php写xml, 赋值由数组怎么弄

[jellday]

<?php

 //Creates XML string and XML document using the DOM
 $dom = new DomDocument('1.0');
 
 //add root - <books>
 $books = $dom->appendChild($dom->createElement('books'));
 
 //add <book> element to <books>
 $book = $books->appendChild($dom->createElement('book'));
 
 //add <title> element to <book>
 $title = $book->appendChild($dom->createElement('title'));
 
 //add <title> text node element to <title>
 $title->appendChild($dom->createTextNode('Great American
 Novel'));
 
 //generate xml
 $dom->formatOutput = true; // set the formatOutput attribute of
 domDocument to true
 // save XML as string or file
 $test1 = $dom->saveXML(); // put string in test1
 $dom -> save('test1.xml'); // save as file
 ?>

输出文件

  <?xml version="1.0"?>
 <books>
 <book>
 <title>Great American Novel</title>
 </book>
 </books>
 

如果title的值由$lw[0]['title']得到,应该怎么弄啊?

//这样对吗？

<?php

$lw= array(array('title'=>"Love Story"));

 //Creates XML string and XML document using the DOM
 $dom = new DomDocument('1.0');
 
 //add root - <books>
 $books = $dom->appendChild($dom->createElement('books'));
 
 //add <book> element to <books>
 $book = $books->appendChild($dom->createElement('book'));
 
 //add <title> element to <book>
 $title = $book->appendChild($dom->createElement('title'));
 
 //add <title> text node element to <title>

 $title->appendChild($dom->createTextNode($lw[0]['title']));
 
 //generate xml
 $dom->formatOutput = true; // set the formatOutput attribute of domDocument to true
 // save XML as string or file
 $test1 = $dom->saveXML(); // put string in test1
 $dom -> save('test1.xml'); // save as file
 ?>

非常感谢!

有个问题, 如果数组的编码为gb2312, 我得到错误

Warning: DOMDocument::saveXML() [domdocument.savexml]: string is not in UTF-8 in C:\PHPnow\htdocs\test.php on line 48

Warning: DOMDocument::saveXML() [domdocument.savexml]: string is not in UTF-8 in C:\PHPnow\htdocs\test.php on line 48

Warning: DOMDocument::save() [domdocument.save]: string is not in UTF-8 in C:\PHPnow\htdocs\test.php on line 49

是不是要指定xml编码为gb2312呢? 如何指定?
