Answer 1

_data is a protected variable so you won't be able to access it from outside the object. You'll need to use (or create) a getData() method that accesses$this->_data. Just call that method and you'll have access to the options array.

Example method that accesses _data and returns my_options all in one:

public function getMyOptions() {
  return $this->_data['my_options'];
}

Which can be invoked with something like:

$product instanceof app\models\Product;
$myOptions = $product->getMyOptions();

Also, it looks like you're using a model (possibly orm) class. I would imagine it has built-in methods to access the data array. Common methods to access my_options would be:

$options = $product->my_options; // via magic methods
$options = $product->get('my_options');
$options = $product->getField('my_options');
