Is there anyway to prevent session variables from being overwritten by a get string?
I'm wanting to use sessions for security/login, but I'm finding that I can bypass this
very easily. For example, I want to hide menu items based on security level, so I use
something like this:

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 = ;
If you do this, then session

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
When does a session variable become available? Immediately after the
session_register command or after the script ends?
And if the commands are as follows:
session_start();
session_register(hello);
$hello=3;
will the session variable $hello be set to 3 or do I have to add another

Immediately after it is assigned.
And if the commands are as follows:
session_start();

session values from script 1 before they can be retrieved by script 2.

so the session variable is set only when the script ends? I
thought you
indicated that they were set immediately...
Thanks for the quick reply,

I've tried to follow the example in the online manual, but and I believe my
session/cookie variables are being stored. Is there some specific way I need
to call them? Can anyone provide a brief example?
Thanks.

I tried using a cookie I still had the same problem that it worked first
time but even if you stayed on the page and put a sencond entry in it
would
not work,
then you:
set the cookie incorrectly
overwrite/delete the cookie by mistake
your browser does not support cookies

I am using a session to store a variable so when someone enters something
into a field the persons username(which is stored in the session) is also
entered into anoter field.
The problem is that it only works the first time, so how can I make the
session last for a required length of time, so

Hello,
is it meant that
session_register("test");
$GLOBALS['HTTP_SESSION_VARS']['test'] = 'Hello World!';
does not work properly (session variable test is not initialized with the
value 'Hello World!') if register_globals is turned on, but when it is
turned off?
Best regards

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?
