How to get ordered Items and their detail for an order ID in Magento?

I tried to wrote this code when I was working on a cron file for all orders. My client wants a cron file that get all orders information including all ordered item and their detail.

First, I searched on google but I didn’t found any exact solution then I tried below code:

By below code I got all orders on site:

$orders = Mage::getModel('sales/order')->getCollection();

Now, I am going to fetch all ordered items for each order.

foreach ($orders as $order) {
    $items = $order->getAllItems();
    foreach ($items as $itemId => $item)
    {
	echo $item->getName();
	echo '
';
	echo $item->getPrice();
	echo '
';
	echo $item->getQtyToInvoice();
	echo '
';
        echo $item->getQtyOrdered();
     }
}
