## Install

Lets begin by installing the library by Composer:

``` bash
$ composer require jimmerioles/bitcoin-currency-converter-php
```

## Usage

#### You can then convert Bitcoin to any currency (ISO 4217 fiat or crypto) by:

``` php
use Jimmerioles\BitcoinCurrencyConverter\Converter;

$convert = new Converter;              // uses Coinbase as default provider
echo $convert->toCurrency('USD', 0.5); // 2000.00
echo $convert->toCurrency('LTC', 0.5); // 10.12345678
```

or you can use the helper function for convenience:

``` php
// uses Coinbase as default provider
echo to_currency('USD', 0.5); // 2000.00
echo to_currency('LTC', 0.5); // 10.12345678
```

#### You can also convert any currency (ISO 4217 fiat or crypto) to Bitcoin:

``` php
use Jimmerioles\BitcoinCurrencyConverter\Converter;

$convert = new Converter;         // uses Coinbase as default provider
echo $convert->toBtc(100, 'USD'); // 0.12345678
echo $convert->toBtc(20, 'LTC');  // 1.12345678
```

and it also has its helper function for convenience:

``` php
// uses Coinbase as default provider
echo to_btc(100, 'USD'); // 0.12345678
echo to_btc(20, 'LTC');  // 2.12345678
```

#### You can use different exchange rates from providers:

``` php
use Jimmerioles\BitcoinCurrencyConverter\Converter;
use Jimmerioles\BitcoinCurrencyConverter\Provider\CoinbaseProvider;
use Jimmerioles\BitcoinCurrencyConverter\Provider\CoindeskProvider;
use Jimmerioles\BitcoinCurrencyConverter\Provider\BitpayProvider;

$convert = new Converter(new CoinbaseProvider);
$convert = new Converter(new CoindeskProvider);
$convert = new Converter(new BitpayProvider);
```

or if you prefer to use the helper functions:

``` php
echo to_currency('USD', 0.5, new CoindeskProvider); // 2000.00
echo to_currency('LTC', 0.5, new BitpayProvider);   // 10.12345678
echo to_btc(100, 'USD', new CoindeskProvider);      // 0.12345678
echo to_btc(20, 'LTC', new BitpayProvider);         // 2.12345678
```

#### You can specify cache expire time (ttl) on provider by:

``` php
new CoinbaseProvider($httpClient, $psr16CacheImplementation, 5); // cache expires in 5mins, defaults to 60mins
```
