Integrate the powerful Exchange Rates API from Abstract in your PHP project in a few lines of code.
The Exchange Rate API is an REST API that allows you to:
- look up the latest exchange rates for 80+ currencies via the live endpoint
- get historical exchange rates using the historical endpoint
- convert an arbitrary amount from one currency to another using the convert endpoint
It's very simple to use: you only need to submit your API key and a currency symbol (such as "USD"), and the API will respond with current exchange rate, historical data, or convertion rates.
This library supports the PHP version 5.6 and higher.
You can install php-exchange-rates via composer or by downloading the source.
php-exchange-rates is available on Packagist as the
abstractapi/php-exchange-rates package:
composer require abstractapi/php-exchange-ratesGet your API key for free and without hassle from the Abstact website.
<?php
$api_key = "YYYYYY"; // Get your API Key from https://app.abstractapi.com/api/exchange-rates/documentation
Abstractapi\ExchangeRates\AbstractExchangeRates::configure($api_key);
// Get live exchange rates using Abstract's Exchange Rates API and PHP
$info = Abstractapi\ExchangeRates\AbstractExchangeRates::live('EUR');
var_dump($info);
// Get historical exchange rates using Abstract's Exchange Rates API and PHP
$info = Abstractapi\ExchangeRates\AbstractExchangeRates::historical('EUR', '2021-05-01');
var_dump($info);
// Convert currency using Abstract's Exchange Rates API and PHP
$info = Abstractapi\ExchangeRates\AbstractExchangeRates::convert('EUR', 'USD');
var_dump($info);The API response contains the following fields:
