Php 在include（）页中无法识别会话（不是重复的）

IDK为什么这个家伙一直把它当作重复的不是我看了其他的例子，他们不会解决这个问题

我有一个会话，当我在一个页面上使用它时，它无法被识别，然后被包含在另一个页面中，如下所示：

nav.php

include('login.php'); // Has session variables in it
if(isset($_SESSION['login_user'])){
  echo '<span>Dash</span>';
}
else{
  echo '<span>Login</span>';
}

<?php include('nav.php'); ?>

include('login.php'); // Has session variables in it
if(isset($_SESSION['login_user'])){
  echo '<span>Dash</span>';
}
else{
  echo '<span>Login</span>';
}

session_set_cookie_params(60 * 30, "/", "domain.com", true); // also tried '.domain.com'
session_name("login_user");
session_start();

session_start();
if(isset($_COOKIE["login_user"])) {
  echo 'Dash';
}
else { 
  session_unset(); 
  session_destroy(); 
  session_abort(); 
}

include('login.php');
echo $_SESSION["login_user"];

include('nav.php');

include('login.php');
echo $_SESSION["login_user"];

index.php

include('login.php'); // Has session variables in it
if(isset($_SESSION['login_user'])){
  echo '<span>Dash</span>';
}
else{
  echo '<span>Login</span>';
}

<?php include('nav.php'); ?>

include('login.php'); // Has session variables in it
if(isset($_SESSION['login_user'])){
  echo '<span>Dash</span>';
}
else{
  echo '<span>Login</span>';
}

session_set_cookie_params(60 * 30, "/", "domain.com", true); // also tried '.domain.com'
session_name("login_user");
session_start();

session_start();
if(isset($_COOKIE["login_user"])) {
  echo 'Dash';
}
else { 
  session_unset(); 
  session_destroy(); 
  session_abort(); 
}

include('login.php');
echo $_SESSION["login_user"];

include('nav.php');

include('login.php');
echo $_SESSION["login_user"];

出于某种原因，新代码没有任何作用

我不确定这是否有帮助，但我尝试回显$\u会话变量，结果如下：

nav.php

include('login.php'); // Has session variables in it
if(isset($_SESSION['login_user'])){
  echo '<span>Dash</span>';
}
else{
  echo '<span>Login</span>';
}

<?php include('nav.php'); ?>

include('login.php'); // Has session variables in it
if(isset($_SESSION['login_user'])){
  echo '<span>Dash</span>';
}
else{
  echo '<span>Login</span>';
}

session_set_cookie_params(60 * 30, "/", "domain.com", true); // also tried '.domain.com'
session_name("login_user");
session_start();

session_start();
if(isset($_COOKIE["login_user"])) {
  echo 'Dash';
}
else { 
  session_unset(); 
  session_destroy(); 
  session_abort(); 
}

include('login.php');
echo $_SESSION["login_user"];

include('nav.php');

include('login.php');
echo $_SESSION["login_user"];

index.php

include('login.php'); // Has session variables in it
if(isset($_SESSION['login_user'])){
  echo '<span>Dash</span>';
}
else{
  echo '<span>Login</span>';
}

<?php include('nav.php'); ?>

include('login.php'); // Has session variables in it
if(isset($_SESSION['login_user'])){
  echo '<span>Dash</span>';
}
else{
  echo '<span>Login</span>';
}

session_set_cookie_params(60 * 30, "/", "domain.com", true); // also tried '.domain.com'
session_name("login_user");
session_start();

session_start();
if(isset($_COOKIE["login_user"])) {
  echo 'Dash';
}
else { 
  session_unset(); 
  session_destroy(); 
  session_abort(); 
}

include('login.php');
echo $_SESSION["login_user"];

include('nav.php');

include('login.php');
echo $_SESSION["login_user"];

此操作的输出是一个通知：

Notice: Undefined index: login_user in nav.php on line 28

但是当我尝试像这样回显代码时：

index.php

include('login.php'); // Has session variables in it
if(isset($_SESSION['login_user'])){
  echo '<span>Dash</span>';
}
else{
  echo '<span>Login</span>';
}

<?php include('nav.php'); ?>

include('login.php'); // Has session variables in it
if(isset($_SESSION['login_user'])){
  echo '<span>Dash</span>';
}
else{
  echo '<span>Login</span>';
}

session_set_cookie_params(60 * 30, "/", "domain.com", true); // also tried '.domain.com'
session_name("login_user");
session_start();

session_start();
if(isset($_COOKIE["login_user"])) {
  echo 'Dash';
}
else { 
  session_unset(); 
  session_destroy(); 
  session_abort(); 
}

include('login.php');
echo $_SESSION["login_user"];

include('nav.php');

include('login.php');
echo $_SESSION["login_user"];

输出是实际的用户名

我认为，出于某种原因，当您使用“include（）”来包含查找会话的代码时，它就失败了。当您直接使用代码而不包含另一个包含该代码的文档时，它可以完美地工作。

尝试使用Sessioncookie我可以在浏览器中看到PHPSESSID和cfduid cookies，如果这有帮助的话。。我应该执行什么参数？我现在在手机上。将在明天提供一些想法。你在哪里使用session_start（），它在login.php中，包含在顶部。尝试使用sessionokie我可以在浏览器中看到phpsID和cfduid cookies，如果有帮助的话。。我应该执行什么参数？我现在在手机上。你在哪里使用session_start（），它在login.php中，它包含在顶部。
