我有一个登录页面，该页面将变量发送到另一个页面，验证登录是真(1(还是假(0(。我可以在第 1 页上回显 $_SESSION['logon']，但就在我转到第 2 页时，我的会话似乎已经死了，给了我 * 注意：未定义的索引：登录 * 我已经摆弄了 php.ini但无济于事。顺便说一下，Register_globals = 关闭。我是菜鸟，所以我可能传递了一些错误的东西，没有在 php.ini 中更改正确的参数，不知道。
登录页面：

对于我可能发送的任何错别字，我深表歉意。
您在echo之前使用exit，您需要检查pag2的条件.php如下所示：
if(isset($_SESSION['logon']) && $_SESSION['logon'] != "") {
$logon=$_SESSION['logon'];
if($logon==0){
//header("Location: index.php");
echo $_SESSION['logon'];
exit();
}
}
