PHP Transmission API

This library provides an interface to the Transmission bit-torrent downloader. It provides means to get and remove torrents from the downloader as well as adding new torrents to the download queue.

Installation

Installation is easy using Composer:

{
    "require": {
        "kleiram/transmission-php": "dev-master"
    }
}

Usage

Using the library is as easy as installing it:

<?php
use Transmission\Transmission;

$transmission = new Transmission();

// Getting all the torrents currently in the download queue
$torrents = $transmission->all();

// Getting a specific torrent from the download queue
$torrent = $transmission->get(1);

// (you can also get a torrent by the hash of the torrent)
$torrent = $transmission->get(/* torrent hash */);

// Adding a torrent to the download queue
$torrent = $transmission->add(/* path to torrent */);

// Removing a torrent from the download queue
$torrent = $transmission->get(1);
$transmission->remove($torrent);

// Or if you want to delete all local data too
$transmission->remove($torrent, true);

// You can also get the Trackers that the torrent currently uses
// These are instances of the Transmission\Model\Tracker class
$trackers = $torrent->getTrackers();

// You can also get the Trackers statistics and info that the torrent currently has
// These are instances of the Transmission\Model\trackerStats class
$trackerStats = $torrent->getTrackerStats();

// To get the start date/time of the torrent in UNIX Timestamp format
$startTime = $torrent -> getStartDate();

// To get the number of peers connected
$connectedPeers = $torrent -> getPeersConnected();

// Getting the files downloaded by the torrent are available too
// These are instances of Transmission\Model\File
$files = $torrent->getFiles();

// You can start, stop, verify the torrent and ask the tracker for
// more peers to connect to
$transmission->stop($torrent);
$transmission->start($torrent);
$transmission->start($torrent, true); // Pass true if you want to start the torrent immediatly
$transmission->verify($torrent);
$transmission->reannounce($torrent);

To find out which information is contained by the torrent, check Transmission\Model\Torrent.

By default, the library will try to connect to localhost:9091. If you want to connect to another host or post you can pass those to the constructor of the Transmission class:

<?php
use Transmission\Transmission;

$transmission = new Transmission('example.com', 33);

$torrents = $transmission->all();
$torrent  = $transmission->get(1);
$torrent  = $transmission->add(/* path to torrent */);

// When you already have a torrent, you don't have to pass the client again
$torrent->delete();

It is also possible to pass the torrent data directly instead of using a file but the metadata must be base64-encoded:

<?php
$torrent = $transmission->add(/* base64-encoded metainfo */, true);

If the Transmission server is secured with a username and password you can authenticate using the Client class:

<?php
use Transmission\Client;
use Transmission\Transmission;

$client = new Client();
$client->authenticate('username', 'password');
$transmission = new Transmission();
$transmission->setClient($client);

Additionally, you can control the actual Transmission setting. This means you can modify the global download limit or change the download directory:

<?php
use Transmission\Transmission;

$transmission = new Transmission();
$session = $transmission->getSession();

$session->setDownloadDir('/home/foo/downloads/complete');
$session->setIncompleteDir('/home/foo/downloads/incomplete');
$session->setIncompleteDirEnabled(true);
$session->save();

Testing

Testing is done using PHPUnit. To test the application, you have to install the dependencies using Composer before running the tests:

$ curl -s https://getcomposer.org/installer | php
$ php composer.phar install
$ phpunit --coverage-text

Integration into frameworks

Currently, there's a Symfony bundle in development which allows you to easily use this library within Symfony.
