Deep cloning an object : Clone vs Serialize

Question

I have this function duplicateCourseAction whose goal is to ... duplicate a Course object

public function duplicateCourseAction(Request $request) {
    if ($this         


        

Answer 1

You can control what exactly gets cloned by overriding the __clone() method in your Course entity. You can set id to null and clone referenced objects if you need a deep copy.

The serialization/unserialization feels like a hack, so I recommend against using it.
