I am using session variables to store data

I am trying to store 4 or 5 variables but seem to only end up with 1 value in the session file

I have attached the session class, some session files and my php.ini
The total contents of a session file where the last thing I set was the the username

$varname|s:8:"johnec50";

The total contents of a session file where the last thing I set was the the user role

$varname|s:5:"Admin";

The total contents of a session file where the last thing I set was the value of "yes" for  a variable called auth

$varname|s:3:"yes";

It looks like the variables overwrite themselves  

Please if you can help


Thanks for reading this

try replacing the line
$_SESSION['$varname'] = $value;
with
$_SESSION[$varname] = $value;

inside your class

As implemented, the literal string $varname, not the variable contained in $varname, has become the key into the session array.  Note the different ways of defining strings in PHP.  Please read this page carefully to understand the difference that arises when you use single quotes.
http://php.net/manual/en/language.types.string.php

Also, it looks like the information in the session has been serialized and I do not know of a good design pattern that would include doing that.  The session uses an array named $_SESSION.  Here is everything you need to do to use the session:

<?php
session_start();
$_SESSION["john"] = "collins";
var_dump($_SESSION);
