Currency exchange rates library for PHP
Swap allows you to retrieve currency exchange rates from various services such as Fixer or Google and optionally cache the results.
It is integrated to other libraries like moneyphp/money and provides
a Symfony Bundle and a Laravel Package.
$ composer require florianv/swap php-http/message php-http/guzzle6-adapteruse Swap\Builder;

// Get the latest EUR/USD rate
$rate = $swap->latest('EUR/USD');
// 1.129
$rate->getValue();
// 2016-08-26
$rate->getDate()->format('Y-m-d');
