If an object is typecasted into an array and "extracted",only the public properties will be accessible.Methods are of course omitted.
<?php
class Test{
    public $name = '';

    protected $age = 10;

    public $status = 'disabled';

    private $isTrue = false;

    public function __construct()
    {
        $this->name = 'Amolo';
        $this->status = 'active';
    }

    public function getName()
    {
        return $this->name;
    }

    public function getAge()
    {
        return $this->age;
    }

    public function getStatus()
    {
        return $this->status;
    }

}

$obj = (array) new Test();
var_dump($obj);
/* array(4) { ["name"]=> string(5) "Amolo" ["*age"]=> int(10) ["status"]=> string(6) "active" ["TestisTrue"]=> bool(false) } */

echo  $name; //Amolo

echo $age;//Notice: Undefined variable: age
echo $isTrue;//Notice: Undefined variable: isTrue
