web3.php

A php interface for interacting with the Ethereum blockchain and ecosystem.

Install

Set minimum stability to dev

"minimum-stability": "dev"

Then

composer require sc0vu/web3.php dev-master

Or you can add this line in composer.json

"sc0vu/web3.php": "dev-master"

Usage

New instance

use Web3\Web3;

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

Using provider

use Web3\Web3;
use Web3\Providers\HttpProvider;
use Web3\RequestManagers\HttpRequestManager;

$web3 = new Web3(new HttpProvider(new HttpRequestManager('http://localhost:8545')));

You can use callback to each rpc call:

$web3->clientVersion(function ($err, $version) {
    if ($err !== null) {
        // do something
        return;
    }
    if (isset($client->result)) {
        echo 'Client version: ' . $version->result;
    } else {
        // do something rpc error
    }
});

Eth

use Web3\Web3;

$web3 = new Web3('http://localhost:8545');
$eth = $web3->eth;

Or

use Web3\Eth;

$eth = new Eth('http://localhost:8545');

Net

use Web3\Web3;

$web3 = new Web3('http://localhost:8545');
$net = $web3->net;

Or

use Web3\Net;

$net = new Net('http://localhost:8545');

Batch

web3

$web3->batch(true);
$web3->clientVersion();
$web3->hash('0x1234');
$web3->execute(function ($err, $data) {
    if ($err !== null) {
        // do something
        return;
    }
    // do something
});

eth

$eth->batch(true);
$eth->protocolVersion();
$eth->syncing();

$eth->provider->execute(function ($err, $data) {
    if ($err !== null) {
        // do something
        return;
    }
    // do something
});

net

$net->batch(true);
$net->version();
$net->listening();

$net->provider->execute(function ($err, $data) {
    if ($err !== null) {
        // do something
        return;
    }
    // do something
});

Contract

use Web3\Contract;

$contract = new Contract('http://localhost:8545', $abi);

// deploy contract
$contract->bytecode($bytecode)->new($params, $callback);

// call contract function
$contract->at($contractAddress)->call($functionName, $params, $callback);

// change function state
$contract->at($contractAddress)->send($functionName, $params, $callback);

Examples

To run examples, you need to run ethereum blockchain local (testrpc).

If you are using docker as development machain, you can try ethdock to run local ethereum blockchain, just simply run docker-compose up -d testrpc and expose the 8545 port.

API

Todo.
