Sessions variable HELP please

[Richard Hulbert]

Hi

Can Someone tell me why This doesn¹t work:
Page 1

$_SESSION['composer'] = 'A non';

Page 2

Echo $_SESSION['composer'];

( I get undefined variable)

I am developing on version 4.2.3

I think I am missing something pretty fundamental here. Its driving me nuts.

Many thanks
Richard

do you have session_start() on the top of page 2 ?

No That Was it many thanks!
But I would like to understand what's going on why put this on page two and
not page 1
I thought Session_start() initialised the session so any Session Variables
are Reset - Obviously I'm Wrong but can you explain?

Many many thanks for your time

session_start is to signify to support sessions. If there is no current
session data, it simply initializes the _SESSION array. If there is a
session in progress, it checks that it is valid, etc, then loads the
previous values into the _SESSION array.

You didn't need it on the first page beacuse assiging a value to an
element in _SESSION implicitly calls session_start first, then assigning
the value (at least when you haven't explicitly started the session).
