  • 0

I have a Symfony2 app and I have to read the sessions set from another, non-symfony app.

The non-symfony app just set its sessions into $_SESSION, as usual.

However, when I attempt to read this session, the data isn’t there. No matter I do it by 

$session = $this->get('request')->getSession();
var_dump($session->all());

or even (I know I shouldn’t do this, but anyway)

var_dump($_SESSION);

and this gives me session already started error, and I have no idea why there is error despite I have never started session in the Symfony app. Tells me if this way actually work so that I can look into session_start() thing.

$session = new Session();
$session->start();
var_dump($session->all());

The PHPSESSID cookie is set in the Symfony2 app and its value is the same as the cookie set in the non-symfony app, but my Symfony2 app just refuse to read the content of the session. ($session->getName() returns PHPSESSID, to be clear)

(To be exact, both apps are under same domain but different subdomains, and I have already set framework.session.domain correctly in app/config.yml in Symfony app and called session_set_cookie_params on the non-symfony app to have the same domain setting to allow sharing session cookie between subdomains i.e. .example.com)

So how do you read sessions in a Symfony2 app/Controller that is set by a non-symfony app? Thanks.

I am using Symfony 2.1, if this matters.

    You won’t be able to use the native Symfony2 session wrapper classes because they read session data from app/cache/{env}/sessions/{session_id}, and your non-Symfony2 app isn’t writing its session data to that location.

    You could write a custom session handler in your non-Symfony2 app that writes to that location, or better still you could write a native session handler class in Symfony2 which bypasses the default Symfony2 session read location and gets it from the default PHP session path

    EDIT: Since writing this answer there is now a much more elegant solution available in gadbout’s post below.
