第二种方法：

复制代码 代码如下:

<?php

header("Content-type: text/xml");

echo "<?xml version=/"1.0/" encoding=/"UTF-8/"?>";

echo "<users><user><name>小小菜鸟</name><age>24</age><sex>男</sex></user><user><name>艳艳</name><age>23</age><sex>女</sex></user></users>";

?>

第三种方法：

复制代码 代码如下:

<?php

/*

用PHP的DOM控件来创建XML输出

设置输出内容的类型为xml

*/

header('Content-Type: text/xml;');

//创建新的xml文件

$dom = new DOMDocument('1.0', 'utf-8');

//建立<response>元素

$response = $dom->createElement('response');

$dom->appendChild($response);

//建立<books>元素并将其作为<response>的子元素

$books = $dom->createElement('books');

$response->appendChild($books);

//为book创建标题

$title = $dom->createElement('title');

$titleText = $dom->createTextNode('PHP与AJAX');

$title->appendChild($titleText);

//为book创建isbn元素

$isbn = $dom->createElement('isbn');

$isbnText = $dom->createTextNode('1-21258986');

$isbn->appendChild($isbnText);

//创建book元素

$book = $dom->createElement('book');

$book->appendChild($title);

$book->appendChild($isbn);

//将<book>作为<books>子元素

$books->appendChild($book);

//在一字符串变量中建立XML结构

$xmlString = $dom->saveXML();

//输出XML字符串

echo $xmlString;
