Overview
A simple Laravel package used for interacting with exchange rates APIs. Laravel Exchange Rates allows you to get the latest or historical exchange rates and convert monetary values between different currencies.
Installation
You can install the package via Composer:
composer require ashallendesign/laravel-exchange-rates
The package has been developed and tested to work with the following minimum requirements:
- PHP 8.0
- Laravel 8
Supported APIs
Laravel Exchange Rates currently supports the following APIs:
Configuration
Publish the Config File
You can publish the package's config file using the following command:
php artisan vendor:publish --provider="AshAllenDesign\LaravelExchangeRates\Providers\ExchangeRatesProvider"
If you're using an API that requires an API key, you can put it in your .env
:
EXCHANGE_RATES_API_KEY={Your-API-Key-Here}
If you're using the free tier of https://exchangeratesapi.io
or https://exchangerate.host
, you should set the https
config option in config/laravel-exchange-rates.php
to false
, as the free tiers of those APIs don't allow HTTPS requests.
Usage
Methods
Available Currencies
To get the available currencies supported by the API, you can use the currencies
method like so:
use AshAllenDesign\LaravelExchangeRates\Classes\ExchangeRate; $exchangeRates = app(ExchangeRate::class); $exchangeRates->currencies();
Exchange Rate
Getting the Rate Between Two Currencies
To get the exchange rate for one currency to another, you can use the exchangeRate
method. When doing this, you can pass the currency code as a string as the second parameter. The exchangeRate
method will then return a float containing the exchange rate.
The example below shows how to get the exchange rate from 'GBP' to 'EUR' for today.
use AshAllenDesign\LaravelExchangeRates\Classes\ExchangeRate; $exchangeRates = app(ExchangeRate::class); $result = $exchangeRates->exchangeRate('GBP', 'EUR'); // $result: 1.10086
Note: If a Carbon date is passed as the third parameter, the exchange rate for that day will be returned (if valid). If no date is passed, today's exchange rate will be used.
Getting the Rate Between More Than Two Currencies
It's possible to get the exchange rates for multiple currencies in one call. This can be particularly useful if you are needing to get many exchange rates at once and don't want to make multiple API calls.
To do this, you can use exchangeRate
method and pass an array of currency code strings as the second parameter. This will return an array containing the exchange rates as floats.
The example below shows how to get the exchange rates from 'GBP' to 'EUR' and 'USD' for today:
use AshAllenDesign\LaravelExchangeRates\Classes\ExchangeRate; $exchangeRates = app(ExchangeRate::class); $result = $exchangeRates->exchangeRate('GBP', ['EUR', 'USD']); // $result: [ // 'EUR' => 1.10086, // 'USD' => 1.25622, // ];
Exchange Rates Between Date Range
Getting the Rates Between Two Currencies
To get the exchange rates between two currencies between a given date range, you can use the exchangeRateBetweenDateRange
method. When doing this, you can pass the currency code as a string as the second parameter. The method will then return an array containing the exchange rates.
The example below shows how to get the exchange rates from 'GBP' to 'EUR' for the past 3 days:
use AshAllenDesign\LaravelExchangeRates\Classes\ExchangeRate; $exchangeRates = app(ExchangeRate::class); $result = $exchangeRates->exchangeRateBetweenDateRange( 'GBP', 'EUR', Carbon::now()->subWeek(), Carbon::now() ); // $result: [ // '2020-07-07' => 1.1092623405 // '2020-07-08' => 1.1120625424 // '2020-07-09' => 1.1153867604 // ];
Getting the Rates Between More Than Two Currencies
To get the exchange rates for multiple currencies in one call, you can pass an array of currency codes strings as the second parameter to the exchangeRateBetweenDateRange
method.
