the PHP Manual says
" ... Note: If you are using cookie-based sessions, you must call
session_start() before anything is output to the browser.
"
the nature of sesion mechanism is more complex than just cookie. You can
set cookie at any place of script - you just make easy operation - write
the information to broweser's cookie. When session starts it uses cookie
only to save session identificator but behind the curtains huge piece of
work being done - session prepares the, so called, session environment. I
have never dig it deeply though :)
Let mne know if this helped.
