# 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](https://developers.eos.io/eosio-nodeos/reference) but 
beware that some of the newer methods are missing.
Wallet RPC APIs are implemented as [v1.1.0 of RPC API reference](https://developers.eos.io/eosio-nodeos/v1.1.0/reference).
Also, some of the examples in those docs use outdated syntax.

## Installing

```php
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:

```php
$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.

## Chain APIs

## EOS Wrapper APIs

### Prerequisites

Need to set wallet name and password

```php
$eos->setWalletInfo("testwallet", "PW5Jb8RAZP6CBjjMLPser3T8i8k9hZXZkMBJ8kb1p6f6hAg2n68jY");
```

### Push Transaction

Push a transaction

```php
echo $eos->pushTransaction(
    [
        [
            "account" => "eosio.token",
            "name" => "transfer",
            "authorization" => [
                [

                "memo" => "memo"
            ]
        ]
    ]
);
```

### Make Transaction

Make a transaction (useful for pushTransactions)

```php
$trx = $eos->makeTransaction(
    [
        [
            "account" => "eosio.token",
            "name" => "transfer",
            "authorization" => [

                "from" => "user",
                "to" => "tester",
                "quantity" => "1.0000 EOS",

                ]
            ]
        )
    ]
);
foreach ($trx_ids as $key => $value) {
    echo $trx_ids[$key]['transaction_id'] . PHP_EOL;
}
```

### Push Action

Push an action

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

### Transfer

Transfers token

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

### Create Key Pair

Creates a key pair and returns

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

## Tests

To run the test suites, simply execute:

```php
vendor/bin/phpunit
```

If you wanna get fancy and check code coverage:

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

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

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

## Contributing

All contributions are welcome! Just fire up a PR, make sure your code style is PSR-2 compliant:
