This is correct. In PHP 5, objects are passed and assigned by
reference and you need to use the clone operator to duplicate them.

$original = new van_gogh_painting;
$knock_off = clone $original;

You can control the cloning process by defining a __clone() method
inside the class; otherwise, you just get regular copy of all the
object properties.
