将对象分配给新类

Question

I have a class:

$b = new Model();

And I have a different class:

$c = new Model();

I want $b to be $c .

How do I accomplish this?

Answer 1

$b = $c $b now references $c both refer the the same instance*

$b = clone $c; $b is a copy of $c each refers to a different instance of the Model*
