Then I have another class:

this is wrong. you can define the property in the class
with a constant or scalar value (i.e. literal string,
numeric value or an array) but not a return value of a
function or a 'new' object.
just to nag, an array is not a scalar value. However, you're correct on
this. Properties can only be defined in the class with constant values
(this does not mean they have to be constants! The values they get just
have to be fixed, and not determined during runtime.)
you should initialize the $address property in the contructor
of the User object like so:
class User {
public $name;
public $address;
function __construct($name = '')
{
$this->name = strval($name);
$this->address = new Address;
}
}
it's good practice to only set values to the objects
properties once it's contructed (or while it's being
constructed - as per my example).
