好的,这是我的问题: 当用户登录我的网站时,我将所有用户信息放入这样的会话
session_start();
//Put all user info into session cookie
$_SESSION["login"] = 'true';
$_SESSION["id"] = $user_info['id'];
$_SESSION["firstname"] = $user_info['firstname'];
$_SESSION["lastname"] = $user_info['lastname'];
$_SESSION["screen_name"] = $user_info['screen_name'];
$_SESSION["facebook"] = $user_info['facebook'];
$_SESSION["email"] = $user_info['email'];
$_SESSION["date_joined"] = $user_info['date_joined'];
$_SESSION["account_type"] = $user_info['account_type'];
$_SESSION["account_active"] = $user_info['account_active'];
$_SESSION["hashed_password"] = $user_info['hashed_password'];
问题是,如果他们从www.domain.com登录然后最终登录domain.com上的页面,或者反过来他们从domain.com登录并最终登录www.domain.com页面存储在会话中的信息不可用。
无论是否使用www登录,我如何才能获得会话信息?

做这样的事情是否合适:
<?php
//Ok I modified the code so I don't get the undefined errors I was getting
//OLD CODE
//$currentCookieParams = session_get_cookie_params();
//$rootDomain = '.domain.com';
//session_set_cookie_params(
//$currentCookieParams["3600"],
//$currentCookieParams["/"],
//$rootDomain,
//$currentCookieParams["false"],
//$currentCookieParams["false"]
//);
//session_name('mysessionname');
//NEW CODE
$rootDomain = '.beckerfamily1.com';
session_set_cookie_params( 3600, '/', $rootDomain, false, false);
session_start();
if (isset($_SESSION['LAST_ACTIVITY']) && (time() - $_SESSION['LAST_ACTIVITY'] > 2700)) {
// last request was more than 45 min ago
if(isset($_SESSION['id'])){
$connection = mysql_connect('localhost', '******', '*******');
if (!$connection){
die('Database connection failed: ' . mysql_error());
}
$db_select = mysql_select_db('beckerfamily');
if(!$db_select){
die('Could not select database: ' . mysql_error());
}
$query = "UPDATE users SET online='no' WHERE id='{$_SESSION['id']}' LIMIT 1";
$result = mysql_query($query);
if (!$result) {
die("Database query failed: " . mysql_error());
}
}
$_SESSION = array();
if(isset($_COOKIE[session_name()])) {
setcookie(session_name(), '', time()-42000, '/');
}
session_destroy(); // destroy session data in storage
session_unset(); // unset $_SESSION variable for the runtime
if(isset($connection)){
mysql_close($connection);
}
}
$_SESSION['LAST_ACTIVITY'] = time(); // update last activity time stamp
?>
是否有必要使用session_name('mysessionname');
或者我可以省略它,PHP会自行设置会话名称?
答案 0 :(得分:1)
Cookie(如PHPSESSID Cookie)仅适用于其设置的域。您可以使域包含所有子域:
ini_set('session.cookie_domain', '.example.com' );
或者如果配置不允许您覆盖它,
$currentCookieParams = session_get_cookie_params();
$rootDomain = '.example.com';
session_set_cookie_params(
$currentCookieParams["lifetime"],
$currentCookieParams["path"],
$rootDomain,
$currentCookieParams["secure"],
$currentCookieParams["httponly"]
);
session_name('mysessionname');
session_start();

更好的方法是选择是否要通过www
访问您的网站,并将所有请求重定向到另一个。

我不确定您使用的是哪种语言,但您需要更改会话Cookie的“域”属性。如果您将cookie域设置为“domain.com”,则可以在“domain.com”和“www.domain.com”上访问它。
