php - PHP 会话未初始化

Question

我有一个会话：

session_start();
$_SESSION['auth'] = "true";

并设置了 PHPSESSID cookie 。但是，当我刷新页面$_SESSION['auth']时返回 NULL。此外，当我打电话时，session_destroy();我收到错误Trying to destroy uninitialized session

如何保持会话打开？谢谢！

试一试..如果可行，我将重新检查您的代码+注释掉 session_destroy ...

page1.php

<?php
    session_start();
    $_SESSION['auth'] = "true";
    $_SESSION['superhero'] = "batman";
?>
<a href="page2.php">Click here</a>

page2.php

<?php
    session_start(); // start the session before using it
    echo $_SESSION['auth']; // will output 'true'
    //print_r($_SESSION); // uncomment for testing
?>
