A Codeigniter library to convert your price from a currency to another

Background

Is very frequently that inside your sites you need to convert your price from a currency to another. This library convert your price in every currency of the world.

It works with fixer.io api and store currency rates inside the site database if you want. User can configure in hour the time of currency rates update, if the user doesn't want to use database, rates are updated every time with the current conversion.

If you have set to use database, for example, user sets to update currency rates every hour, this library get the currency conversion from fixer.io the first time, store it inside the database and for the next hour it takes conversion rates from the database if exist. In this way reduce the request time to convert and every hour currency rates are updated.

If you haven't set to use database, instead, every time you call the library it makes a request to fixer.io api and gets the actual conversion rate. This solution is great if you have not a lot of request. Instead, if you have a lot of conversion request is better to use the database configuration.

Requirements

CodeIgniter 2.x or 3.x
PHP 5.3 or gretaer

With composer you can install this package:

composer require alessandrominoccheri/codeigniter-currency-converter

It's important to have a valid database connection because the library saves conversion inside it if you want to use it.
