The PHP SDK for the EOS RPC API

A PHP wrapper for the EOS Chain/Wallet RPC API.

Background

You can check out the RPC API reference but beware that some of the newer methods are missing. Wallet RPC APIs are implemented as v1.1.0 of RPC API reference. Also, some of the examples in those docs use outdated syntax.

Installing

composer require manamine/php-eos-rpc-sdk

Configuration

Create a dotenv .env file in the project root, with your favorite RPC API host and KEOSD. You can use .env.example as a template:

cp .env.example .env

Usage

There is a shiny factory method to auto instantiate all dependencies:

$api = (new ChainFactory)->api();
$walapi = (new WalletFactory)->api();
$eos = (new EosRpc($api, $walapi));

Examples

To get you started, there is a simple example runner which covers all API commands.

Just run this via cli to see example output for all commands:

cd examples
php chain.php
php wallet.php
php eosrpc.php

API Methods

Almost Chain/Wallet API methods are covered.

Push Action

Push an action

echo $eos->pushAction("eosio", "buyram", ["payer"=>"tester","receiver"=>"tester","quant"=>"1.0000 EOS"], ["actor"=>"tester","permission"=>"active"]);

Transfer

Transfers token

echo $eos->transfer("user", "tester", "1.0000 EOS", "memo");

Create Key Pair

Creates a key pair and returns

$keyPair = $eos->createKeyPair("K1");
echo "$keyPair[0], $keyPair[1]";

Tests

To run the test suites, simply execute:

vendor/bin/phpunit

If you wanna get fancy and check code coverage:

vendor/bin/phpunit --coverage-html tests/coverage

If you're really bored, you might wanna run some static analysis:

vendor/bin/phpmetrics --report-html="tests/static" .
