PHP – Save an object as a session variable?

Saving the state of an object to your session can be very useful, and can be accomplished by using a combination of the serialize/unserialize functions.

class.php

<?php
class warebot

{ //class implementation

function warebot(){}
}
?>

class.php has our simple class definition/implementation.

page1.php

<?php

session_start();

require_once('class.php');

$object = new warebot();

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

?>

page1.php is where we will create the object, serialize it and save the serialized result to our session
page2.php

<?session_start();

require_once('class.php');

$object = unserialize($_SESSION['object']);

?>

page2.php is where we will unserialize the previously serialized object (saved in our session)

Voila! you know have complete access to your original object.
