gzbruno, 

First, I strongly recommend that you drop that 2009 file because it will be deprecated, and start using the 2016 version because it works with SceneGraph.

Second, yes, I have php files to:

1. generate: take the token from the roku device (token = serial number + model number) and generate a six-digit (alphanumeric) code to display on the roku device screen;  return as json code, token and update
2. authenticate: take the token, generate a 12-digit alphanumeric code for the oauth_token which is written to device registry and database; return as json token, linked status, and oauth_token 
3. activate: take user_number and that 6-digit code from generate.php as input from a html form; check a subscriber list that the user_number is a subscriber (there's a limit of 2 devices per subscriber account) and that the 6-digit code matches

...and then success! If the subscriber wasn't linked before, she is now; if she was, she goes right to the content scene.

How's your php? Here's the first one, generate.php

<?php header('content-type: application/json; charset=utf-8');
    // GENERATE

if (isset($_GET["token"])) {
 require_once "../../settings.php";
    require_once "../../utils.php";
 
    $token = $_GET["token"];
    $update_gen = "yes";

// First, check if it has an agent associated with it... 0 or 1 is okay, 2 is a too many

    $mysqli = new mysqli($db_host, $db_user, $db_pass, $db_name);
    if ($mysqli->connect_error) {
        die("Connection failed: " . $mysqli->connect_error);
    }
    $query = "SELECT linked FROM `<my_database>` WHERE token = ?";
    if ($stmt = $mysqli->prepare($query)) {
        $stmt->bind_param('s', $token);
        $stmt->execute();
        $stmt->bind_result($linked);
        $stmt->fetch();
        $stmt->close();
    } else {
        echo "Errormessage1: " . $mysqli->error;
    }   
    $mysqli->close();


// Second, if linked = 'yes', 

    if ($linked) {
        //it's linked; read value for code
        $mysqli = new mysqli($db_host, $db_user, $db_pass, $db_name);
        if ($mysqli->connect_error) {
            die("Connection failed: " . $mysqli->connect_error);
        }
        $query = "SELECT code FROM `<my_database>` WHERE token = ?";
        if ($stmt = $mysqli->prepare($query)){
            $stmt->bind_param('s', $token);
            $stmt->execute();
            $stmt->bind_result($code);
            $stmt->fetch();           
            $stmt->close();  
            $update_gen = "no";
        } else {
            die("Errormessage2: ");
        }    
        
    } else {
        // a new entry!!! device not linked yet
        // generate code and write token, code, update_gen and linked to db
        $code = makeCode(6);
        $linked = "no";
        $mysqli = new mysqli($db_host, $db_user, $db_pass, $db_name);
        if ($mysqli->connect_error) {
            die("Connection failed: " . $mysqli->connect_error);
        }
        $query = "INSERT INTO `<my_database>` (token, code, update_gen, linked) VALUES (?, ?, ?, ?) ";
        if ($stmt = $mysqli->prepare($query)){
            $stmt->bind_param('ssss',  $token, $code, $update_gen, $linked);
            $stmt->execute();
            $stmt->close();
        } else {
            die("Errormessage3: ". $mysqli->error);
        }
    }

    $mysqli->close();

    
    $d = array("code" => $code, "deviceToken" => $token, "update" => $update_gen);
 $result = json_encode($d);
 
    echo $result;

}
?>

settings.php has the host, user, password and database names; utils.php has some functions to sanitize input and generate codes, like makeCode(length) below

// generate a random base36 code; length is argument
function makeCode($code_length){
    $text = "";
    $possible = "ABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789"; // base36
    
    for( $i=0; $i < $code_length; $i++ ){
        $randomness = rand(0,35);
        $text = $text . $possible{$randomness};
    }
    
    return $text;
  }

Let me know if this will work for you. It may not be the best or most efficient php, but it works (kinda like php itself).

Good luck.
