Sự khác biệt giữa json_encode và json_decode là gì?(mixed $value, int

if (isset($_GET['date'])) //the date given
{
    if ($_GET['roomType'] == 2)
    {
        $myFile = "bookedDates2.json";
        $date = $_GET['date'];
        if (file_exists($myFile))
        {
            $arr = json_decode(file_get_contents($myFile), true);
            if (!in_array($date, $arr['dates']))
            {
                $arr['dates'][] = $_GET['date']; //adds the date into the file if it is not there already
            }
            else
            {
                foreach ($arr['dates'] as $key => $value)
                {
                    if (in_array($date, $arr['dates']))
                    {
                        unset($arr['dates'][$key]);
                        array_values($arr['dates']);
                    }
                }
            }
        }

        $arr = json_encode($arr);
        file_put_contents($myFile, $arr);
    }
}

if (isset($_GET['date'])) //the date given
{
    if ($_GET['roomType'] == 2)
    {
        $myFile = "bookedDates2.json";
        $date = $_GET['date'];
        if (file_exists($myFile))
        {
            $arr = json_decode(file_get_contents($myFile), true);

            {
                $arr['dates'][] = $_GET['date']; //adds the date into the file if it is not there already
            }
            else
            {
                foreach ($arr['dates'] as $key => $value)
                {
                    if (in_array($date, $arr['dates']))
                    {
                        unset($arr['dates'][$key]);
                        array_values($arr['dates']);
                    }
                }

        }

        $arr = json_encode($arr);
        file_put_contents($myFile, $arr);

}

Tôi nghĩ rằng json_encode đảm bảo rằng PHP có thể đọc tệp .json nhưng bạn phải chỉ định một tên biến, trong khi với JSON_DECODE, nó giống nhau nhưng bạn phải chỉ định tên tệp.JsonSerializable to control how its values are serialized to JSON.

Làm thế nào kiểm tra mảng json trống hoặc không trong PHP?

Làm thế nào kiểm tra mảng json trống hoặc không trong PHP? Hàm php trống () hàm trống () kiểm tra xem một biến có trống hay không. Hàm này trả về sai nếu biến tồn tại và không trống, nếu không nó sẽ trả về đúng.

Hàm json_encode () có thể trả về một chuỗi chứa biểu diễn JSON của giá trị được cung cấp. Mã hóa bị ảnh hưởng bởi các tùy chọn được cung cấp, và ngoài ra, việc mã hóa các giá trị phao phụ thuộc vào giá trị của serialize_precision.

Hàm json_decode () nào sẽ trở lại?

Hàm json_decode () có thể trả về giá trị được mã hóa trong JSON theo loại PHP thích hợp. Các giá trị đúng, sai và null được trả về tương ứng là đúng, sai và null. NULL được trả về nếu JSON không thể được giải mã hoặc nếu dữ liệu được mã hóa sâu hơn giới hạn đệ quy.:

Nếu một giá trị được tuần tự hóa là một đối tượng, thì theo mặc định, chỉ bao gồm các thuộc tính hiển thị công khai sẽ được bao gồm. Ngoài ra, một lớp có thể triển khai jsonsonserializable để kiểm soát cách các giá trị của nó được tuần tự hóa thành JSON.

Ghi chú::

Trong trường hợp không thể mã hóa, json_last_error () có thể được sử dụng để xác định bản chất chính xác của lỗi.json_encode() will generate JSON that is a simple value (that is, neither an object nor an array) if given a string, int, float or bool as an input

3. While most decoders will accept these values as valid JSON, some may not, as the specification is ambiguous on this point.

Khi mã hóa một mảng, nếu các khóa không phải là một chuỗi số liên tục bắt đầu từ 0, tất cả các khóa được mã hóa dưới dạng chuỗi và được chỉ định rõ ràng cho mỗi cặp giá trị khóa.json_encode().

Giống như bộ mã hóa JSON tham chiếu, json_encode () sẽ tạo JSON là một giá trị đơn giản (nghĩa là, không phải đối tượng hay mảng) nếu được cho một chuỗi, int, float hoặc bool dưới dạng đầu vào if (isset($_GET['date'])) //the date given { if ($_GET['roomType'] == 2) { $myFile = "bookedDates2.json"; $date = $_GET['date']; if (file_exists($myFile)) { $arr = json_decode(file_get_contents($myFile), true); if (!in_array($date, $arr['dates'])) { $arr['dates'][] = $_GET['date']; //adds the date into the file if it is not there already } else { foreach ($arr['dates'] as $key => $value) { if (in_array($date, $arr['dates'])) { unset($arr['dates'][$key]); array_values($arr['dates']); } } } } $arr = json_encode($arr); file_put_contents($myFile, $arr); } } 3. Mặc dù hầu hết các bộ giải mã sẽ chấp nhận các giá trị này là JSON hợp lệ, một số có thể không, vì đặc điểm kỹ thuật không rõ ràng về điểm này.
