Yes. You can just get this code and place it inside the existing class
Code:
public static function formatCurrency($amount, $config, $currencySymbol = null)
{
$decimals = isset($config->decimals) ? $config->decimals : 2;
$dec_point = isset($config->dec_point) ? $config->dec_point : '.';
$thousands_sep = isset($config->thousands_sep) ? $config->thousands_sep : ',';
$symbol = $currencySymbol ? $currencySymbol : $config->currency_symbol;
return $config->currency_position ? (number_format($amount, $decimals, $dec_point, $thousands_sep) . ' ' . $symbol) : ($symbol . ' ' .
number_format($amount, $decimals, $dec_point, $thousands_sep));
}
