README

This project is used to interact with a headless bitcoin program called bitcoind. It also contains various utility classes for working with Bitcoin as a PHP Developer.

Installation

You can install this library by using Composer. You can also view more info about this on Packagist.

composer require nbobtc/bitcoind-php

Usage

To use the project you need to just create a new instance of the class.

<?php

require __DIR__ . '/vendor/autoload.php';

$command = new \Nbobtc\Command\Command('getinfo');
$client  = new \Nbobtc\Http\Client('https://username:password@localhost:18332');

/** @var \Nbobtc\Http\Message\Response */
$response = $client->sendCommand($command);

/** @var string */
$contents = $response->getBody()->getContents();
echo $contents;

You are able to get the Request and Response objects back from the client with the correct getters: getRequest() and getResponse().

You can also parse the response however you wish to do so since the result is returned to you as a string. See below for some ideas!

Commands

Commands are created in such a way that this will support any future updates the Bitcoin API by providing you with an easy class that sets all the required information.

You are able to pass into the object the method and the parameters that are required. Here are a few examples:

// No Parameters
$command = new Command('getinfo');

// One Parameter
$command = new Command('getblock', '000000000019d6689c085ae165831e934ff763ae46a2a6c172b3f1b60a8ce26f');

// Multiple Parameters
$command = new Command('sendfrom', array('fromaccount', 'tobitcoinaddress', 'amount'));

The second argument MUST be in the same order as on the Bitcoin API wiki page. There is no need to assign the values any keys.

Parameters

Parameters are the second argument when creating a new Command. This argument can either be a string OR an array. For example, both of these are valid.

$command = new Command('getblock', array('000000000019d6689c085ae165831e934ff763ae46a2a6c172b3f1b60a8ce26f'));
$command = new Command('getblock', '000000000019d6689c085ae165831e934ff763ae46a2a6c172b3f1b60a8ce26f');

Most commands in the Bitcoin API take one parameter. If it takes MORE than one, you must pass the parameters in as an array in the ORDER you find them on that page.

Extending Commands

If, for any reason, you need to extend a command, it MUST implement CommandInterface. You can find documentation within the interface on how to implement this.

Drivers

Drivers are used by the ClientInterface for connecting to a bitcoind service and sending Requests. The return a Response. If you need to implement a new driver take a look at the DriverInterface.

cURL Driver

This is used by default and allows you a lot of options for customizing it to your needs.

You can set various cURL Options by passing them into the function addCurlOption($option, $value).

Here's an example of how to configure and use the driver.

$driver = new \Nbobtc\Http\Driver\CurlDriver();
$driver
    ->addCurlOption(CURLOPT_VERBOSE, true)
    ->addCurlOption(CURLOPT_STDERR, '/var/logs/curl.err');

$client = new \Nbobtc\Http\Client('https://username:password@localhost:18332');
$client->withDriver($driver);

Feel free to take a look at the CurlDriver source code.

Cookbook

How to enable a Keep-Alive ie Persistent Connection

This example shows how you are able to set the client up to Persistent Connection.

$client = new \Nbobtc\Http\Client('https://username:password@localhost:18332');
$client->getRequest()->withHeader('Connection', 'Keep-Alive');

How to set a CA Cert

This library provides some wonderful flexibility that will allow you to configure the client to use your own CA Cert.

$driver = new \Nbobtc\Http\Driver\CurlDriver();
$driver->addCurlOption(CURLOPT_CAINFO, '/path/to/cert');

$client = new \Nbobtc\Http\Client('https://username:password@localhost:18332');
$client->withDriver($driver);

How to Convert Output to an Array

Some like the arrays

$response = $client->sendCommand($command);
$output   = json_decode($response->getBody()->getContents(), true);

How to Convert Output to a stdClass object

Some like the objects

$response = $client->sendCommand($command);
$output   = json_decode($response->getBody()->getContents());

Testing

All testing is done using PHPUnit. You should be able to run phpunit in the root directory of this project (the directory where phpunit.xml.dist is located) and the tests will run.

If submitting a pull request or working on this library, please make sure that the tests will pass.
