Question

Which one of the following is the right way to clone an object?

(a) _clone(targetObject);

(b) destinationObject = clone targetObject;

(c) destinationObject = _clone(targetObject);

(d) destinationObject = clone(targetObject);

This question was addressed to me in exam.

I'm obligated to ask this question of Advanced Object-Oriented PHP topic in chapter Object-Oriented PHP of PHP

Answer 1

Correct choice is (b) destinationObject = clone targetObject;

Easy explanation: You can clone an object by prefacing it with the clone keyword. A copy of an object is created by using the clone keyword. $copy_of_object = clone $object;
