Getting started

Ethereum-PHP is a typed PHP-7 interface to Ethereum JSON-RPC API.

Check out the latest API documentation.

Install the library in a composer file

{
  "repositories": [
    {
      "type": "git",
      "url": "https://github.com/digitaldonkey/ethereum-php.git"
    }
  ],
  "require": {
    "digitaldonkey/ethereum-php": "dev-master",
  }
}

This is the important part of composer.json in Drupal Ethereum Module.

Extend

use Ethereum\EthereumClient;
use Ethereum\Ethereum_Message;
use Ethereum\Ethereum_Transaction;

class EthereumController extends ControllerBase {

  public $client;

  public function __construct($host = FALSE) {
    if (!$host) {
      $host = 'http://localhost:8445'
    }
    $this->client = new EthereumClient($host);
  }

}

Use

    try {
      $eth = new EthereumController();
      echo $eth->client->eth_protocolVersion();
    }
    catch (\Exception $exception) {
      die ("Unable to connect.");
    }
