This script creates the familiar Car class containing some fixed public properties — $manufacturer ,

$model , and $color — and also adds a private array property, $_extraData . The Car class
also contains a __get() method that looks up the requested property name in the keys of the
$_extraData array, returning the corresponding value in the array (if found). The corresponding __set()
method takes the supplied property name and value, and stores the value in the $_extraData array,
keyed by the property name.
