Changed cookie domain, but old cookie is still used - php

EDITED, look at the end
I got a Symfony 1.2 project, that was running on two domains (different app used on each domain) : www.mywebsite.com and abonnement.mywebsite.com
I had two different cookie name/domain in each app.
We decided to use the same cookie for both apps. So, i edited the config for both apps and set the cookie_domain to .mywebsite.com, and setted the cookie_name to mywebsite_cookie in boths apps.
The problem is that when I visit abonnement.mywebsite.com, the old cookie is used. Manually deleting this cookie in my browser fixes the problem, but there are thousands of users on this website and I'm wondering if there's a solution to manually delete this cookie.
I tried :
if (isset($_COOKIE['abonnement_cookie'])) {
ini_set('session.cookie_domain', 'abonnement.mywebsite.com);
setcookie('abonnement_cookie', '', time() - 3600, '/');
$this->redirect('#internet_etape_1');
}
But no success.
Is there a way to do it?
I'm using Firefox 9.0.1
Thanks!
Edit:
I found the problem, cookie was created with "host" and not "domain".
To use the current host, you need to specify '' as domain :
setcookie('abonnement_cookie', 0, time() - 3600, '/', '');
Hope this helps!

You need to match the domain and path that which was used to create the cookie when destroying the cookie. This is because as you have discovered, it is possible to have a cookie with the same name and different scopes for the same domain. When destroying the cookie, you must match the scope that was used to create it, so the client knows which one to destroy.
Try:
setcookie('abonnement_cookie', '', time() - 3600, '/', 'abonnement.mywebsite.com');

How to read cookie from subdomain in PHP?

Can anyone tell me how to read cookie from subdomain. I can set the cookie for subdomain but unable to read it.
Please tell me what is the syntax in PHP to read cookie from subdomain.
If you're enabled to read in other subdomain, it's probably because you didn't properly set the cookie to begin with.
$date_of_expiry=time()+ 3600;
setcookie( "cookie_name", "cookie_value", $date_of_expiry, "/", "example.com" );
It's important that you put the last argument for the cookie to be available in other subdomains.
Also, the cookies must be set before page output.

Migrate cookie domain from no domain to .mydomain.com with PHP/Nginx

I have a web site wrote with PHP and running on Nginx HTTP server. I have a cookie called "locale" which represents the user locale. For 6 months, I am sending the cookie like this:
setCookie("locale", "fr", time() + 36000, "/");
As a cookie less domain, I understand it's only available on my single domain "www.mydomain.com".
But now, I want to create 2 news sub domains:
m.mydomain.com (the mobile part)
secure.mydomain.com (a secure version)
I see "locale" cookie set on www is not accessible by m or secure. So now I am sending the cookie like this:
setCookie("locale", "fr", time() + 36000, "/", ".mydomain.com");
Yeah my cookie is available everywhere now! But as I have some users who had already browsed my web site, they have the domain less cookie + the new one, their browser send me both cookies but PHP gives me the former one. As a result nobody can change the locale any more.
Question is: how can I migrate from this domain less cookie to a domain specified cookie? Without change the cookie name.
The first cookie you set without the domain defaulted to www.mydomain.com and because that's more specific than '.mydomain.com' it's choosing the original cookie. Read the accepted answer here.
How to get the domain of a specific cookie?
As conclusion, I will put this in my index.php file during 1 week:
setCookie('locale', null, time() - 5000, '/');
In order to delete the domain-less cookie. I have tested on all major browser, and I don't see any conflict with:
setCookie('locale', 'fr', time() + 36000, '/', '.mydomain.com');

setcookie from subdomain to domain

I have:
mydomain.com (which is the portal of the game, global setting and stuff)
game.mydomain.com (which is the the actual game)
The problem is that I want to set a cookie that is available globally, on game.mydomain.net, mydomain.net (and whatever subdomain i'm going to create in the future).
I've been trying to set the cookie from another subdomain as I've read that subdomains can set cookies to parent domains but not vice versa (which is wierd and I guess I've read it wrong). Whatever, so I've done another account.mydomain.com (from which I'm making an ajax call form mydomain.net so the user can authenticate) and I'm using
setcookie('session', $value, time() + 2592000 (one month), '/', '.tribul.net');
Then, return the success message and refresh the main page on mydomain.net so it can read the new cookie value.. problem is, there's no cookie set. I've also been trying to set the cookie from mydomain.com (as .tribul.net) so it can be avaialable on all subdomains but it's available only on the main domain. What's wrong?
I need to connect all subdomains and the domain to the same cookie, TO BE NOTICED, I am setting the cookie in a backend file named process.php (placed in account.domain.com) as result of an ajax request.
Try this setcookie('session', $value, time() + 2592000 , '', '.tribul.net');
In php.ini:
session.cookie_path = /
session.cookie_domain = ".mydomain.com"
Set Cookie:
setcookie('session', $value, time() + 2592000, '/', 'mydomain.com');
I used Klaus Hartl's jquery cookie plugin in order to use my problem since I haven't been able to set up a global cookie from the ajax backend.

Session cookies working under subdomain

How to get session cookies working / to be accessible under domain and subdomains?
For session cookies you need to override the cookie params:
So you can either use:
ini_set('session.cookie_domain', '.website.com');
or
session_set_cookie_params(0, '/', '.website.com');
The '.' in front makes it accessible under the domain and the subdomains.
Note: you will have to delete all existing cookies from your browser for the domain you're working with so they can be re-initialized properly to work.
If you set the cookie for the "top" domain (example.com), the cookie will also apply to subdomains (sub.example.com, another.example.com).
As an aside, this is the reason why some larger companies use completely separate domains to serve static stuff, like stackoverflow uses http://sstatic.net/
I'm assuming you are using setcookie(). If so just set the cookie for ".domain.com".
setcookie("testcookie", "1", 0, "", ".domain.com");

Setting cookie path to "/" does not make cookie accessible to entire site

Why when set php cookie path to "/" doesn't work for every subdirs in the domain, but just for the current directory.
cookie is set like:
setcookie("name", "val", expire_time, "/");
It just doesn't want to work.
try including the domain parameter:
setcookie("name", "val", expire_time, "/", ".domain.com");
// don't forget the prefixing period: .domain.com
that will enable all sudomains of "domain.com"
Are you testing on localhost? In that case, you need to pass null as the value for $domain.
Setting the cookie path to / should make it available to the entire domain. If you set your cookie like that, and it isn't being sent, there is something else wrong.
Try using the Web Developer addon in Firefox. It shows you details on the available cookies. Maybe that can help you diagnose the problem.
Late to the party, I know. But I just discovered that my issue was pretty stupid, but I'll post it for completion:
I was neglecting to add time() to the expires time on the cookie, so it was expiring immediately.
The expires time should be time() + seconds
