Storing objects inside a session

I am attempting to store an object into $_SESSION but I am having a few issues doing so.

Here is the class:

class Profile {
            var $username;
            var $password;
            var $admin;

            function __construct($username, $password) {
                $this->username = $username;
                $this->password = $password;
            }

            function getName() {
                return $this->username;
            }

            function isAdmin() {
                return $this->admin;
            }

            function setAdmin($admin) {
                return $this->admin = $admin;
            }
        }

and I am storing the data inside the session this way:

$_SESSION['profile'] = serialize($profile);

and when I attempt to load that data in another class I receive an error:

Fatal error: main(): The script tried to execute a method or access a property of an incomplete object. Please ensure that the class definition "Profile" of the object you are trying to operate on was loaded before unserialize() gets called or provide a __autoload() function to load the class definition in C:\wamp64\www\login\hidden.php on line 33

I have dumped the loaded object to check if it is actually being loaded and it appears the object has been unserialized and I can see all the data itself inside the object.

$profile = unserialize($_SESSION['profile']);
var_dump($profile);

and I receive this on my localhost when dumping it:

C:\wamp64\www\login\hidden.php:31:
object(__PHP_Incomplete_Class)[1]
  public '__PHP_Incomplete_Class_Name' => string 'Profile' (length=7)
  public 'username' => string 'myles' (length=5)
  public 'password' => string 'myles' (length=5)
  public 'admin' => boolean true

I am truly lost and have no idea what to do if someone could help me, that would be great.

Before unserializing you need to do the same thing you would before creating an instance of the object normally:

$profile = new Profile("u", "p");

That is, make sure you have included all the files that define that class. That is what the error message is trying to tell you:

Please ensure that the class definition "Profile" of the object you are trying to operate on was loaded before unserialize() gets called

So do something like this:

<?php
require_once '/path/to/Profile.class.php';
session_start();
$profile = unserialize($_SESSION['profile']);
