Ok i have got a problem.
I want to use php4 sessions
and i have the book beginning php4
but it doesn't tell you how to use sessions very well.

So, if i got a form, on say test.php which asks then user to type anything and it puts it into a varialbe called $example and then moves to test2.php

how would i store the $example variable from the form on tast.php into a new session???

also, say for example, i then had a link on test2.php that moves the user to test3.php, how do i get the data back from the session and display the data from the form, on the screen using echo()???

if someone could explain this to me, then that would be great.

thanx allot

there are loads and loads of sessions examples.. type "php sessions tutorial" into google, thats how i learnt.

<?
session_start();

if(session_is_registered('password'))
{

// Session Already Registered Display Content

} else {

// Register Session
if(!$example)
{
// Example Doesn't Exist
}
elseif($example == "password")
{

// Example = Password Register Session Variables
$password = $example;
session_register('password');
print "<A HREF=''>Click Here</A> to continue!";

}
}
?>

I think the preceeding code assumes that you register_globals on. Real hot topic in the PHP world about this, and the php guide reccomends that you turn them off.

With register globals off, you'll want to access session variables via $_SESSION["varname"] array instead.

There is a thread very similar to this here: http://www.webhostingtalk.com/showthread.php?s=&threadid=80876

Also, go to http://www.php.net, for a discussion on register_globals, session variables and comments from php developers using the tool.
