php - change arrays of value in another instance of class

Question

I am playing around with some php, and I found myself wondering something.

    <?php

class license
{

    public $v=array('product'=>"babab");
    function blah($b)
    {
        if (//code)
        {
            //code
        }
    }

Is there a way to change the values of the array in another instance of the class?

For example...

    $c = new license;
    //change $v values??
    $c->blah('woof.php');

How can I change the value of product in the $v array there?

I hope I was clear.

it should as simple as $c->$v[product]="new key"

Since you declared it as public, anyone can write to it that has an instance of the class.

$c->v = array('key', 'value');

You could change it to any data type you want.

$c->v = new MyObject();
$c->v = NULL;
$c->v = FALSE;
$c->v = 1;

But if you are saying that you want to create an additional license object and be able to change the value of your property, you wouldn't be able to with your existing architecture. The singleton design pattern solves this.

class License {
  private static $instance;
  private $v;
  private function __construct() {}
  private function __clone() {}

  public static function getInstance() {
    if(!isset(self::$instance)) {
      self::$instance = new static();
    }
    return self::$instance;
  }
  public function setV($data) {
    $this->v = $data;
  }
  public function getV() {
    return $this->v;
  }
}

$license = License::getInstance();
$license->setV(array("key" => "value"));
var_dump($license->getV());

$license2 = License::getInstance();
var_dump($license == $license2);
// true

You can change public class property by class object like this:

Live Demo : https://eval.in/91444

class license
    {

        public $v=array('product'=>"babab");
        function blah($b)
        {
            if (1)
            {
               echo "";
            }
        }

     }

     $c = new license;
     $c->v['product'] = "new values";
     echo $c->v['product'];
