Facebook API: How to let the php knows whether the user is a fan of the application or not?

Plan 1: failed is displayed at the html level only.. .it won't let the php level knows whether the user is a fan or not

Plan 2: failed has got the same problem too

Plan 3: failed fql permission table simply lacked the field of is_fan http://wiki.developers.facebook.com/index.php/Permissions_%28FQL%29

Plan 4: server lag calling restful API http://wiki.developers.facebook.com/index.php/Pages.isFan will bring a lot of lag to server... and I wonder if it can works on application page too.

any suggestion to solve this problem?
