php写xml文件出错, 请求帮助! 在线等待

Question

php写xml文件老是出错,一时找不到原因, 请求大伙帮助!
以下是我的程序代码:
<?php>
$txtmail = $_POST["txtemail"];
$txtname = $_POST["txtname"];
$txtmsg = $_POST["txtmessage"];$doc = newDOMDocument("1.0");
$doc->load("xmlorders.xml");
$root=$doc->getElementsByTagName("orders")->item(0);
$order = $doc->createElement("order");
$name = $doc->createElement("name");
$email = $doc->createElement("email");
$message = $doc->createElement("message");
$date = $doc->createElement("createdate");$name->appendChild($doc->createTextNode($txtname));
$email->appendChild($doc->createTextNode($txtmail));
$message->appendChild($doc->createTextNode($txtmsg));
$date->appendChild($doc->createTextNode(date("Y-m-j")+" "+date("G:i:s")));$order->appendChild($name);
$order->appendChild($email);
$order->appendChild($message);
$order->appendChild($date);
$root->appendChild($order);
//echo$doc->saveXML();
$doc->save("xmlorders.xml");
?>是不是xml文件必须得到物理路径?
谢谢! 

Answer 1

function addOrder($doc, $value)
{
    $item = $doc->createElement('order');
    $cdata = $doc->createCDATASection($value);
    $item->appendChild($cdata);
    $doc->documentElement->appendChild($item);
}
$txtmail = $_POST["txtemail"];
$txtname = $_POST["txtname"];
$txtmsg = $_POST["txtmessage"];
$doc = new DOMDocument();
$doc->loadXML('<orders></orders>');addOrder($doc, $txtmail);
addOrder($doc, $txtname);
addOrder($doc, $txtmsg);$doc->save('D:/test.xml');

Answer 2

不行的, 我的代码是要加载已经在的xml文件, 然后再新增节点xml与php文件放在同一个目录下，能访问到吗？

Answer 3

可以的另外楼主的代码有错 多了个> 还有new那里没有空格 测试通过 
<?php
$txtmail = "txtemail";
$txtname = "txtname";
$txtmsg = "txtmessage";$doc = new DOMDocument("1.0");
$doc->load("xmlorders.xml");
$root=$doc->getElementsByTagName("orders")->item(0);
$order = $doc->createElement("order");
$name = $doc->createElement("name");
$email = $doc->createElement("email");
$message = $doc->createElement("message");
$date = $doc->createElement("createdate");$name->appendChild($doc->createTextNode($txtname));
$email->appendChild($doc->createTextNode($txtmail));
$message->appendChild($doc->createTextNode($txtmsg));
$date->appendChild($doc->createTextNode(date("Y-m-j")+" "+date("G:i:s")));$order->appendChild($name);
$order->appendChild($email);
$order->appendChild($message);
$order->appendChild($date);
$root->appendChild($order);
//echo$doc->saveXML();
$doc->save("xmlorders.xml");
?>

Answer 4

$txtmail = $_POST["txtemail"];
$txtname = $_POST["txtname"];
$txtmsg = $_POST["txtmessage"];if(file_exists('test.xml') === false)
{
    $fp = fopen('test.xml', 'w+');
    fwrite($fp, '<?xml version="1.0" encoding="UTF-8" ?><orders></orders>');
    fclose($fp);
}$doc = new DOMDocument('1.0', 'UTF-8');
$doc->load('test.xml');$order = $doc->createElement('order');$name = $doc->createElement("name");
$email = $doc->createElement("email");
$message = $doc->createElement("message");
$date = $doc->createElement("createdate");$name->appendChild($doc->createCDATASection($txtname));
$email->appendChild($doc->createCDATASection($txtmail));
$message->appendChild($doc->createCDATASection($txtmsg));
$date->appendChild($doc->createCDATASection(date("Y-m-j")+" "+date("G:i:s")));$order->appendChild($name);
$order->appendChild($email);
$order->appendChild($message);
$order->appendChild($date);$doc->documentElement->appendChild($order);$doc->save('test.xml');
这个已经测试过...

Answer 5

6楼结果是
 <?xml version="1.0" encoding="UTF-8" ?> 
- <orders>
- <order>
- <name>
- <![CDATA[ my name
  ]]> 
  </name>
- <email>
- <![CDATA[ my mail
  ]]> 
  </email>
- <message>
- <![CDATA[ my message
  ]]> 
  </message>
- <createdate>
- <![CDATA[ 2024
  ]]> 
  </createdate>
  </order>
  </orders>

Answer 6

不知为什么写xml那么麻烦，用echo 直接把字符串写到指定路径，加上文件命名就可以了， 用这个 DOMDocumentod 不会有点问题复杂化吗？

Answer 7

上次给别人调数据用生成的xml用echo就不行，还是用dom组件
