$con = mysqli_connect("localhost", "root", "", "zoo");

if (mysqli_connect_error()) {
    echo "Failed to connect" . mysqli_connect_error();
}

$sel = "select (quantity* bill) as total from animal inner join price on animal.id=price.animal_id group by price.animal_id";
$result = mysqli_query($con, $sel);
while ($row = mysqli_fetch_array($result)) {
