PHP SimpleXML輕微更改後失敗

我有一個腳本，它接受表單數據並將其提交給一個XML文件，但是在添加了一些額外的節點後，該腳本返回一個空白頁並且無法寫入XML，甚至沒有返回在最後回聲'添加另一個'。這件事我完全不知所措。在諮詢了我們的服務器供應商之後，一切都看起來很好。有什麼建議麼？PHP SimpleXML輕微更改後失敗

有什麼錯在你的Apache的詳細說明'error.log'文件。 – mudasobwa 2014-11-24 18:27:21

$element->getElementsByTagName()返回れ對象，但$xml->createElement()詢問兩個字符串。

所以，當你試圖創建一個$name或$vendor作爲一個值的元素，你要求PHP將一個DomNode轉換爲一個字符串，但它不能這樣做。你可以在你的日誌文件中找到一些像這樣的錯誤： Catchable fatal error: Object of class DOMElement could not be converted to string on line XX

爲了得到一個字符串，你需要使用nodeValue屬性：

$name = $element->getElementsByTagName('name')->item(0)->nodeValue; 
$description = $element->getElementsByTagName('description')->item(0)->nodeValue; 
$price = $element->getElementsByTagName('price')->item(0)->nodeValue; 
$our_price = $element->getElementsByTagName('ourprice')->item(0)->nodeValue; 
$quantity = $element->getElementsByTagName('quantity')->item(0)->nodeValue; 
$size = $element->getElementsByTagName('size')->item(0)->nodeValue; 
$color = $element->getElementsByTagName('color')->item(0)->nodeValue; 
$vendor = $element->getElementsByTagName('vendor')->item(0)->nodeValue; 
$category = $element->getElementsByTagName('category')->item(0)->nodeValue; 
$subcategory = $element->getElementsByTagName('subcategory')->item(0)->nodeValue;
