In that case there are only two options. Either the second page didn't
call session_start() before any output, or the third page didn't do it.

Sessions work. If the second page properly starts the session and sets
the session info, and the third page properly starts the session, it
does work.

I know this sounds blunt - and I'm really sorry, I don't mean to be
blunt about it. But sessions do work. If you have a case where the
second page sets a session variable and the third page can't read it,
one of two things is wrong:

1. The second page didn't actually set the $_SESSION value in the
session (possibly because session_start wasn't called early enough - but
there could be other reasons), or
2. The third page can't read the $_SESSION value. In this case if it
is set, about the only option you have is that session_start() wasn't
called soon enough.

So, if the third page (where the value is read) is correct, perhaps the
second page (where it is set) has a problem?

It's got to be one or the other.
