Get Class Name from Object inside Object - php

Question

I have 3 classes..
class 1 :
<?php
include "two.php";
include "three.php";
class One{
public function __construct(){
$two = new Two($this);
$three = new Three($two);
}
}
$api = new One;
?>
class 2 :
<?php
class Two extends AOP {
public function __construct($obj){
//blablabla
}
}
?>
class 3 :
<?php
class Three extends AOP {
public function __construct($obj){
echo get_class($obj);
}
}
?>
But I want the result must output "One".
How to get class name from object inside object?

Answer 1

In your design you have to implement a getter in class two:
class 2 :
class Two
{
private $myObj;
public function __construct($obj)
{
$this->myObj = $obj;
}
public function getMyObj()
{
return $this->myObj;
}
}
then in class 3, you can retrieve class 1:
class Three
{
public function __construct($obj)
{
echo get_class($obj->getMyObj());
}
}

Answer 2

Use the keyword extends to inherit another class. Since PHP does not support multiple inheritances directly. You can get the class that you extend from with parent::$property; or parent::method();. So, you probably want your code to look more like.
// three.php
class Three extends AOP{
public function __construct($obj){
echo get_class($obj);
}
}
// two.php
class Two extends Three{
public function __construct($obj){
parent::__construct($obj); // Constructors do not return a value echo works
}
protected function whatever($string){
return $string;
}
}
// one.php
include 'three.php'; // must be included first for Two to extend from
include 'two.php'
class One extends Two{
public function __construct(){
// change this part
parent::__construct($this); // uses the parent Constructor
echo $this->whatever('. Is this what you mean?'); // call method without same name in this class - from parent
}
}
$api = new One;
I would not use your structure at all, but this should give you an idea of inheritance.
