER['PHP_AUTH_PW'] != $pass){
httpauth();
}
?>
