Here, I will show you how you can get information about all items in your Magento Shopping Cart. You will see how you can :-)

Get all items information in cart

// $items = Mage::getModel('checkout/cart')->getQuote()->getAllItems();
$items = Mage::getSingleton('checkout/session')->getQuote()->getAllItems();
foreach($items as $item) {
	echo 'ID: '.$item->getProductId().'<br />';
	echo 'Name: '.$item->getName().'<br />';
	echo 'Sku: '.$item->getSku().'<br />';
	echo 'Quantity: '.$item->getQty().'<br />';
	echo 'Price: '.$item->getPrice().'<br />';
	echo "<br />";

Get total items and total quantity in cart

$totalItems = Mage::getModel('checkout/cart')->getQuote()->getItemsCount();
$totalQuantity = Mage::getModel('checkout/cart')->getQuote()->getItemsQty();

Get subtotal and grand total price of cart

$subTotal = Mage::getModel('checkout/cart')->getQuote()->getSubtotal();
$grandTotal = Mage::getModel('checkout/cart')->getQuote()->getGrandTotal();

Hope this helps. Thanks.
