I guess your purpose is to just save the row data from the mysql to the
array each unit. So may be the result that you expected is sth like:
$product[0] = 1;
$product[1] = 2;
$product[2] = 3;
...
If you just "loop for each new value in the loop and to destroy the array",
you second example is okey.

To destroy an array?
First of all, where does $product_id come from? You gave us no code
that gives us that.
Second, if you're trying to make an array populated with a feild from
each row returned, your first example will work, but not the second.
The second example will empty the array, and start a new one (which
doesn't make sense to me why you would do that--because in the end,
you're only going to have the array with the last row returned).
But if you're trying to destroy an array doing either:
unset($an_array)
or $an_array = array();
will do the job.
