object orientation question

[purencool]

I have instantiated a object and the constructor has an other object added the issue arises when I  extent the first object how do I access the object in the variable. below is a stripped down example. I want accessfoo to access class a method foo that is stored in a var in class b is this possible.

class a {
private function foo(){
return "hello word";
}
}


$a = new a()


class b {
    private $obj;
    public function __construct ($obj){

        $this->obj= $obj;

    }

}

class c extends b{

private function accessfoo(){
    $this->obj ?????????????
}

$c = new class($a)

If you want foo() and $obj private then no*.

 

 

* Unless you use reflection, which is not the solution to badly-designed objects.

ok then how could  I use a similar class layout but change the methods? what syntax would I need?

I suggest reading the following examples:

http://php.net/manual/en/language.oop5.visibility.php

 

Here are the correct access levels for your class methods:

<?php
class a {
public function foo() {
	print "hello word";
}
}

class b {
    protected $obj;
    public function __construct($obj) {
        $this->obj = $obj;
    }
}

class c extends b {
public function accessfoo(){
    	$this->obj->foo();
}
}

$a = new a();
$c = new c($a);
$c->accessfoo();
?>

thank you very much. It would have taken me a month to work it out.
