casper-php-sdk

The PHP SDK allows developers to interact with the Casper Network using PHP. This page covers different examples of using the SDK.

Install

composer require make-software/casper-php-sdk

IMPORTANT

For using Secp256K1 keys you need to install and enable secp256k1-php extension:

git clone git@github.com:bitcoin-core/secp256k1 && \
    cd secp256k1 && \
    ./autogen.sh && \
    ./configure --enable-experimental --enable-module-{ecdh,recovery} && \
    make && sudo make install && \
    cd ../

git clone git@github.com:Bit-Wasp/secp256k1-php && \
    cd secp256k1-php/secp256k1 && \
    phpize && \ 
    ./configure --with-secp256k1 && \  
    make && sudo make install && \
    cd ../../

Enable extension by adding the following line to your php.ini file

extension=secp256k1.so

Usage

Creating RpcClient

Create RpcClient by passing node url and headers (optional) to constructor

$nodeUrl = 'http://127.0.0.1:7777';
$headers = array('Authorization' => 'Bearer 6ae6c8b31f09df244019ffef60c274e4'); // Optional

$client = new Casper\Rpc\RpcClient($nodeUrl, $headers);

RPC call examples

You can find all RpcClient methods on the RpcClientAPI page. Here you can see a several of examples of using RpcClient. All examples below are supposed to be ran against the Testnet

Get deploy by deploy hash

$deploy = $client->getDeploy('fa815fc43c38da30f6ab4e5a6c8a1b31f09df2bf4b344019ffef60c1270d4e49');

$deployHeader = $deploy->getHeader();
$creationTime = $deployHeader->getTimestamp();

Get auction state information

$auctionState = $client->getAuctionState();

$stateRootHash = $auctionState->getStateRootHash();
$blockHeight = $auctionState->getBlockHeight();

Get peers from the network

$peers = $client->getPeers();

foreach ($peers as $peer) {
    ...
}

Get the latest block information

$latestBlock = $client->getLatestBlock();
$latestBlockHash = $latestBlock->getHash();

Testing

Run the following command from the project directory.

Replace http://127.0.0.1:7777 by the any Testnet node url before running

export CASPER_PHP_SDK_TEST_NODE_URL="http://127.0.0.1:7777" && php vendor/bin/phpunit tests
