The only rule is that you need to call session_start() before any output
is sent to the browser.
You can accomplish this by either making sure that your script won't
echo/print any data (and won't print notices, warnings, etc) before
session_start() is called, or you can turn on output buffering (so make
your first line ob_start(), or set it up via configs), so all output is
buffered on the server until the script completes.

Hello all,
I have a class that handles session and that is included further down
in the class.
Typically file struct:
PHP
Config (dev, live, etc)
Includes
Instantiate classes (session_start( ) gets called in the session
objects constructor)
Support functions
Main code, usually in the form of a switch( ) on a GET/POST var
Debug data (db/script execution time, etc.)
</PHP
Works great for me.

** I want to get rid of this meaage when I locad the php web page.
How to do it?
I found that session_start() works only OK when it is the first thing
that happens in a script. Before initializing variables and anything.
You script should start as such
<?php // Line 1
session_strt(); // Line 2
....everything else
I follow that strictly and since then never had a problem.
