very basic: session_start();

14/06/2008, 17h56

If there are better places for basic questions like this, feel free to
redirect me.

Say I have a php page with session_start(); I can assign variables and
those variables will carry over to other pages in order to use them in
those other pages, right? e.g. fname and thus $fname. Let's also
assume I am not assigning Global variables within any of the code.

But, if by chance one of those 'other' pages ALSO begins with a
session_start(); does that close the first session and throw away its
variables, making them no longer available from 'other' pages?
Is the above what the line $_SESSION['views']=n; is intended to
accomodate?
e.g.:

<?php
session_start();
// store session data
$_SESSION['views']=1;
?>
<html>
<body>

Does that then allow me, from any page, to call whichever set of
variables I want/need for that particular page by retrieving a 'views'
set?

I'm trying to work it our programatically but it's a little confusing
without some verification from the 'ones that know' if you will.

TIA

No, not $fname, $_SESSION['fname'].

Doesn't matter.

_every_ page that uses a session has to call session_start() (before any
output) to be able to use the $_SESSION array.

Nope, it continues the session.

It just sets a variable in the session array.

You can only retrieve what you have set in the $_SESSION array. What do
you mean with a 'views set'?

using session_start() on a script - if there is no session it sets
one up; if there is a session, it opens it. If you wait too long
between pages it disposes the session automatically (set time for
session to keep alive in php.ini).

You need session_start() on all pages that needs to access the
$_SESSION array.

$_SESSION is just like an array variable, so if you want to segregate
data you could set a sub array of page data in $_SESSION...

$_SESSION['views'][1] = ...array of data...;

Hope that s

OK, that s a LOT, Rik!
By "vews set" I meant something totally irrelevant; I thought a "set"
would be, for instance, a 'set' of variables contained in
$_SESSION['views']=1 , then another, different set would be contained in
.... =2, and so on. I kind of caught on some when I came across a PHP
page counter but ... .

%_SESSION is the piece I've been missing out on; don't recall coming
across it before, but that doesn't mean much. I'm still learning to
find my way around the w3schools heriarchies.

Thanks much!

Ha! I think that might explain a couple of "strange" events that happen
when I go away and come back later! If I read that right, it's only
about 24 minutes (1440 S). I'm not going to change it because I don't
know the nuances/inter-plays of the php.ini yet. I'm perfectly happy
just knowing there's a reason for it! I've been getting ready to blame
the OS.

I think I'm starting to catch on; for whatever reason I've been totally
misinterpreting some of these things including $_SESSION. It's always
hardest for me to get the basics into my head when I start something new
like this.

Thanks much

WHY dontÂ´t you read the PHP Manual?
Everything is described. Sessions too.

Sometimes it's a lot more simpler then you realize.

How to use arrays is a big part of making some cool PHP stuff,
especially how to handle them in form data and in $_SESSION. It's
taken me a while to wrap my brain around it too, but its worth it.

I assume you mean php.net's; not only read it, reread it, reread it, and
then reread it again. w3schools is pretty decent stuff.
