# 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/).
### Add library in a [composer.json](https://getcomposer.org/doc/01-basic-usage.md#composer-json-project-setup) file
```yaml
{
"minimum-stability":"dev",
"autoload": {
"psr-4": {
"Ethereum\\": "src/"
}
},
"repositories": [
{
"type": "git",
"url": "https://github.com/digitaldonkey/ethereum-php.git"
}
],
"require": {
"digitaldonkey/ethereum-php": "dev-master"
}
}
```
### Usage
```sh
composer require digitaldonkey/ethereum-php
```
This is the important part of [composer.json](https://github.com/digitaldonkey/ethereum/blob/8.x-1.x/composer.json) in [Drupal Ethereum Module](https://drupal.org/project/ethereum).
```php
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).
```php
$ContractMeta = json_decode(file_get_contents($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
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/digitaldonkey/ethereum-php/blob/master/UsingFilters.md) and [ethereum-php-eventlistener](https://github.com/digitaldonkey/ethereum-php-eventlistener).
### 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
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.
