Re: session_is_registered gets session values only after doing some output first !?

I try to check if a session is registered. This works fine if I first do some output echo "abc"; if (!session_is_registered('userid')) { do_something(); } else { redirect_to_somewhere(); } and I can't redirect to another page ... If I comment out the echo statement I get always false and $_SESSION is empty, but I could redirect somewhere... I tried php 4.3.1 and 4.3.7 with apache 2.0.45 both the same. On a Windows box the same program runs fine. Can anybody help? _________________________________________________________________________ Frank Rust, Technische Universität, Institut für Theoretische Informatik

You ought to make sure that the session was already started before trying to work with it. Either start the session implicitly via session.auto_start = 1 in your php.ini so a session is always started automatically or explicitly start it via session_start(). As long as the session is not started the session-array ($_SESSION, HTTP_SESSION_VARS) is not set.
