  • Some of them are empty?

  • Yes, the empty array may occur

  • cast to double, it must force null or '' to zero

  • 1

    Strings are not numbers, and numbers are not strings, that’s exactly what you did there, putting the 0.00 amid " "

  • I didn’t understand a thing..

  • What is this ? $r->totalProvento->totalProvento ?

  • That’s right ----> 126 ?

  • I’m just pointing out which line is coming wrong

You are doing your if wrong, because if you enter the first condition, you will not enter Else which is where the sum occurs a returns the typing error.

Try this:

$totalProvento = ($r->totalProvento==NULL ? 0.00 : ($r->totalProvento->totalProvento + $r->salario));
$totalDesconto = ($r->totalProvento==NULL ? 0.00 : $r->totalDesconto->totalDesconto);
$totalReceber = ($r->totalProvento==NULL ? 0.00 : ($totalProvento - $totalDesconto));

// ou

if($r->totalProvento==NULL){
    #total a receber
    $totalProvento = 0.00;
    $totalDesconto = 0.00;
    $totalReceber = 0.00;
}

$totalProvento = ($r->totalProvento->totalProvento + $r->salario);
$totalDesconto = $r->totalDesconto->totalDesconto;
$totalReceber = ($totalProvento - $totalDesconto);
