How to get the logged in member id from PHP / hooks?

Question

Is there a hook-independent way to get the logged in member id inside a hook handler?

Something like a function or a global variable?

Answer 1

Yip. You're looking for:

ee()->session->userdata('member_id');

It's in the session class:
