$product->getOptions() behavior inconsistent

Question

If I run code to load a product and its options in a product view template file app/design/frontend/mymodule/default/template/catalog/product/view.phtml

$product = Mage::getModel("catalog/product")->load($productId);
$options = $product->getOptions();

it works as expected. However, if I run the same code for the same product in a controller of my custom module $options is an empty array.

Is there some initialization code I'm missing?

Try this :

 <?php

    $productID = 45

    $product = Mage::getModel('catalog/product')->load($productID);
    $options = Mage::getModel('catalog/product_option')->getProductOptionCollection($product);

    foreach ($options as $option) {
        Mage::log('Name: ' . $option->getDefaultTitle());
        Mage::log('    Type: ' . $option->getType());
        Mage::log('    Class: ' . get_class($option));
        Mage::log('    Price/Type: ' . ($option->getPrice() ? $option->getPrice() : '0.00') . ' / ' . $option->getType());

        if ($option->getType() === 'drop_down') {
            $values = Mage::getSingleton('catalog/product_option_value')->getValuesCollection($option);
            Mage::log('    Values: (name/price/type)');

            foreach ($values as $value) {
                Mage::log('        ' . $value->getTitle() . ' / ' . $value->getPrice() . ' / ' . $value->getPriceType());;
            }
        }
    }
    ?>

for configurable products, you can get product option like below:

$product = Mage::getModel("catalog/product")->load($productId);
$productAttributeOptions =$product->getTypeInstance(true)->getConfigurableAttributesAsArray($product);
$attributeOptions = array();
foreach ($productAttributeOptions as $productAttribute) {
    foreach ($productAttribute['values'] as $attribute) {
        $attributeOptions[$productAttribute['label']] [$attribute['value_index']] = $attribute['store_label'];
    }
}

I hope this will helpful to you.
