$_SESSION has gone crazy

[magic-chef]

I am no longer amused...

It seems the session vars on my computer have gone off the deep end!!!

I wrote scripts last night that DO NOT WORK today even though they worked last evening. This is all related to sessions and their variables.

For some reason the vars cease to exist.

I can go to one page and set the variable in a session. Redirect to another page and the session var is not there. This is really getting to me.

I am wasting time working on one item. Once the problem seems to be solved I start something else. Come back several hours later and nothing works. I post the code to this site and either no one responds or someone tells me it should work.

Is there some tricks to working with sessions?
Are there bugs with session variables?
Why would a session variable be available on one page in the site and not exist on the next page (I start every page with a session-start())?
What is the best way to reference a session variable?
What is the best way to assign a value to a session variable?

I could keep going but perhaps someone will have an answer to my problem. It has been ongoing for two days now.

I assume by session-start() you actually mean session_start().

Sessions work fine for me.

page1.php

<?
session_start();
if(!session_is_registered('user'))
{
session_register('user');
$_SESSION['user'] = 'Bob';
}

echo $_SESSION['user'];
?>

page2.php

<?
session_start();
if(!session_is_registered('user'))
{
echo "user is not registered";
}
else
{
echo  $_SESSION['user'];
}
?>

Yep, it was a typo.

This relates to tracking states across several pages. The state connot be assigned on another page.

I have several examples of code submitted earlier (see my user name). I checked them resolved since they initially appeared to be.

It does not work for me!
