Get product attributes from its id

[prestashop_newuser]

In Prestashop I want to get product's all attribute from its product id. Lets say I have a product with id as 3. Now from product id 3 I want to get all of its attribute like name, price, stock, category, product link.. etc.

So far I have tried

 

$product_id = $result['id_product'];
$id_product = (int)$product_id;
$product = new Product(Tools::getValue($id_product));
var_dump($product);

 

But its giving me an array with all attributes in blank. The array can be seen here

So can someone tell me how to get its all attribute from id? Any help and suggestions will be really appreciable. Thanks

Is $result['id_product'] really 3?
