facebook connect Fb.getLoginStatus from php-sdk

I’m building an app with multiple subdomain for my users, since the Facebook JS SDK don’t allow wildcard on Authorized domains for the JavaScript SDK in App settings, I created an auth.example.com where I can authorize users with the php-sdk and save token in db I’m wondering if there is a way I can use the JS SDK with the access token from server-side, to be able to use the different methods of the JS SDK Such as FB.getLoginStatus, FB.login, FB.logout …, I tried to create the same cookie from the server-side but the php-sdk doesn’t return the signed request Any suggestions ?
