Hacky FTTC Check Script

fttc-check.php

<?php
// Change me
const ADDRESS_ID  = 'Gold|StringOfAlphas|MY|HouseNumber'; // You can find your Address ID using this: https://gist.github.com/TomNomNom/7875919
const TO_EMAIL = 'me@example.com';
const FROM_EMAIL = 'server@example.com';


// Don't change me
const SERVICE_URL = 'http://www.productsandservices.bt.com/consumerProducts/v1/productAvailability.do';

$query = http_build_query(array(
  'addressId' => ADDRESS_ID,
  'format'    => 'json'
));

$r = file_get_contents(SERVICE_URL.'?'.$query);
$s = json_decode($r);

if (!$s){
  sendMail("FTTC Check Script Failed", "Failed to parse JSON");
  exit(1);
}

$message = 
  "Exchange name: {$s->exchangeName}\r\n".
  "Service types available: \r\n";

$infinityAvailable = false;
foreach ($s->serviceLineTypes as $i => $lineType){
  if ($lineType->infinity){
    $infinityAvailable = true;
  }
  $message .= "  #{$i} {$lineType->serviceLineType}\r\n";
}

if ($infinityAvailable){
  sendMail("FTTC Available!", $message);
} else {
  sendMail("FTTC Not Available", $message);
}

exit(0);

function sendMail($subject, $body){

  mail(TO_EMAIL, $subject, $body, $headers);

You might want to factor in readyDate or risk getting your hopes up with a false positive, like I did :D
