Error: Warning: A non-numeric value encountered in php code

Question

I have a problem in my php code. does anyone know how to fix this? Help me please! Warning: A non-numeric value encountered in C:\xampp\htdocs\stock\dashboard.php on line 15

Code:

$totalRevenue = "";
while ($orderResult = $orderQuery->fetch_assoc()) {
    $totalRevenue += $orderResult['paid'];
}

Set `$totalRevenue` to 0, not an empty string, when you declare it. — aynber, Apr 11 '19 at 14:25
