Question

我们有一个CentOS 5.4服务器服务于我们的许多网站。服务器由Plesk 9.2.3管理。我们的网站是用PHP开发的。

我们的主域名ourapplication.co.uk位于/var/www/vhosts/ourapplication.co.uk/httpdocs，并且我们的子域名api.ourapplication.co.uk在/ var / www / vhosts / ourapplication / subdomains / api / httpdocs

以下页面位于两个位置：

davidstest1.php

<?php
session_start();
?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1" />
<meta http-equiv="X-UA-Compatible" content="IE=7" />
<title>Code Blue Stats</title>
<link rel="stylesheet" type="text/css" href="css/style.css" />
</head>
<body>
<?php
echo "This is Davids Test 1. It will set SESSION['davids']='davids variable set' and then link
to davidstest2.php<br />
davidstest2 wil then do a session_start() call, and attempt to display SESSION['davids'] <br />";
$_SESSION['davids']='davids variable set';
?>
<a href="davidstest2.php">davidstest2.php</a>
</body>
</html>

davidstest2.php

<?php
session_start();
?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1" />
<meta http-equiv="X-UA-Compatible" content="IE=7" />
<title>Code Blue Stats</title>
<link rel="stylesheet" type="text/css" href="css/style.css" />
</head>
<body>
<?php
echo "This is Davids Test 2. It will do a session_start() call, and attempt to display SESSION['davids'] <br />";
$r=print_r($_SESSION, true);
echo "<pre>Session in <br />";
echo $r;
echo "<br /></pre>";
?>
<a href="davidstest2.php">davidstest2.php</a>
</body>
</html>

在MAIN域中，davidstest2返回

This is Davids Test 2. It will do a session_start() call, and attempt to display SESSION['davids'] 
Session in 
Array
(
    [siteMode] => none
    [davids] => davids variable set
) 
davidstest2.php

在api SUBDOMAIN中，davidstest2返回

This is Davids Test 2. It will do a session_start() call, and attempt to display SESSION['davids'] 
Session in 
Array
(
)
davidstest2.php

显然，Apache配置或Php配置中的某些内容是错误的，因为会话变量应该存储在两个域中

Relevant phpinfo() reports:

session.serialize_handler   php php

session.use_trans_sid   0   0

任何想法从哪里开始寻找？

Answer 1

将session.cookie_domain设置为.ourapplication.co.uk（请注意开头的点），以使会话Cookie对 ourapplication.co.uk 及其所有子域有效。

Answer 2

session.cookie_domain应根据http://php.net/setcookie

中说明的Cookie域设置进行设置

session_set_cookie_params（）函数通常用于此

PHP不保存子域上的会话，在域上确定
