A PHP library to consume data from the Open Rail Data initiative.

At present only Stomp (ActiveMQ) data for Network Rail is supported, but I will be adding support for Static Network Rail data (such as Schedule) and Stomp support for National Rail in the near future.

Installation

This is done via composer (packagist). Add the following to your composer.json file:

{
  "require": {
     "neilmcgibbon/php-open-rail-data": "0.1.0"
  }
}

Currently supported data feeds:

• Network Rail
  • ActiveMQ realtime feeds (via Stomp)
    • RTPPM - Real Time Passenger Performance Measurements
    • VSTP - Very Short Term Planning
    • Train Movements - Cancellations, Activations, Reinstatements, etc.
    • TD - Train Describer events

###Feeds not yet supported

• Network Rail

  • ActiveMQ realtime feeds (via Stomp)
    • TSR - Temporary Speed Restrictions
  • Static feeds (via HTTP)
    • Schedule - Schedule data
    • Reference Data - Reference data

• National Rail

  • all feed types

Usage:

Stomp - Network Rail events

Events are processed via the observer / event dispatcher pattern

Example:

To listen for Real Time Passenger Performance Measurements (RTPPM events), and then dump out the number of late trains on the "National Page" level:

Create the event listener

class ExampleEventListener
{

  public function onEventReceived(RtppmEvent $event)
  {
    echo "Received event. National page late trains count: ";
    echo $event->getNationalPage()->getPerformance()->getLateCount() . PHP_EOL;
  }
}

Create the connection and start listening

$connection = new \OpenRailData\NetworkRail\Services\Stomp\Connection(
  "network_rail_username",
  "network_rail_password"
);

// Create the Topic.
$topic = new OpenRailData\NetworkRail\Services\Stomp\Topics\Rtppm\RtppmTopic();

// Add our event listener to the topic
$topic->addListener(new ExampleEventListener());

// Subscribe to the topic by adding the topic to the connection
$connection->addTopic($topic);

// Start listening for events, the rest is handled by our event listener :-)
$connection->listen();

And thats it!
