Swap - A PHP exchange rates library
Swap is a PHP library helping you to retrieve exchange rates for currency pairs from different providers such as Google and Yahoo finance, the European Central Bank and more.
Additionally, you can set up a chain of providers in order to prevent downtimes from the main one, and cache fetched rates in your favorite storage.
To install the latest version with Composer, issue the following command
$ composer require florianv/swap
<?php // Create an HTTP adapter provided by the egeloen/ivory-http-adapter library $httpAdapter = new \Ivory\HttpAdapter\FileGetContentsHttpAdapter(); // Create the Yahoo Finance provider $yahooProvider = new \Swap\Provider\YahooFinanceProvider($httpAdapter); // Create Swap with the provider $swap = new \Swap\Swap($yahooProvider); // Retrieve the latest exchange rate $rate = $swap->quote('EUR/USD'); // 1.187220 echo $rate; // 1.187220 echo $rate->getValue(); // 15-01-11 21:30:00 echo $rate->getDate()->format('Y-m-d H:i:s');
This example only shows the basic features of the library and you are invited to check the complete documentation to know about all its functionalities.
