Websitecode, currency, language (for sonician)

Problem:
get through code the current values for website, currency and language.
Hello,
Website:

//for name
Mage::app()->getWebsite()->getName();
//for code
Mage::app()->getWebsite()->getCode();

Currency:

Mage::app()->getStore()->getCurrentCurrencyCode();

Language:
This is a little tricky. You can get the ISO code for the language, because by standards French for France is different from French for Belgium

Mage::app()->getLocale()->getLocale();//will return something like fr_FR, fr_BE or en_US

if you want to go further and see only the language code it's simple

$isoCode = Mage::app()->getLocale()->getLocale();
$parts = explode("_", $isoCode);
$language = $parts[0];
$country = $parts[1];
