*
* ### Example: tracking Ecommerce interactions
*
* Here is an example showing how to track Ecommerce interactions on your website, using the PHP Tracking API.
* Usually, Ecommerce tracking is done using standard Javascript code,
* but it is very common to record Ecommerce interactions after the fact
* (for example, when payment is done with Paypal and user doesn't come back on the website after purchase).
* For more information about Ecommerce tracking in Piwik, check out the documentation: Tracking Ecommerce in Piwik.
*
* $t = new PiwikTracker( $idSite = 1, 'http://example.org/piwik/');
*
* // Force IP to the actual visitor IP
* $t->setTokenAuth( $token_auth );
* $t->setIp( "134.10.22.1" );
*
* // Example 1: on a Product page, track an "Ecommerce Product view"
* $t->setUrl( $url = 'http://www.mystore.com/Endurance-Shackletons-Legendary-Antarctic-Expedition' );
* $t->setEcommerceView($sku = 'SKU0011', $name = 'Endurance - Shackleton', $category = 'Books');
* $t->doTrackPageView( 'Endurance Shackletons Legendary Antarctic Expedition - Mystore.com');
*
* // Example 2: Tracking Ecommerce Cart containing 2 products
* $t->addEcommerceItem($sku = 'SKU0011', $name = 'Endurance - Shackleton' , $category = 'Books', $price = 17, $quantity = 1);
* // Note that when setting a product category, you can specify an array of up to 5 categories to track for this product
* $t->addEcommerceItem($sku = 'SKU0321', $name = 'Amélie' , $categories = array('DVD Foreign','Best sellers','Our pick'), $price = 25, $quantity = 1);
* $t->doTrackEcommerceCartUpdate($grandTotal = 42);
*
* // Example 3: Tracking Ecommerce Order
* $t->addEcommerceItem($sku = 'SKU0011', $name = 'Endurance - Shackleton' , $category = 'Books', $price = 17, $quantity = 1);
* $t->addEcommerceItem($sku = 'SKU0321', $name = 'Amélie' , $categories = array('DVD Foreign','Best sellers','Our pick'), $price = 25, $quantity = 1);
* $t->doTrackEcommerceOrder($orderId = 'B000111387', $grandTotal = 55.5, $subTotal = 42, $tax = 8, $shipping = 5.5, $discount = 10);
*
* ### Note: authenticating with the token_auth
*
* To set the visitor IP, or the date and time of the visit, or to force to record the visit (or page, or goal conversion) to a specific Visitor ID,
* you must call setTokenAuth( $token_auth ). The token_auth must be either the Super User token_auth,
* or the token_auth of any user with 'admin' permission for the website you are recording data against.
