Title: Fix reference to $session->set/get typo on p.21

On page 21 of the PDF it reads:

```php
// use a default value if the key doesn't exist
$filters = $session->set('filters', array());
```

It appears that the `$session->set` here should be a `$session->get`. This PR would change it to read:
```php
// use a default value if the key doesn't exist
$filters = $session->get('filters', array());
```
