I've faced a strange issue with session across subdomain only for google chrome.
I have two subdomain a.mydomain.com & b.mydomain.com.
if I open a.mydomain.com first on browser & then open b.mydomain.com & login from there then I'm not getting the session in a.mydomain.com. But if I login first from b.mydomain.co & then open a.mydomain.com I'm getting the session in a.mydomain.com.
I'm unable to solve this. Please help
silly me, found the answer so liked to share it
I used session.cookie_domain only for b.mydomain.com & not for a.mydomain.com
Look at the session cookies in your browser. What are the domain settings on them? Possibly your sites have different cookie settings. where the a site is setting a .mydomain.com cookie, and the b site is setting b.mydomain.com, prevent the cookie from appear on site a.
Cookies will only be inherited when setting them on the domain one level above. Setting the cookie on example.com will inherit it to www.example.com, foo.example.com, etc.
Setting a cookie on www.example.com will not show the cookie to foo.example.com.

I have edited session.cookie_domain = ".mysite.in" in php.ini to share one single session for same user across all the sub domains of my site.
But it is not working weird. Now if I open a session at "www.mysite.in", it gets shared with "mysite.in"(no www), but not with "oth.mysite.in".
PS : The session did not get shared to "mysite.in" before. So edit definitely has some effect.
I have a problem sharing the session between two subdomains, and I've read a lot of threads here and other places.
I have www.xx.com and sub.xx.com and I've set
session_name("PHPSESSXX");
session_set_cookie_params(0, '/', '.xx.com');
and the session.save_path is the same on both domains.
I get a cookie called PHPSESSXX on both domains, and it has the same value.
When I log on to www.xx.com I get a session with some details in it, and it stays that way until I go to sub.xx.com. Then the session on sub.xx.com is empty, and if I refresh www.xx.com, the session there is gone as well. So it does something, but it seems to be overwriting the session data each time I visit a different subdomain.
Any ideas anyone? - Can i debug this somehow?
Btw: I'm using ssl on both domains.
cheers
PHP session ids are saved in Cookies. To make a cookie available in all the sub-domains you need to assign it to the root domain. Then all the sub-domains will get the session id from cookie and PHP can find the session using passed session id.
As it turns out, You just need to set the session.cookie_domain to the root domain in php.ini file
session.cookie_domain = ".example.com"
Also check manual for different approaches used to set an ini entry.
Your question is answered here
Sharing SESSION Variables Between Multiple Subdomains
My solution was to set a flag in .htaccess like this:
php_flag "suhosin.session.cryptdocroot" 0
And it now works perfectly ;o)
The problem was that Suhosin was installed on the system, and the ini variable
suhosin.session.cryptdocroot = On
encrypted the session files in such a way, that when a different subdomain tried to change the session, it deleted everything for security reasons.
It didn't work for me to set the variable to Off or [nothing] in the ini-file, though maybe I didn't find the right file.
I also tried setting it in PHP without any luck. Like this:
ini_set('suhosin.session.cryptdocroot', 0)

We are having some issues with PHP Session Cookies not allowing us to log into our *SugarCRM** application which is open source PHP application.
The problem is we have the same application installed on 2 sub-domains like below...
Main site
www.domain.com
Dev site
dev.www.domain.com
Now after logging into one, it will not allow you to login to the other!
Please view the image below to see the Cookie problem...
In the image above you can see that there is 2 PHPSESSID Cookies competing for the Session!
If I now delete one of them, it allows me to login as normal without an issue!
Because this is SugarCRM, I am hoping I can resolve this issue without making really any core file modifications to the application. But if I have to, then we will.
So does anyone have any ideas on a good solution?
Right now my idea for a "Nasty Dirty Hack" which I really do NOT want to have to do. It is to make a button on the login form, this button will use JavaScript to clear/delete the PHPSESSID Cookies but again I would really like to find a proper solution.
