訪問SimpleXMLElement對象的一部分 - PHP

Question

我需要循環訪問下面的SimpleXMLElement Object中的數組items，但似乎無法使用$order->order->order->items訪問它。我可以使用相同的格式訪問交付和帳單地址，即。 $order->order->order->delivery_address，並希望以相同的方式進入items數組。不過，我得到一個空的SimpleXMLElement對象，當我print_r($order->order->order->items)

SimpleXMLElement Object

    [order] => SimpleXMLElement Object

使用丹閱讀建議，我試過的SimpleXMLElement ::兒童（），並做了工作

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

編輯：我剛纔看到你犯了一個錯誤的命名，家長需要調用<orders>和子項<order>

---

SimpleXMLElement 似乎爲空，實際上它通常是滿的，但在傾銷時不顯示（誰想到這種瘋狂的行爲）

你可以試試嗎？

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

或用SimpleXMLElement::children()

Answer 3

嘗試，你可以使用類似下面的一個循環，那麼所有你需要做的是$物品─> ID

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

     } 

Answer 4

您的項目實際上是在訂單數組的第二個偏移量。

我只是使用xPath來處理這些。

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