Currency conversion script

You need a script on php on the site written on yii 1.1. The script may not be integrated into the framework.



The script must download data from the open official API or pars data on official websites at the exchange rate.



Once downloaded, you must transfer prices depending on the currency in which it is listed.



Currencies: Estonia, Finland, Sweden, Norway, Denmark, Lithuania, Poland,



When testing, the script must collect data on all these currencies and transfer prices.



You need to cache so that the data is collected once or as much per day.



The script should have all the important variables to make it easy to customize.
