How to get variable from one class in another class?

I have 2 classes: User and Answer

I define in the class User that the name is "Peter"

how can I get the name defined in the User instance inside the Answer instance?

$user= new User(); 
$user->name = "Peter";      


$answer = new Answer(); 
echo $answer->getListAnswer(); //how can I get the name of the User (Peter) in the function getListAnswer() in the Class Answer?

Inject the User instance into the Answer instance. Like this, for example:

class Answer
   private $user;

   public function __construct(User $user) {
      $this->user = $user;
   }

   public function getListAnswer() {
      $userName = $this->user->name;

      // rest of your method.
      // Use $userName where you need it.
   }
}

First you create your User object as usual:

$user       = new User(); 
$user->name = "Peter";

In the constructor for Answer we declared that it needs (depends on) a User object. So you pass the user object you just created to instantiate a new Answer:

$answer = new Answer($user); 
echo $answer->getListAnswer();

Well I'm not much sure of it, but if you try and define your variable scope with "global " in the Answer class,it might make some difference
