访问SimpleXMLElement对象的一部分 - PHP

Question

I need to loop through the items as an array within the SimpleXMLElement Object below but cannot seem to access it using $order->order->order->items . I can access the delivery and billing addresses using the same format, ie. $order->order->order->delivery_address and expected to get to the items array in the same way. However, I get an empty SimpleXMLElement Object when I print_r($order->order->order->items)

Answer 1

EDIT : I just saw you made a mistake with the naming, the parent needs to be called <orders> and the sub items <order>

---

The SimpleXMLElement seems to be empty, in fact it's usually filled but not displayed when dumping (whoever thought of this crazy behaviour)

Can you try this?

foreach($order->orders->order as $order) { // should be orders then
  echo $item->getName();
}

Or try it with SimpleXMLElement::children()

Answer 2

your items are actually on the second offset of the order array.

I'd just use the xPath to process these.

foreach($xmlObject->xpath('/order/order[2]/items') as $item)
{
   // Do something with my $item
}

Answer 3

You can use a loop like the one below, then all you need to do is $items->id

   foreach($order->children()->children()->items as $items)
      {

      }

Answer 4

Using Dan Lees suggestion I tried SimpleXMLElement::children() and did the below which works

foreach ($order->children() as $order) {
        foreach ($order->children() as $order_details) {
            foreach ($order_details->children() as $order_items) {
                echo $order_items->id;
            }
        }
    }
