Understanding Classes in PHP

Question

I am officially mentally retarded. [Let me explain]

I have never given lessons and their relationship until today. I'm trying to understand something that seems pretty obvious, but since I'm stupid, I don't see it.

Let's say I have a base class that will be extended from different files. How classes of children can invoke functions from other siblings (that is, if they are considered children at all). Code example: (don't kill me)

class cOne { 
    public function functionOne(){
       echo "something";
    }
}

Then in another file I say:

class cOneChildOne extends cOne { 
    public function functionOne(){
       echo "something from child one";
    }
}

And in another file I say:

class cOneChildTwo extends cOne { 
    public function functionOne(){
       echo "something from child two";
    }
}

How can I create a new object, and when I can access the functions from both the children and the parent class in a similar style $newObject->Children->function();, I seriously consider the option, today I lost my brain and I can’t think straight.

Answer 1

class C1{  
  static public $childs=array();
  function __construct(){
    self::$childs[]=$this;    
  }
}
class C1C1 extends C1{
  function hi(){
    echo 'hi from C1C1 <br />';
  }  
}
class C1C2 extends C1{
  function hi(){
    echo 'hi from C1C2 <br />';
  }    
}

$c1 = new C1C2();
$c2 = new C1C2();
$c3 = new C1C1();
$c4 = new C1C1();
$c5 = new C1C1();
$c6 = new C1C1();
foreach(C1::$childs as $c){
  $c->hi();
}

Answer 9

Why don't you have static Array $childrena class cOne, and the methods __construct()for the classes that extend it are simply called cOne::addChild($this)? Each of them can implement a function getChildrenthat sends a request to a superclass - should it not work?
