A small PHP **currency converter** using the official daily exchange-rate table published by the Czech National Bank (CNB).

It can:

- ✅ show the official CZK quote for a given currency,
- ✅ normalize CNB rates quoted for 1, 100 or 1000 units,
- ✅ convert any supported currency to any other supported currency through CZK,
- ✅ load the latest available CNB exchange-rate table,
- ✅ load a historical CNB table by date,
- ✅ cache downloaded tables for one day,
- ✅ use Symfony Cache out of the box,
- ✅ accept any PSR-6 cache pool,
- ✅ work in older PHP 7.1.3 systems and modern PHP 8.x projects.
