MAGENTO-REMOVE ALL ITEMS FROM THE CART

//THIS WORKED FINE FOR ME :)

$session= Mage::getSingleton('checkout/session');
$quote = $session->getQuote();
$cart = Mage::getModel('checkout/cart');
$cartItems = $cart->getItems();
foreach ($cartItems as $item)
{
   $quote->removeItem($item->getId())->save();
}