If anyone has any ideas, please share? Thank you
UPDATE
Thanks for the answers so far. Please do take into acocunt that this is not a simple PHP application that I built where I can easily do code changes. THis is SugarCRM which is a massive large application with thousands of files
Try to setup in .htaccess parameter on subdomain
php_value session.cookie_domain .domain.com
or use in php code, but before "session_start()"
ini_set('session.cookie_domain', '.domain.com' );
Use
session_set_cookie_params
to set the session from the subdomain, on the principal domain.
Try to use function (http://php.net/manual/en/function.session-set-cookie-params.php):
session_set_cookie_params ( $lifetime, $path, $domain, $secure, $httponly)
And set one $domain = '.domain.com'
Or if you setting session cookie manually by setcookie, then setting the same domain too
Its actually not the domain you need to change, but the "session name" (name of the cookie parameter). Both apps seem to be using the default "phpsessid" and need to be made to differ, otherwise the apps will see eachother sessions, see the wrong session, or try to unserialize classes only defined in the other project.
You need to change the cookie parameter its storing the session ID in. It can be controlled from an environment variable (php.ini, .htaccess, etc.): http://us1.php.net/manual/en/session.configuration.php#ini.session.name
This way you can have multiple PHP sessions on the same domain. For example if you had example.com/sugarcrm and example.com/foo You could have sugarCRM store it's session ID in a cookie param called "sugarsession" (instead of the default phpsessid)
It has been a while since I had this issue but I think all you have to do is write each instances session file to a different directory by editing the config.php in each SugarCRM's file system and change the line
'session_dir' => '',
to point at a different directory.
I cannot access cookies from any page other than the page they are set on. I looked at print_r($_COOKIE) on different pages and the only common variable between pages is the $_COOKIE['PHPSESSID'].
I am developing on a local XAMPP testing server. Is there a setting I should change on the PHP.ini or is this normal behavior for cookies? Sorry, I'm a little new to this stuff and I was under the impression cookies were accessible site wide.
I am setting cookies like:
setcookie("user", "Dave Schmave", time()+60*60*24*120);
Any help would be greatly appreciated. Thanks
Try setting the cookie path to the root:
setcookie("user", "Dave Schmave", time()+60*60*24*120, '/');
Also is it on the same domain? Accessing via HTTPS will also affect your cookies.
I am developing a site on my localhost, where everything works fine, but now that the site is uploaded to the HTTPS side of our inserted ONLINE /inserted server, the $_SESSION variables don't get carried over from the login.php to the index.php page. Both are located on HTTPS, the process never goes out of HTTPS. As I said, everything worked fine on my localhost.
My localhost's PHP is version 5.3.2 and the HTTPS server is 5.2.6. The only difference in settings I can identify regarding sessions is session.use_only_cookies is On on my localhost and Off on the HTTPS server.
Can anyone please shed some light as to why the session variables are not transferred? PS. I do have session_start(); in both login.php and index.php.
Thanks in advance.
Have you checked that the session cookie is carried over between the HTTP and HTTPS requests? And that the same session token is present on both sides?
If the cookie established via the HTTPS page is marked as "secure only", it will not be transmitted to non-SSL pages, so you'd get a brand new empty session on the non-secure pages, which would give you the symptoms of "missing" session variables. They're not really missing, just in some other session which isn't active now.
There are a few things that can go wrong.
Make sure both login.php and index.php are accessed through https. session.cookie_secure defaults to off, but you never know.
Also make sure they are they both on the same domain. Cookies are set per-domain.
Maybe there is some oddball cookie setting? You can view the current session cookie settings with: session_get_cookie_params()
You can also verify how the cookie is being set in your browser (if at all), for Opera you can right-click in the page, select "edit site preferences", and use the "Cookie" tab. Don't know about other browsers from the top of my head ...
Another possibility is a borked session.save_path, run session_save_path() without any arguments to get the current session_save_path, make sure the user running PHP (typically but not necessarily the same user running the webserver) can write to this directory.
