question about currency.php format function

there is possibility to make complex overrides to currency displaying format
Can you explain syntax of a string which i should put into $format_override ))

Subj:
function format($number,$currency_id=0,$format_override='')

More Deeply:
It shows Code instead of a Symbol after format function
I want to change it so it will show '50 руб' instead of '50 RUB'.
ThX in advance.

Hi,

In the integrated documentation you can find the different format types.

Format : The way you want to display the symbol (basically you will have %i which will display the currency code next to the price, %n which will display the currency symbol next to it, and %ni which will display both). For more information, you can look at www.php.net/manual/en/function.money-format.php

So to use the symbol instead of the code, you have to set the format %n in the settings of your currency via the menu System > Currencies.
