Examples in $_SESSION's needed

[Anon]

I am trying to fully understand how to rewrite a lot of code to work on PHP-4.1.2 with globals off.

I have yet to find any examples, most use globlas switched on.

Does anyone know of the whereabouts of an mini program example, a few lines does not give me much of a clue.

A couple of immediate queries are:-

Should you use session_start() within every function?

In my config, I define
$_SESSION['new_window_width'] = 400;

instead of $new_window_width = 400;

However, when called within a Javascript coded script it does not appear to read what it had read before.

Where am I going wrong??

Any help with the new way of coding would be very much appreciated.

Thanks.

I'm just getting into sessions myself, but one thing I can tell you is that session_start() needs to be called on every page that uses sessions, and needs to be the first thing called, before any HTML or any other PHP.
