为什么我在 PHP 中的第一个会话没有向第二个会话发送数据？

Question

我正在尝试让一个会话将页面中的数据输入到 post 数组，然后将其存储到会话数组，然后将其发送到会话 2，我希望将信息发送到会话 2被显示。我的第一个会话将我发送到我的会话 2 页面，但没有显示信息。谁能告诉我我的代码是否有问题？谢谢

Answer 1

首先，确保您的会话在重定向之前已保存，您可以使用 session_write_close()。

其次，确保您的脚本在重定向后立即完成，使用退出。

您可以使用一个同时执行这两个操作的函数来节省代码：

session_start();

if(isset($_POST["employeeNameBox"]))
{
    $_SESSION["employeeName"] = $_POST["employeeNameBox"];
    my_redirect('Session2.php');
}

//Here rest of vars

function my_redirect($to)
{
    session_write_close();
    header('Location: ' . $to);
    exit;
}

为什么我在 PHP 中的第一个会话没有向第二个会话发送数据？
