Hi There,
I am a beginner to PHP and I am tring to use session variables on my site.
I am trying to use Session Variables in PHP on the iPLANIT.tv site
When I use the following code:
I get the following error

I understand the concept of session variables, so I want to know the best
methodology of approaching this:
1) HTML redirect to PHP page
2) PHP page looks for session
a) If found, show some stuff
b) If not found, prompt user for username and password
3) If no session, prompt user for username
I am designing a form using sessions in which the user inputs their
details on page 1 and after submitting they are directed to page 2 for
confirmation. They then have the option of editing their input (ie they
are returned to page 1) where their previous input is reflected in the
form fields by

Is it ok to mail questions to this list? If so;
Is there something similar like the "session variables" of ASP in PHP,
or do one have
to use (client-side) cookies instead?

PHP will do this automatically *if* you initialize your session variables to
*anything* as soon as you register them. For example,
session_register("sess_auth");
$sess_auth = "";

Funnily - doesn't work for me. Here's what I got:
Script #1
#!/usr/local/bin/php
Script #2
#!/usr/local/bin/php
If I start script#1 (and it sleep()s), wait 10 seconds, then launch script
#2 in a separate browser window, script #2 returns empty. However once the
sleep() is completed and I refr
session values from script 1 before they can be retrieved by script 2.

Hello,
I have 3 scripts:

When I open http://host/i2.php on my browser I get 0, though I expect it
to be 4. If I uncomment session_unregister("counter"); I get 4 as
expected.
PHP version 4.1.2.
Anyone can explain this behavior? Also can anyone try this with sa

I've done this on other platforms ASP,Cold Fusion, but I need to know what's
the best way to do it on PHP.
1. grab username and password from POST vars.
2. select count(*) from users where username = '$username' and
password='$password'... something along these lines
3. if that user exists and pa
put this code in the home web page
$conn user online";
} else {
echo"$conn users online";
}
?>
and create this table in you db to hold the necesary values
#
# Table structure for table 'uonline'
#
CREATE TABLE `uonline` (
`caduc` int(15) NOT NULL default '0',
`ip` varchar(40) NOT NUL
I get '4', as expected, on v.4.0.6.

I have not tested this, but I do use sessions quite a bit. All session
variables are registered as global variables and therefore should be
available to other processes and

Okay, here is my dilemma:
I have one page, (non-secure), which sets session variables for the users
address, items, prices, etc. I have the next page which is secure, and
cannot get the session variables from the previous page. Is there a way to
pass the variables between the secure and non-secur

Hope someone can help on this one.
Say you have a FORM processing page that does lots of stuff, so it takes
many seconds to execute. Say the user gets impatient and hits the Refresh
button while the processing page is only half completed. Here's the
question: do any changes to session variables t
