Simple Bitcoin JSON-RPC client based on GuzzleHttp

Installation

Run php composer.phar require denpa/php-bitcoinrpc in your project directory or add following lines to composer.json

"require": {
    "denpa/php-bitcoinrpc": "^2.0"
}

and run php composer.phar update.

Requirements

PHP 7.0 or higher (should also work on 5.6, but this is unsupported)

Usage

Create new object with url as parameter

/**
 * Don't forget to include composer autoloader by uncommenting line below
 * if you're not already done it anywhere else in your project.
 **/
// require 'vendor/autoload.php';

use Denpa\Bitcoin\Client as BitcoinClient;

$bitcoind = new BitcoinClient('http://rpcuser:rpcpassword@localhost:8332/');

or use array to define your bitcoind settings

/**
 * Don't forget to include composer autoloader by uncommenting line below
 * if you're not already done it anywhere else in your project.
 **/
// require 'vendor/autoload.php';

use Denpa\Bitcoin\Client as BitcoinClient;

$bitcoind = new BitcoinClient([
    'scheme' => 'http',                 // optional, default http
    'host'   => 'localhost',            // optional, default localhost
    'port'   => 8332,                   // optional, default 8332
    'user'   => 'rpcuser',              // required
    'pass'   => 'rpcpassword',          // required
    'ca'     => '/etc/ssl/ca-cert.pem'  // optional, for use with https scheme
]);

Then call methods defined in Bitcoin Core API Documentation with magic:

/**
 * Get block info.
 */
$block = $bitcoind->getBlock('000000000019d6689c085ae165831e934ff763ae46a2a6c172b3f1b60a8ce26f');

$block('hash')->get();     // 000000000019d6689c085ae165831e934ff763ae46a2a6c172b3f1b60a8ce26f
$block['height'];          // 0 (array access)
$block->get('tx.0');       // 4a5e1e4baab89f3a32518a88c31bc87f618f76673e2cc77ab2127b7afdeda33b
$block->count('tx');       // 1
$block->has('version');    // key must exist and CAN NOT be null
$block->exists('version'); // key must exist and CAN be null
$block->contains(0);       // check if response contains value
$block->values();          // array of values
$block->keys();            // array of keys
$block->random(1, 'tx');   // random block txid
$block('tx')->random(2);   // two random block txid's
$block('tx')->first();     // txid of first transaction
$block('tx')->last();      // txid of last transaction

/**
 * Send transaction.
 */
$result = $bitcoind->sendToAddress('mmXgiR6KAhZCyQ8ndr2BCfEq1wNG2UnyG6', 0.1);
$txid = $result->get();

/**
 * Get transaction amount.
 */
$result = $bitcoind->listSinceBlock();
$totalAmount = $result->sum('transactions.*.amount');
$totalSatoshi = BitcoinClient::toSatoshi($totalAmount);

To send asynchronous request, add Async to method name:

use Denpa\Bitcoin\BitcoindResponse;

$promise = $bitcoind->getBlockAsync(
    '000000000019d6689c085ae165831e934ff763ae46a2a6c172b3f1b60a8ce26f',
    function (BitcoindResponse $success) {
        //
    },
    function (\Exception $exception) {
        //
    }
);

$promise->wait();

You can also send requests using request method:

/**
 * Get block info.
 */
$block = $bitcoind->request('getBlock', '000000000019d6689c085ae165831e934ff763ae46a2a6c172b3f1b60a8ce26f');

$block('hash');            // 000000000019d6689c085ae165831e934ff763ae46a2a6c172b3f1b60a8ce26f
$block['height'];          // 0 (array access)
$block->get('tx.0');       // 4a5e1e4baab89f3a32518a88c31bc87f618f76673e2cc77ab2127b7afdeda33b
$block->count('tx');       // 1
$block->has('version');    // key must exist and CAN NOT be null
$block->exists('version'); // key must exist and CAN be null
$block->contains(0);       // check if response contains value
$block->values();          // get response values
$block->keys();            // get response keys
$block->first('tx');       // get txid of the first transaction
$block->last('tx');        // get txid of the last transaction
$block->random(1, 'tx');   // get random txid

/**
 * Send transaction.
 */
$result = $bitcoind->request('sendtoaddress', ['mmXgiR6KAhZCyQ8ndr2BCfEq1wNG2UnyG6', 0.06]);
$txid = $result->get();

or requestAsync method for asynchronous calls:

use Denpa\Bitcoin\BitcoindResponse;

$promise = $bitcoind->requestAsync(
    'getBlock',
    '000000000019d6689c085ae165831e934ff763ae46a2a6c172b3f1b60a8ce26f',
    function (BitcoindResponse $success) {
        //
    },
    function (\Exception $exception) {
        //
    }
);

$promise->wait();
