【中文标题】会话变量未在实时服务器中传递[关闭]【英文标题】：Session variable not passed in live server [closed] 【发布时间】：2016-04-05 08:27:26 【问题描述】：我已经在 php 中尝试了一些用于用户注册的代码，这整个代码在本地服务器上运行良好，但是当涉及到实时服务器时，每个 php 代码都会被执行，但会话变量不会显示，但在本地服务器会话变量被传递并且正确显示

【问题讨论】：
您是否也在 form.php 页面上启动了会话？ 您必须使用会话变量在每个页面上使用session_start()。
只有在创建新用户时才会设置会话变量；因此，如果您在会话数组中看不到任何内容，则表示未创建用户。
这里看不出有什么错误，cmets和answer足以解决这个问题。你可能想看看my answer here。如果这也不能解决您的问题，请联系您的托管服务提供商。
您需要制作php.ini 文件并将这一行添加到该文件中：session.save_path = "/temp/php_sessions"。您需要创建文件夹temp，然后将其他php_sessions 文件夹创建到当前temp 文件夹中。
【参考方案1】：
在声明会话变量之前你有空间。
<?php
session_start();
?>
注意<?php. 之前的空格，这会产生问题，因此只需将其删除即可。
【讨论】：
好吧...先生试试..!! 注意：这仅适用于 PHP 手册中所述的基于 cookie 的会话 - “要使用基于 cookie 的会话，必须在向浏览器输出任何内容之前调用 session_start()。” - php.net/manual/en/function.session-start.php 先生..我发现您的回答有效..!!【参考方案2】：session_start() 函数必须是文档中的第一件事。在任何 HTML 标记之前。 试试这个：
<?php
session_start();
?>
<!DOCTYPE html>
<html>
<body>【讨论】：
是的，先生完成了更改，但遗憾的是没有工作..!! 注意：这仅适用于 PHP 手册中所述的基于 cookie 的会话 - “要使用基于 cookie 的会话，必须在向浏览器输出任何内容之前调用 session_start()。” - php.net/manual/en/function.session-start.php soo..先生，如果我出错了，请指导我..！！【参考方案3】：您已将fullName 保存为$_SESSION["user"]["fullname"]：
$_SESSION["user"]["fullname"] = $user["fullname"];
但你是这样呼应的：
echo $_SESSION["fullname"];
修复它以回显正确的：
echo $_SESSION["user"]["fullname"];
注意：您可以使用附加检查if(isset($_SESSION["user"]["fullname"]))，以便在未实际设置时不会出错。但这在您使用正确的变量/键之前不会解决任何问题。
【讨论】：
先生，我已经编辑了我的代码..实际上那是一个旧代码，现在我已经按照上面的方法进行了更改....!!! 作为你的建议我已经删除了我的答案..!! plzz ..检查代码...任何建议都敞开心扉接受..!! 谢谢，您还可以为您的$db->storeUser() 函数添加代码吗？或者至少是此函数返回的$user 数组的样本。
给你先生...！！以上是关于会话变量未在实时服务器中传递[关闭]的主要内容，如果未能解决你的问题，请参考以下文章
