PHP session 在本地主机上工作，但在实际服务器上不工作

Question

我无法将 session 变量传递到另一个页面。它在本地主机上工作，但不在服务器上工作。我想将 $_SESSION['user_check'] 传递给 editpasswordsignup.php，但每当我单击提交时，$_SESSION['user_check'] 都是空的。

这是 loginsignup.php

<?php

include('db.php');

session_start(); 

?>

正如您所说，它在本地主机上工作，而不是在特定服务器上工作，您可能在 php.ini 中有不同的设置。查看http://php.net/manual/en/session.configuration.php
