That’s all it takes to have the little box show up and demand a username and password. Now all you have to do is check the submitted username and password against the correct ones. Simply check the $_SERVER[‘PHP_AUTH_USER’] and $_SERVER[‘PHP_AUTH_PW’] global variables.

<?php
$authenticate = false;
if (isset($_SERVER['PHP_AUTH_USER']) && isset($_SERVER['PHP_AUTH_PW'])) {
$name = $_SERVER['PHP_AUTH_USER'];
$pass = $_SERVER['PHP_AUTH_PW'];
if ($name == 'user' && $pass == 'pass') {
$authenticate = true;
}
}
if ($authenticate == false) {
header('WWW-Authenticate: Basic realm="Restricted Page Enter Details To Continue"');
header('HTTP/1.0 401 Unauthorized');
echo "Authentication Failed Refresh To Do It Again";
} else {
