Question

Answer 1

There is no such term infinite session keys. But you can ask user to give you offline access extended permission. If user approved the permission, then you can save the session key and later user.

If you use new php sdk, then you'll find there is a method $facebook->setSession($session); You've to pass users's stored session to here.