The example below shows how to get the exchange rates from 'GBP' to 'EUR' and 'USD' for the past 3 days.:
use AshAllenDesign\LaravelExchangeRates\Classes\ExchangeRate; $exchangeRates = app(ExchangeRate::class); $result = $exchangeRates->exchangeRateBetweenDateRange( 'GBP', ['EUR', 'USD'], Carbon::now()->subDays(3), Carbon::now() ); // $result: [ // '2020-07-07' => [ // 'EUR' => 1.1092623405, // 'USD' => 1.2523571825, // ], // '2020-07-08' => [ // 'EUR' => 1.1120625424, // 'USD' => 1.2550737853, // ], // '2020-07-09' => [ // 'EUR' => 1.1153867604, // 'USD' => 1.2650716636, // ], // ];
Convert Currencies
When passing in the monetary value (first parameter) that is to be converted, it's important that you pass it in the lowest denomination of that currency. For example, £1 GBP would be passed in as 100 (as £1 = 100 pence).
Converting Between Two Currencies
Similar to how you can get the exchange rate from one currency to another, you can also convert a monetary value from one currency to another. To do this you can use the convert()
method.
The example below shows how to convert £1 'GBP' to 'EUR' at today's exchange rate:
use AshAllenDesign\LaravelExchangeRates\Classes\ExchangeRate; $exchangeRates = app(ExchangeRate::class); $result = $exchangeRates->convert(100, 'GBP', 'EUR', Carbon::now()); // $result: 110.15884906
Note: If a Carbon date is passed as the third parameter, the exchange rate for that day will be returned (if valid). If no date is passed, today's exchange rate will be used.
Converting Between More Than Two Currencies
You can also use the convert()
method to convert a monetary value from one currency to multiple currencies. To do this, you can pass an array of currency code strings as the third parameter.
The example below show how to convert £1 'GBP' to 'EUR' and 'USD' at today's exchange rate.
use AshAllenDesign\LaravelExchangeRates\Classes\ExchangeRate; $exchangeRates = app(ExchangeRate::class); $result = $exchangeRates->convert( 100, 'GBP', ['EUR', 'USD'], Carbon::now() ); // $result: [ // 'EUR' => 110.15884906, // 'USD' => 125.30569081 // ];
Convert Currencies Between Date Range
When passing in the monetary value (first parameter) that is to be converted, it's important that you pass it in the lowest denomination of that currency. For example, £1 GBP would be passed in as 100 (as £1 = 100 pence).
Converting Between Two Currencies in a Date Range
Similar to getting the exchange rates between a date range, you can also get convert monetary values from one currency to another using the exchange rates. To do this you can use the convertBetweenDateRange
method.
The example below shows how to convert £1 'GBP' to 'EUR' using the exchange rates for the past 3 days:
use AshAllenDesign\LaravelExchangeRates\Classes\ExchangeRate; $exchangeRates = app(ExchangeRate::class); $exchangeRates->convertBetweenDateRange( 100, 'GBP', 'EUR', Carbon::now()->subDays(3), Carbon::now() ); // $result: [ // '2020-07-07' => 110.92623405, // '2020-07-08' => 111.20625424, // '2020-07-09' => 111.53867604, // ];
Converting Between More Than Two Currencies in a Date Range
You can also use the convertBetweenDateRange
method to convert a monetary value from one currency to multiple currencies
using the exchange rates between a date range. To do this, you can pass an array of currency codes strings as the third parameter.
The example below show how to convert £1 'GBP' to 'EUR' and 'USD' at the past three days' exchange rates.
use AshAllenDesign\LaravelExchangeRates\Classes\ExchangeRate; $exchangeRates = app(ExchangeRate::class); $result = $exchangeRates->exchangeRateBetweenDateRange( 'GBP', ['EUR', 'USD'], Carbon::now()->subDays(3), Carbon::now() ); // $result: [ // '2020-07-07' => [ // 'EUR' => 110.92623405, // 'USD' => 125.23571825, // ], // '2020-07-08' => [ // 'EUR' => 111.20625424, // 'USD' => 125.50737853, // ], // '2020-07-09' => [ // 'EUR' => 111.53867604, // 'USD' => 126.50716636, // ], // ];
Facade
If you prefer to use facades in Laravel, you can choose to use the provided AshAllenDesign\LaravelExchangeRates\Facades\ExchangeRate
facade instead of instantiating the AshAllenDesign\LaravelExchangeRates\Classes\ExchangeRate
class manually.
