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'));
