Get the current currency code and symbol in magento

I have tried many times but I didn’t got success . But today I got the solution to show the currency symbol of product price:

Currency Code :

<?php echo $currency_code = Mage::app()->getStore()->getCurrentCurrencyCode(); ?>

Currency Symbol :

<?php echo Mage::app()->getLocale()->currency(Mage::app()->getStore()->getCurrentCurrencyCode())->getSymbol(); ?>