The example below shows an example of how you could use the facade to get the available currencies:
use AshAllenDesign\LaravelExchangeRates\Facades\ExchangeRate; ExchangeRate::currencies();
Drivers
Laravel Exchange Rates provides multiple drivers so that you can interact with different exchange rate APIs.
You can select the default driver that you want to use by setting the driver
config field in the config/laravel-exchange-rates.php
config file. For example, to use the exchange-rates-api-io
driver, you could set the following:
'driver' => 'exchange-rates-api-io',
This driver will automatically be used when running methods such as:
// Using the "ExchangeRate" class: $exchangeRates = app(ExchangeRate::class); $result = $exchangeRates->exchangeRate('GBP', ['EUR', 'USD']); // Using the "ExchangeRate" facade: ExchangeRate::exchangeRate('GBP', ['EUR', 'USD']);
However, if you wish to use a different driver, you can use the driver
method to specify the driver that you want to use. For example, to use the exchange-rates-data-api
driver, you could use the following:
// Using the "ExchangeRate" class: $exchangeRates = app(ExchangeRate::class); $result = $exchangeRates ->driver('exchange-rates-data-api') ->exchangeRate('GBP', ['EUR', 'USD']); // Using the "ExchangeRate" facade: ExchangeRate::driver('exchange-rates-data-api') ->exchangeRate('GBP', ['EUR', 'USD']);
Available Drivers
The following drivers are available with the package:
Validation Rule
Laravel Exchange Rates comes with its own ValidCurrency
rule for validating currencies. This can be useful for if you need to be sure that a currency (maybe one provided by the user) is supported by at least one driver. The example below show how you can use the rule for validating the currency.
use AshAllenDesign\LaravelExchangeRates\Rules\ValidCurrency; use Illuminate\Support\Facades\Validator; $formData = [ 'currency' => 'GBP', ]; $rules = [ 'currency' => new ValidCurrency(), ]; $validator = Validator::make($formData, $rules);
This rule doesn't make a call to any APIs and instead checks an array (provided by the package) of all the currencies that are supported by at least one driver. This means that the rule will be much faster and won't cause issues with rate limits. However, it's possible that the rule may "pass" for a currency that is not supported by the driver that you are using.
If you'd prefer the validation to be stricter and return only the currencies supported by your chosen driver, you may want to write your own validation rule that makes a call to the API to get a list of supported currencies.
Caching
Busting Cached Exchange Rates
By default, all responses from the exchange rates APIs are cached. This allows for significant performance improvements and reduced bandwidth from your server.
However, if for any reason you require a fresh result from the API and not a cached result, the shouldBustCache
method can be used. The example below shows how to ignore the cached value (if one exists) and make a new API request:
use AshAllenDesign\LaravelExchangeRates\Classes\ExchangeRate; $exchangeRates = app(ExchangeRate::class); $exchangeRates->shouldBustCache() ->convert( 100, 'GBP', 'EUR', Carbon::now() );
Preventing Exchange Rates from Being Cached
It's also possible to prevent the exchange rates from being cached at all. To do this, you can use the shouldCache(false)
method. The example below shows how to get an exchange rate and not cache it:
use AshAllenDesign\LaravelExchangeRates\Classes\ExchangeRate; $exchangeRates = app(ExchangeRate::class); $exchangeRates->shouldCache(false) ->convert( 100, 'GBP', 'EUR', Carbon::now() );
Note: The caching works by storing exchange rates after fetching them from the API. As an example, if you were to fetch the exchange rates for 'GBP' to 'EUR' for 20-11-2019 - 27-11-2019, the rates between these dates will be cached as a single cache item. This cache item will only be retrieved if you attempt to fetch the same exchange rates on with the exact same currencies and date range.
Therefore, if you were to try and get 'GBP' to 'EUR' for 20-11-2019 - 26-11-2019, a new API request would be made because the date range is different.
Supported Currencies
Laravel Exchange Rates supports working with the following currencies (sorted in A-Z order):
