我是php的新手。

我正在创建一个php文件，可以使用myPHPAdmin中的数据生成xml文件。感谢：D。希望可以有人帮帮我。

首先尝试，代码已经在php中显示，当我打开以检查创建的XML时。显示为“$node”，当我尝试删除字符串引号（''）时，它反映了fwrite中的确切字符串。fwrite($dp,$node);。我收到了错误。

当我尝试将代码返回到fwrite（$ dp，'$ node'）;.没有显示。 XML页面是空白的。

使用PHP创建XML文件时，需要使用XML标头。

<?xml version="1.0" encoding="utf-8"?>

但是在最后使用saveXML()时不需要这样做。

这是一个从php手册中挑选出来的例子。

<?php

$doc = new DOMDocument('1.0');
// we want a nice output
$doc->formatOutput = true;

$root = $doc->createElement('book');
$root = $doc->appendChild($root);

$title = $doc->createElement('title');
$title = $root->appendChild($title);

$text = $doc->createTextNode('This is the title');
$text = $title->appendChild($text);

echo "Saving all the document:\n";
echo $doc->saveXML() . "\n";

echo "Saving only the title part:\n";
echo $doc->saveXML($title);
?>
