final total method PHP result

I'm currently trying to create a final total method using PHP. So far I keep getting this error for the following code:

Notice: Undefined variable: finalTotal

The method does work and the final amount is calculated however I am not sure how to define the $finalTotal variable so no errors turn up. Any tips would be appreciated.

Here is the code

     $tot1=$row['productvalue']*$value; 

                       $finalTotal +=$tot1;
                     }
    echo $finalTotal;

Any tips are appreciated

It's always good practice to initialize your variable, at least IMO. In this case, to 0.

What if you add like this

$finalTotal=0;
//your loop
$tot1=$row['productvalue']*$value; 
 // rest of code

Make sure you initialize finalTotal before.

$fintalTotal = 0;

Than, perform your actions.
