What are the potential pitfalls of passing objects between PHP forms?

One potential pitfall of passing objects between PHP forms is the risk of exposing sensitive data or causing unexpected behavior if the object is modified in an unintended way. To solve this issue, it is recommended to serialize the object before passing it and then unserialize it on the receiving form to ensure data integrity. 

// Serialize the object before passing it to another form
$serializedObject = serialize($object);

// Pass the serialized object to another form using a hidden input field
echo '<input type="hidden" name="serializedObject" value="' . htmlspecialchars($serializedObject) . '">';

// On the receiving form, unserialize the object
$object = unserialize($_POST['serializedObject']);
