我对会话处理感到困惑。我想访问我的索引页面，无论用户是否登录。但是，如果用户登录，那么我想更换我的登录名并注销按钮。如果没有登录，则显示登录和注册菜单。但在这两种情况下，索引页都应该可以访问。 当我在头中包含会话文件时，索引页仅显示为登录用户。如果我只写session_start（）;在与页面顶部检查我想访问index.php登录或不登录索引页登录详细信息
if(isset $_SESSION['login_user'])
{ echo $login_session
}
//index.php
<?php
$currentPage = 'index';
include_once "header.php"; ?>
\t <div class="stle">
<h1> welcome to home page</h1>
//menus
//slider
// posts
</div>
<?php include_once "footer.php"; ?>//session.php
<?php
include('dbconn.php');
session_start();
$user_check = $_SESSION['login_user'];
/* $ses_sql = mysqli_query($conn,"select name,email from signup_work where email = '$user_check' ");*/
$ses_sql = mysqli_query($conn,"SELECT name,email
FROM signup_hire
WHERE signup_hire.email = '$user_check'
UNION
SELECT name,email
FROM signup_work
WHERE signup_work.email = '$user_check' ");
$row = mysqli_fetch_array($ses_sql,MYSQLI_ASSOC);
/*printf("Error: %s\n", mysqli_error($conn));
exit();*/
$login_session = $row['name'];
if(!isset($_SESSION['login_user'])){
header("location:login.php");
}
?>// header.php
<?php session_start();
$login_session=""; ?>

为了这个，我必须包括session.php文件文件头和头是相同的所有它会要求先登录的文件 –
和什么是logged_in –
为什么不只是使用Session_start（）; ？那么你的sesssion就开始了，你可以在上面的答案中使用它。 – SteffenCH
