Magento get all the items currently in cart programatically using below code. You can place it anywhere you wish to get information, phtml or php file. Instead of Mage::getSingleton(‘checkout/session’)->getQuote() you can also use Mage::getSingleton(‘checkout/cart’)->getQuote() to get same results. If you want to see what all product information is retrieved you can use $product->getData() inside the foreach loop to display in array format.

$cart = Mage::getSingleton(‘checkout/session’)->getQuote();  
//$cart->getAllItems() to get ALL items, parent as well as child, configurable as well as it’s simple associated item  
foreach ($cart->getAllVisibleItems() as $item) {  
 $product = $item->getProduct();  
 $name = $product->getName();  
 $sku = $product->getSku();  
}

If you want all the items in collection format, you can call below code instead:

$itemsCollection = Mage::getSingleton(‘checkout/cart’)->getQuote()->getItemsCollection();
