<?php

if(!isSet($_SESSION['vars'])){
  $vars = array();
  $vars['name'] = $name;
  $vars['email'] = $email;

what does the vars = $array(); do?

[kevinsequeira]

$vars = array(); create a array called vars.
the reason i did it was so that all your variables can be accessed easily through that array.
u could do it this way too without the array

<?php
  session_start();
  $_SESSION['name'] = $name;
  $_SESSION['email'] = $email;
  $_SESSION['ok'] = $ok;
  print_r($_SESSION);
?>

I'm sorry to be a pest.. But what is the best way to store this information or retrieve from the next page? I'm attempting to pass these variables across 3 pages.

Thank you for your time and help

simple example

<?php
//page1.php
//declare the variables or get them from a $_GET or $_POST
$name = "pinehead18";
$email = "[e-mail]";
$ok = "yes";

// initialize the session variables
session_start();
if(!isSet($_SESSION['vars'])){
	// if its not set, create a new array to hold its values
	$vars = array();
	$vars['name'] = $name;
	$vars['email'] = $email;
	$vars['ok'] = $ok;
}
$_SESSION['vars'] = $vars;
echo "<a href=\"page2.php\">goto page 2</a>";
?>

<?php
//page2.php
session_start();
	$vars = $_SESSION['vars'];
	$_SESSION['vars'] = $vars;
echo "<a href=\"page3.php\">goto page 3</a>";
?>

<?php
//page3.php
	session_start();
	print_r($_SESSION['vars'])
?>

How do i pull the indivudual variables out of $var?

like th e$name and what not... So i can define them on the last page?

[kevinsequeira]

the way you print out variables in an array.

1. either loop through the array
   <?php
   //page3.php
   session_start();
   $vars = $_SESSION['vars'];
   foreach($vars as $key=>$value){
   echo $key." is ".$value."<BR>";
   }
   ?>

2. echo indivdual elements out if you know their name

<?php
//page3.php
session_start();
$vars = $_SESSION['vars'];
echo $vars['name']."<BR>";
echo $vars['email']."<BR>";
echo $vars['ok']."<BR>";
?>
