Question

我无法通过NSJSONSerialization序列化负整数。

目标C：

if ($_POST) {
    $first_number = $_POST['first_number'];
    $second_number = $_POST['second_number'];
    $cal = $_POST['cal'];

    switch ('$cal') {
        case "Addition":
            $result = $first_number + $second_number;
            break;
        case "Subtraction":
            $result = $first_number - $second_number;
            break;
        case "Multiplication":
            $result = $first_number * $second_number;
            break;
        case "Division":
            $result = $first_number / $second_number;
            break;
        case "Modulation":
            $result = $first_number % $second_number;
            break;
    }
    return $result;
}
echo "$cal <br /> <br /> 1st Number: $first_number <br /> 2nd Number: $second_number <br /><br />";
echo "Answer is:" . $result;

如何序列化负整数？

你纠正了，一切都很好。这只是字典 - 描述有误导性。
