@NogDogFeb 22.2005 — #The session ID gets transmitted from one page in the session to another. If you come into a session-controlled page from an "outside" page, a new browser session, etc.; then your session_start() will be creating a new session ID and will have no $_SESSION data associated with it yet. Also, session data normally has a relatively short lifespan, depending on you PHP installation settings (measured in a small number of hours).
So sessions let you share data between related PHP pages, but it is not intended for long-time, persistent data the way cookies can be.
The other alternative would be some sort of database solution based on the user's login ID (if you have one).
session issues (should be simple)
heres the code residing in a file on my server running apache 2 and php v 4.3.8:
(btw register globals is on, but as far as I understand it, that should not affect the code below)
[code=php]
<?php
session_start();
if(!isset($_SESSION[‘count’])) $_SESSION[‘count’]=1;
else $_SESSION[‘count’]++;
echo $_SESSION[‘count’];
?>
The intent, I hope, is obvious – everytime I reload or revisit the page, it should display a number incremented by one.
However – all I get is “1”. everytime. one one one … argh! This is important to me. Can anybody give me suggestions on where to start finding the source of these troubles?
Thanks!
EDIT: I thought I also should mention that I have tried adding: echo session_id(); at the bottom of the code, and my session ID is always the same, so I assume I have a live session, but the variable just wont seem to stick!

<?php
$visits = 1;
if(isset($_COOKIE['count']))
{
$visits = $_COOKIE['count'] + 1
}
echo "<p>This is visit number $visits.</p>n";
if(set_cookie('count', $visits, 60*60*24*365) !== TRUE)
{
echo "<p><i>Note: your browser did not allow me to set a cookie, ".
"so number of visits will always say '1'.</i></p>n";
}
?>
