It would seem that the location depends on the server in use:

  • $_SERVER["REMOTE_USER"] - CGI standard
  • $_SERVER["PHP_AUTH_USER"] - APACHE
  • $_SERVER["AUTH_USER"] - IIS

At my clients hoster $_SERVER['PHP_AUTH_USER'] and $_SERVER["HTTP_AUTHORIZATION"] were empty but $_SERVER["REMOTE_USER"] was set!

if ($_SERVER["REMOTE_USER"] == "admin")
    echo "Welcome, admin!";
else
    echo "Access denied";

Check what you have in $_SERVER (print_r($_SERVER)), sometimes $_SERVER['PHP_AUTH_USER'] is not available.

If you have value for $_SERVER["HTTP_AUTHORIZATION"], you may use:

if (isset($_SERVER["HTTP_AUTHORIZATION"]) {
        $auth = $_SERVER["HTTP_AUTHORIZATION"];
        $auth_array = explode(" ", $auth);
        $un_pw = explode(":", base64_decode($auth_array[1]));
        $un = $un_pw[0];
        $pw = $un_pw[1];
    }

Simply access this variable:

$_SERVER['PHP_AUTH_USER']
