Getting started

<?php
require 'vendor/autoload.php';

use kak\CurrencyConverter\Converter;

$converter = new Converter;

var_dump($converter->get('USD', ['RUB', 'KZT']));

// caching currency
$cache = new Cache;
$converter = new Converter($cacheAdapter, [
  Converter::ADAPTER_OPEN_EXCHANGE_RATES => [
      'apiKey' => $_ENV['OPEN_EXCHANGE_RATES_KEY'] ?? '',
  ]
]);



echo "result 1 USD in RUB  \n";
var_dump($converter->get('USD', ['RUB'], 1, false, [Converter::ADAPTER_OPEN_EXCHANGE_RATES ]));
echo "result 2 RUB in USD  \n";
var_dump($converter->get('RUB', ['USD'], 2 , true, [Converter::ADAPTER_OPEN_EXCHANGE_RATES]));
var_dump($converter->getRates('RUB', [], false, [Converter::ADAPTER_OPEN_EXCHANGE_RATES]));

namespace app\helpers\CacheAdapter;
use yii\base\Object;
use Yii;

class Cache Extends Object implements \kak\CurrencyConverter\ICache
{
    public function contains($id)
    {
       return Yii::$app->cache->get($id);
    }
