Quick Start Example

Call the Ethereum eth_protocolversion endpoint.

<?php

require_once('./vendor/autoload.php');

$Ethereum = new PHPBlock\Network\Ethereum\Client();

$Ethereum->ethProtocolVersion()
    ->then(function (string $version) {
        echo "The protocol version is: " . $version . "\n";
    });

$Ethereum->run();

Promises Example

You can chain calls and pass along additional information to next the link in the promise chain.

<?php

require_once('./vendor/autoload.php');

use PHPBlock\Network\Ethereum\Model\Gwei;
use PHPBlock\Network\Ethereum\Model\Transaction;
use PHPBlock\Network\Ethereum\Type\Hash32;
use PHPBlock\Network\Ethereum\Type\HexAddress;

use function PHPBlock\Helper\pass;

$Ethereum = new PHPBlock\Network\Ethereum\Client();
# Lightweight types for all data elements.
$value = new Gwei(Gwei::ethToGwei('.0001'));
$to = new HexAddress('0x579ACE666FBbb2cE728B5F335E69Dc7A2C8623D4');
$from = new HexAddress('0x268d5eBe19aF845c23E0Fd4290725E9679Cd1B7d');
$sendTransaction = Transaction::make($to, $from, $value);

$Ethereum->ethSendTransaction($sendTransaction)
    ->then(function (Hash32 $hash32) use ($Ethereum) {
        # Pass additional values easily similar to a tuple.
        return pass($Ethereum->ethGetTransactionByHash($hash32), $hash32);
    })->then(function (array $data) {
        [$receiveTransaction, $hash32] = $data;

        if ($receiveTransaction->hash == $hash32) {
            echo "The hashes match!";
        }
    });

$Ethereum->run();

Install

Get started quickly using Composer.

$ composer require phpblock/core

Testing

In order to run tests, you must first clone this repo and then install the dependencies through Composer:

$ composer install

You can then use the geth client or ganache-cli to test Ethereum RPC calls. You can also install the ganache client on Windows.

#Using geth (Ubuntu):
sudo add-apt-repository -y ppa:ethereum/ethereum
sudo apt-get update
sudo apt-get install ethereum

#Using geth (OS X & brew):
brew tap ethereum/ethereum
brew install ethereum
brew install ethereum --devel

#Using ganache-cli (npm)
npm install -g ganache-cli
ganache-cli

This project uses PHPUnit and PHPBench. To run the test suite, enter the project root and run:

$ composer run-script check
