Swap

Build status Total Downloads Scrutinizer Version

Swap allows you to retrieve currency exchange rates from various services such as Fixer or currencylayer and optionally cache the results. It is integrated to other libraries like moneyphp/money and provides a Symfony Bundle and a Laravel Package.

QuickStart

$ composer require php-http/curl-client nyholm/psr7 php-http/message florianv/swap
use Swap\Builder;

// Build Swap
$swap = (new Builder())

    // Use the Fixer.io service as first level provider
    ->add('fixer', ['access_key' => 'your-access-key'])

    // Use the currencylayer.com service as first fallback
    ->add('currency_layer', ['access_key' => 'secret', 'enterprise' => false])

->build();

// Get the latest EUR/USD rate
$rate = $swap->latest('EUR/USD');

// 1.129
$rate->getValue();

// 2016-08-26
$rate->getDate()->format('Y-m-d');

// Get the EUR/USD rate 15 days ago
$rate = $swap->historical('EUR/USD', (new \DateTime())->modify('-15 days'));
