PHP 多域会话；ini_set 不工作? [英] PHP Multi-Domain Sessions; ini_set Not Working?

问题描述

我正在尝试设置它，因此如果您登录到我的网站，会话会转移到我网站的所有子域.例如，如果您转到 domain.com 并登录，然后转到 sub.domain.com，则您已经在 sub.domain.com 上登录了.

I'm trying to set it up so if you log in to my website the session carries over to all sub-domains of my website. For example, if you go to domain.com and log in, then go to sub.domain.com, you'll already be logged in at sub.domain.com.

据我所知，您可能想使用 ini_set('session.cookie_domain','.domain.com') 然后 session_start()，然后设置会话变量，但这不起作用.

To my understanding, you would want to use ini_set('session.cookie_domain','.domain.com') and then session_start(), then set your session variables, but this isn't working.

我正在做的事情的例子:

Example of what I'm doing:

domain.com 的代码:

Code for domain.com:

<?php
 ini_set('session.cookie_domain','.domain.com');
 session_start();
 $_SESSION['variable'] = 1;
?>

sub.domain.com 的代码:

Code for sub.domain.com:

<?php
 session_start();
 echo $_SESSION['variable'];
?>

但是 $_SESSION['variable'] 没有设置.

But $_SESSION['variable'] isn't set.

我也试过在 sub.domain.com 代码中使用 ini_set()，但没有任何区别.我已经通过使用 ini_get() 验证了设置 session.cookie_domain 是否有效.

I've also tried using ini_set() in the sub.domain.com code, but it made no difference. I've verified that setting session.cookie_domain is working by using ini_get().

我做错了什么?谢谢！

推荐答案

先验证ini_set

<?php
ini_set('session.cookie_domain','.domain.com');

echo ini_get('session.cookie_domain');

session_start();  
$_SESSION['variable'] = 1; 

?> 

<小时>

更新:

刚刚想了一下..你也试过吗:

Just thought about it.. Did you also try:

<?php

session_set_cookie_params( 0, "/", ".domain.com", false, false); 
session_start();  
$_SESSION['variable'] = 1; 

?> 

<小时>

更新 2:替代处理(手动 cookie 处理)

---

Update 2: ALternate handling (manual cookie handling)

<?php

session_start();  
session_regenerate_id();
$_SESSION['variable'] = "String Test";

setcookie('PHPSESSID',session_id(),time()+86400,'/','.domain.com');
echo session_id();
?> 

并在子域文件中

<?php  
if (isset($_COOKIE['PHPSESSID']) && !empty($_COOKIE['PHPSESSID'])) session_id($_COOKIE['PHPSESSID']);

session_start();  
echo $_SESSION['variable'] . "<br />"; 
echo $_COOKIE['PHPSESSID'] . "<br />";
echo session_id();
?> 

<小时>

您可以在每个文件中添加三行来传递/处理会话信息

---

Three lines you could add to every file to hand off / handle session info

if (isset($_COOKIE['PHPSESSID']) && !empty($_COOKIE['PHPSESSID'])) session_id($_COOKIE['PHPSESSID']);
session_start();  
if (!isset($_COOKIE['PHPSESSID'])) setcookie('PHPSESSID',session_id(),time()+86400,'/','.domain.com');

您通过会话传递了哪些信息?或者你用它来处理登录等?

What info are you passing through the session? Or are you using it to handle logins, etc?
