Ethereum-PHP
============

[](#ethereum-php)

is a typed PHP-7.1+ interface to [Ethereum JSON-RPC API](https://github.com/ethereum/wiki/wiki/JSON-RPC).

Check out the latest [API documentation](http://ethereum-php.org/dev/).

### Usage

[](#usage)

```
composer require delboy1978uk/ethereum-php
```

This is the important part of [composer.json](https://github.com/delboy1978uk/ethereum/blob/8.x-1.x/composer.json) in [Drupal Ethereum Module](https://drupal.org/project/ethereum).

```
require __DIR__ . '/vendor/autoload.php';
use Ethereum\Ethereum;

try {
	// Connect to Ganache
    $eth = new Ethereum('http://127.0.0.1:7545');
    // Should return Int 63
    echo $eth->eth_protocolVersion()->val();
}
catch (\Exception $exception) {
    die ("Unable to connect.");
}
```

**Calling Contracts**

You can call (unpayed) functions in smart contracts easily.

The json file "$fileName" used is what you get when you compile a contract with [Truffle](truffleframework.com).

```
$ContractMeta = json_decode(file_get_contents($fileName));
$contract = new SmartContract(
  $ContractMeta->abi,
  $ContractMeta->networks->{NETWORK_ID}->address,
  new Ethereum(SERVER_URL)
);
$someBytes = new EthBytes('34537ce3a455db6b')
$x = $contract->myContractMethod();
echo $x->val()
```

You can also run tests at smart contracts, check out EthTestClient.

### Event listening and handling

[](#event-listening-and-handling)

You can use Ethereum-PHP to watch changed on your smart contracts or index a Blockchain block by block. gs

See [UsingFilters](https://github.com/delboy1978uk/ethereum-php/blob/master/UsingFilters.md) and [ethereum-php-eventlistener](https://github.com/delboy1978uk/ethereum-php-eventlistener).

### Limitations

[](#limitations)

Currently not all datatypes are supported.

This library is read-only for now. This means you can retrieve information stored in Ethereum Blockchain.

To *write* to the blockchain you need a to sign transactions with a private key which is not supported yet.

### Documentation

[](#documentation)

The API documentation is available at [ethereum-php.org](http://ethereum-php.org/).

For reference see the [Ethereum RPC documentation](https://github.com/ethereum/wiki/wiki/JSON-RPC) and for data encoding [RLP dcumentation](https://github.com/ethereum/wiki/wiki/RLP) in [Ethereum Wiki](https://github.com/ethereum/wiki).

There is also a more readable [Ethereum Frontier Guide](http://ethereum.gitbooks.io/frontier-guide/content/rpc.html) version.
