Where and how to get the historical exchange rate?

Question

API

1.Where and how to get historical exchange rates for the site? (but not in the form of inserting a code, but in the form of obtaining a value for further use.)
i.e., for example, the rate of the Moroccan dinar on 1.1.2013
2. "How to take it" i.e. Interested in some php function with parameters (currency, date, currency in which to convert) which returns the value of the exchange rate.
3. Whether there are standard functions of "normalization" of a format. Those. for example, they usually do not write that 1 Japanese yen is worth 1 US cent, they write that 100 Japanese yen is worth 1 dollar.
Thanks

You make a script for searching and saving to the database.
I downloaded all the courses for the site since 1991 into the MySQL database, the size turned out to be 30mb.
