<?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;?>
