// Load currency data from library require_once('path/to/currency_library.php'); // Get USD currency data $usd_data = Currency::getByCode('USD'); // Display currency information echo $usd_data->getName() . "\n"; echo $usd_data->getSymbol() . "\n"; echo $usd_data->getExchangeRate() . "\n";In this example, we're using the getByCode method to retrieve currency data for the USD currency code. We then use the retrieved data to display the name, symbol, and exchange rate of the USD currency. Based on the use of the `Currency` class and method, it's likely that this code belongs to a currency conversion or financial package library.
