Magento 1.9 – How to Get All Information About Order

How I tried this:

error_reporting( E_ALL );
require_once "lib/nusoap.php";
require_once "../app/Mage.php";
Mage::app('admin');
try {
    $order = Mage::getModel('sales/order')->loadByIncrementId('242647');
    print_r($order->debug());
} catch (Exception $e) {
    echo 'Caught exception: ',  $e->getMessage(), "\n";
}

but it does not seem to work.
No errors, nothing.

I change a bit my approach and now it looks like:

include('./app/Mage.php');
Mage::app();
$mage_php_url = '../app/Mage.php';

$OrderNumber = "242647";//My Order Number here
$order = Mage::getModel('sales/order')->load($OrderNumber, 'increment_id');
$orderId = $order->getData('order_id');
print($orderId);

$order->getAllVisibleItems();
$orderItems = $order->getItemsCollection()
    ->addAttributeToSelect('*')
    ->addAttributeToFilter('product_type', array('eq'=>'simple'))
    ->load();

foreach($orderItems as $sItem) {

if($sItem->getProductType() == "simple")
{
    echo "\n*********************************\nMage Order #: ".$OrderNumber."\n";
    //Simple Item Info from Order
    echo "Type: ".$sItem->getProductType()."\n";
    echo "Order Id: ".$sItem->getOrderId()."\n";
    echo "Product Id: ".$sItem->getProductId()."\n";
    echo "Item Id: ".$sItem->getId()."\n";
    echo "Item Name: ".$sItem->getName()."\n";
    echo "Item Sku: ".$sItem->getSku()."\n";
    echo "Item Price: ".$sItem->getPrice()."\n";

    $pItemId = $sItem->getParentItemId();
    echo "Parent Item Id: ".$pItemId."\n";

    echo "\n*****\n";

    //Get Parent Item Information
$item = Mage::getModel('sales/order_item')->load("$pItemId"); //use an item_id here
    //Testing, want to see whats inside the parent/configurable item?
    print_r($item->toArray());

    echo "Parent Type: ".$item->getProductType()."\n";
    echo "Parent Order Id: ".$item->getOrderId()."\n";
    echo "Product Id: ".$item->getProductId()."\n";
    echo "Item Id: ".$item->getId()."\n";
    echo "Parent Item Price: ".$item->getPrice()."\n";
    echo "Qty: ".$qty = intval($item->getQtyOrdered())."\n";

    //get Active Product Data
    $nProduct = Mage::getModel('catalog/product')->load($sItem->getProductId());
    $nSku = $nProduct->getSku();
echo "new Product UPC:".$nUpc = $nProduct->getUpc() . "\n";
    echo "new Product Price:".$nPrice = $nProduct->getPrice(). "\n";

    }
}

but still nothing 😉
