Hello,

Utilize json_decode to get a PHP variable containing the values. From there, itere for the variable and sum all the elements:

   $meu_array = json_decode($json);

    $soma = 0;
    foreach($meu_array as $elementoAtual){
        $soma += $elementoAtual['totalValue'];
    }

This works for a json with N elements, but if it’s only 2, you can simplify:

   $soma = $meu_array[0]['totalValue'] + $meu_array[1]['totalValue']
