Use Currency 7.x-2.x to display prices

Currency 7.x-2.x contains a class called CurrencyLocalePattern that can be used to format/display prices using the current user's localization. For a price of EUR123456.78, Dutch users would see €123.456,78, American users would see €123,456.78, and Hindi users would see € 1,23,456.78, exactly as they expect prices to be formatted. Here's a short usage example:

$currency_code = 'EUR';
// Make sure the price is a float.
$price = 123456.78;

$currency = currency_load($currency_code);
// This loads the correct formatting pattern based on current environment variables, such as language and country.
$locale_pattern = CurrencyLocalePattern::loadFromEnv();
echo $locale_pattern->format($currency, $price);
