README

Ethereum PHP allows you to interact with the Ethereum blockchain using PHP.
All you need to start is a running Ethereum node, with the JSON-RPC interface enabled.

Installation

Install this package using composer:

composer require ecourty/ethereum-php

Usage

Connecting to a Node

<?php

use EthereumPHP\Client\EthereumClient;

$client = new EthereumClient('http://localhost:8545');
// ...
$balance = $clent->getBalance('0x1234567890123456789012345678901234567890');
// ...
$latestBlock = $client->getLastBlock();
// ...

Using the EthereumConverter utility

EthereumPHP\Utils\EthereumConverter provides a set of methods to convert between different Ethereum units (wei, gwei, ether).

<?php

use EthereumPHP\Utils\EthereumConverter;

// ...
$weiAmount = 14500000789000000;
$etherAmount = EthereumConverter::weiToEther($weiAmount);
$gweiAmount = EthereumConverter::weiToGwei($weiAmount);

Remarks

Precise numbers such as WEI / GWEI / ETHER amounts are represented as strings instead of float or int to avoid precision loss.
The bcmath extension is needed for this library to work.
