How to get product quantity : Magento

Sometimes we want to show remaining quantity of a product in our magento shop. Simple method to get product quantity is:

<?php (int) Mage::getModel(‘cataloginventory/stock_item’)->loadByProduct($_product)->getQty(); ?>

It can be helpful to show an alert message like below:

<?php $product_qty=(int) Mage::getModel(‘cataloginventory/stock_item’)->loadByProduct($_product)->getQty();

if($product_qty<5)

echo “Hurry up $product_qty quantity remaining”;

?>
