Web3 PHP is a supercharged PHP API client that allows you to interact with a generic Ethereum RPC.

This project is a work-in-progress. Code and documentation are currently under development and are subject to change.

Get Started

Requires PHP 8.0+

First, install Web3 via the Composer package manager:

composer require web3-php/web3 dev-master

Then, interact with a local (web3-php/cli) or remote ethereum node:

use Web3\Web3;

$web3 = new Web3('http://127.0.0.1:8545');

$accounts = $web3->eth()->accounts(); // ['0x54a3259f4f693e4c1e9daa54eb116a0701edc403', ...]

Usage

Web3 Namespace

clientVersion

The clientVersion method returns the version of the current client.

$web3->clientVersion(); // TestRPC v2.13.2

sha3

The sha3 method hashes data using the Keccak-256 algorithm.

$web3->sha3('string'); // 0x348ab0847d053bb0150c1eb3470a71071d2967e20cf131b59dea3df9bf8f753e

Eth Namespace

accounts

The accounts method returns a list of addresses owned by this client.

$web3->eth()->accounts(); // ['0x54a3259f4f693e4c1e9daa54eb116a0701edc403', ...]

chainId

The chainId method returns the current chain id.

$web3->eth()->chainId(); // 1

gasPrice

The gasPrice method returns the current price of gas in wei.

$web3->eth()->gasPrice()->toEth(); // 0.00000002

getBalance

The getBalance method returns the balance of an address in wei.

$web3->eth()->getBalance('0x54a3259f4f693e4c1e9daa54eb116a0701edc403')->toEth(); // 100

getBlockTransactionCountByHash

The getBlockTransactionCountByHash method returns the number of transactions in a block by its hash.

$web3->eth()->getBlockTransactionCountByHash('0xd2a91777651a08b92d1d9fc701982c79da2249532cfe41a773a340978f96b5d1'); // 266

getTransactionByHash

The getTransactionByHash method returns information about a transaction by its hash.

$web3->eth()->getTransactionByHash('0x88df016429689c079f3b2f6ad39fa052532c56795b733da78a91ebe6a713944b');

getTransactionReceipt

The getTransactionReceipt method returns the receipt for a transaction by its hash.

$web3->eth()->getTransactionReceipt('0xbb3a336e3f823ec18197f1e13ee875700f08f03e2cab75f0d0b118dabb44cba0');

getUncleCountByBlockHash

The getUncleCountByBlockHash method returns the number of uncles in a block by its hash.

$web3->eth()->getUncleCountByBlockHash('0xd2a91777651a08b92d1d9fc701982c79da2249532cfe41a773a340978f96b5d1'); // 266

hashrate

The hashrate() method returns the number of hashes-per-second this node is mining at.

$web3->eth()->hashrate(); // '65'

isMining

The isMining() method determines if the client is mining new blocks.

$web3->eth()->isMining(); // true

blockNumber

The blockNumber() method returns the number (quantity) of the most recent block seen by this client.

$web3->eth()->blockNumber(); // '3220'

coinbase

The coinbase() method returns the Coinbase address of the client.

$web3->eth()->coinbase(); // '0xc014ba5ec014ba5ec014ba5ec014ba5ec014ba5e'

sendTransaction

The sendTransaction method creates, signs, and sends a new transaction to the network.

use Web3\ValueObjects\{Transaction, Wei};

$from = '0xc9257b94da7f8eb07537db73a4ad0603cd83aba4';
$to = '0x108d1089e4a737c0be63527a6e464564be948b03';
$value = Wei::fromEth('1');

$transaction = Transaction::between($from, $to)->withValue($value);

$web3->eth()->sendTransaction($transaction); // '0xa124a7de5177cf5cedd3c44e91d115d0011f915905fa36fb7c000a491fa536ee'

submitWork

The submitWork() method submits a proof-of-work solution, and returns a boolean based on the result.

$web3->eth()->submitWork($nonce, $proofOfWorkHash, $mixDigest); // true

Net Namespace

listening

The listening method determines if this client is listening for new network connections.

$web3->net()->listening(); // true

peerCount

The peerCount method returns the number of peers currently connected to this client.

$web3->net()->peerCount(); // 230

version

The version method returns the chain ID associated with the current network.

$web3->net()->version(); // 1637712995212
