Application made with PHP and JavaScript that displays and converts currency exchange rates with data from European Central Bank (ECB).
This script displays foreign exchange rates according to a base currency, and it can convert the sum of a currency in the other currencies (optionally you can calculate the sum with a VAT percentage).
The script uses the exchange rates from an .xml file directly from ECB, and can be registered into a MySQL database. It uses cache file that is actualized every 5 hours and around 16:00 CET (when data from ECB is usually updated).

- This application can easily be included in any web page, with a simple HTML code. Installation instructions in a "readme.txt" file in the archive with the script.
