README

A library to retrieve currency exchanges using several web services. It's framework agnostic, so you can install it on Zend, Symfony, Silex, Yii and so on.

Installation

Add this library in your composer.json:

"require": {
	"teknoman/currency-exchange": "3.*"
}

Now tell composer to download the library by running the command:

$ php composer.phar update teknoman/currency-exchange

Composer will install the library to your project vendor/teknoman directory.

Usage

<?php

// require composer's autoload
require 'vendor/autoload.php';

$exchanger = new \CurrencyExchange\Exchanger();

// This method will print the current exchange rate from Euros to U.S. Dollars using default web service (YahooFinance)
$result = $exchanger->getExchangeRate('EUR', 'USD');

// This method will exchange 14 Euros in the correspondant U.S. Dollars, it uses the default exchange service (YahooFinance)
$result = $exchanger->exchange(14, 'EUR', 'USD');

Alternatively, you can set your preferred exchange service:

<?php

$exchanger = new \CurrencyExchange\Exchanger('GrandTrunk');

// This method will print the current exchange rate from Euros to U.S. Dollars using GrandTrunk web service
$result = $exchanger->getExchangeRate('EUR', 'USD');

// This method will exchange 14 Euros in the correspondant U.S. Dollars using GrandTrunk web service
$result = $exchanger->exchange(14, 'EUR', 'USD');

If you need to use a proxy, you can set it by invoking setProxy() method on $exchanger instance:

$exchanger->setProxy('example.host.com:8080'); // In the format 'host:port'

Release 3

In release 3.* the db part has been removed and will be included in a future new package that will require this package as a dependency. Moreover, in this release the Zend's packages has been removed and the http requests are performed with Guzzle
