Sim racing result reader for PHP
Clone or download


Build Status

Simresults is an open-source, object-oriented library built using PHP. It allows you to read out log files of a race game and transforms them to a simple data model to easily read out this data.

This project is the core of the website , which allows you to upload your race log files and transform them to a readable format. The uploaded results become saved and public, so visitors can share them with their fellow racers. An example result can be found at

The website is a service but also a demonstration of what is possible using this library. This library does not supply any HTML templates or whatsoever. Any 'implementation' is up to you within your own project and is not limited to any framework.

This project is created and maintained by Maurice van der Star

Supported games

Simresults supports a wide range of games:

  • rFactor
  • rFactor 2
  • Project Cars
  • Assetto Corsa
  • Automobilista
  • Game Stock Car 2012
  • Game Stock Car 2013
  • Game Stock Car Extreme
  • Formula Truck 2013
  • RACE
  • RACE 07
  • GTR
  • GTR2
  • GT Legends
  • RaceRoom Racing Experience
  • BMW M3 Challenge
  • F1 challenge 99-02

The following expansions of RACE (07) should work too:

  • Race: Caterham expansion
  • GTR Evolution
  • Crowne Plaza
  • STCC - The Game
  • STCC 2 - The Game
  • RACE On
  • Raceroom - The Game
  • Raceroom - The Game 2
  • Formula Raceroom
  • GT Power
  • WTCC 2010
  • Retro
  • Race Injection
  • Volvo - The Game

Please note that Formula Truck will be reported as as a rFactor game.

Results from F1 challenge and GTR might miss laps.

Results from Assetto Corsa (race_out.json) and Raceroom might only contain 1 lap.


  • Can read out a full session consisting of the following information: Game, Server, Settings, Track, Participants/Drivers including swaps, Vehicle, Compound choice, Chats, Laps/Sectors, Fuel usage, Pit info, Penalties and Incidents
  • Offers extra methods to get specific data, e.g. getBestLap() and getBestLapBySector(<int>)
  • Offers a Helper class to sort laps by time and format times to human readable format (h:i:s.u)
  • Caches heavy methods like getLapsSortedBySector(<int>). This is very useful with endurance results that have 200+ laps
  • The API is unittested

rFactor reader


  • Supports rFactor and rFactor 2. Also works for other rFactor powered games: Automobilista, Game Stock Car 2012, Game Stock Car 2013 and Formula Truck 2013
  • Detects and fixes position data (sometimes log files report complete wrong positions due to lag/bugs)
  • Detects human and AI players using their aids (sometimes log files report wrong player state)

Project Cars Server reader


Assetto Corsa reader


  • Limited data. Use server logs if possible.

Assetto Corsa Server reader


Assetto Corsa Server reader JSON


RaceRoom Server reader


  • Limited data. Only contains the best lap of drivers.

RACE 07 reader


  • Also works for the following games: RACE, GTR, GTR2, GT Legends, BMW M3 Challenge, F1 challenge 99-02 and all expansions of these games
  • Checks and fixes log variations like non-zero based laps and missing lap data


  • PHP 5.3
  • Composer (for easy installing and autoloading)

Installation and example

Simresults can be installed and autoloaded using composer. But ofcourse it will work with any PSR-0 autoloader.

Example for Linux/OSX

Install composer:

curl -s | php

Create file composer.json:

    "require": {

Run composer install

./composer.phar install

Create index.php:


// Load code

// Path to the result source file
$file = realpath(dirname(__FILE__)

// Get a reader using the source file
$reader = \Simresults\Data_Reader::factory($file);

// Get the session
$session = $reader->getSession();

// Get participants sorted by their position
$participants = $session->getParticipants();

// Get the driver name of the second participant
$driver_name = $participants[1]->getDriver()->getName();

// Get the best lap of the second participant
$best_lap = $participants[1]->getBestLap();

// Get the best lap of the session
$session_best_lap = $session->getBestLap();

// Format the gap between the two laps
$helper = new \Simresults\Helper;
$best_lap_gap = $helper->formatTime($session_best_lap->getGap($best_lap));
echo $best_lap_gap;

Run server

 php -S localhost:8000

Open http://localhost:8000 and all should work!

For further usage please read the classes code within the lib folder. They are carefully documented.

Known issues


Some classes like Participant do heavy caching. So changing any value after calling sorting methods will be pointless. There are no cache invalidate methods (yet). Most likely they will never be needed as there's no use case you actually would want to change values after reading out all data.

When writing a reader. NEVER call methods like getVehicle() on Participant (which uses cached methods). Re-use your own created objects (like $vehicle) within the reading to prevent any early invalid cache. Do this for all type of objects.

Laps missing

Logs tend to miss lap data on all games. Check the logs.

Marked as RACE session while it's not

The Race 07 reader detects qualify if all drivers are DNF. There's no session type in these log files. This detection might be false in some cases.

Date is not right of session

GTR, GTL, F1 challenge don't have a timestamp or timezone information. So dates are created using the default timezone.


The project is designed to be extended with new features and game support. Feel free to fork Simresults on GitHub and submit a pull request!

The project is tested using PHPUnit and phpspec. If you offer any changes, make sure all your new additions are tested.

Running simresults tests

To run the tests, use the following command:

./vendor/bin/phpspec run
