PHP5 automatically calls a function called __clone() during the
cloning process. This can be used to make deep clones of objects by
cloning all the object properties.
Example:
class Test {
function __clone() {
$this->property1 = clone($this->property1);
$this->property2 = clone($this->property2);
}
That might help.
