In PHP 5, objects are passed (into and out of functions, etc) and
copied by reference. Everything else (scalars, strings, booleans,
etc.) behave the same and are passed by value.

To make a by-value copy of an object, use the clone operator:

$copy = clone $original;

To control the cloning behavior of a class, define a __clone() method.

More details available in "Upgrading to PHP 5." :)
