PHP会话在不同的文件夹

Question

Problem PHP session in different folder.

I have problem with PHP session.

There are two folder: A AND B When I already logged in Folder A then i click link access to folder B when come to index.php file in Folder A. It doesn't to recognize session state.

PHP Code:

if(!isset($_SESSION))
{   
    session_cache_expire (21900);
    $cache_expire = session_cache_expire();  
    session_start();
}

How can i check session redirect ?

f(!isset($_SESSION['a'])){
    redirce to a
}

f(!isset($_SESSION['b'])){
    redirce to b
}

Best Regards

Answer 1

Try this:

if(!session_id()) {
    session_start();
    session_cache_expire (21900);
}

Check your phpinfo() and look for suhosin. If it is installed then you should disable it in order to let sessions be shared betwen different paths.

Answer 3

This is happening because the validity scope of the PHPSESSIONID cookie is restricted to the folder A , so in folder B it doesn't get fed the same cookies. You have to change that to the parent folder containing both A and B .
