Hi Sarmila,
Use the below code to get product Information based on Product Id
$_product = Mage::getModel(‘catalog/product’)->load($product_id); // Enter your Product Id in $product_id
echo $_product->getName(); // get Product’s name
echo $_product->getShortDescription(); //get product’s short description
echo $_product->getDescription(); //get Product’s Long Description
echo $_product->getPrice(); //get Product’s Regular Price
echo $_product->getSpecialPrice(); //get Product’s Special price
echo $_product->getProductUrl(); //get Product’s Url
echo $_product->getImageUrl(); //get Product’s image Url
If you need attributes like brand and manufacturer for that product you can get in same way.
