[PHP-WEBMASTER] Public, Protected, and Private -- Not working

[Michael Cinicola]

The last line in the example:


class MyClass
{
    public $public = 'Public';
    protected $protected = 'Protected';
    private $private = 'Private';

    function printHello()
    {
        echo $this->public;
        echo $this->protected;
        echo $this->private;
    }
}

$obj = new MyClass();
echo $obj->public; // Works
echo $obj->protected; // Fatal Error
echo $obj->private; // Fatal Error
$obj->printHello(); // Shows Public, Protected and Private


does not show public, protected, and private:

Tried on Chrome and Safari on macOS Sierra — no result on either.
