前面的mysql.php 是封装的mysql数据库功能,单例模式,所以取对象是静态方法 mysql::getObject();

代码很简单,如下所示:

include 'mysql.php';

$mysql= mysql::getObject();

$mysql->query("SELECT * FROM post");

$xml = new XMLWriter();

$xml->openUri('hello.xml'); //  or 'php://output'

$xml->setIndentString('   ');

$xml->setIndent(true);

// start

$xml->startDocument('1.0', 'UTF-8');

// <rss version="2.0">

$xml->startElement('rss');

   $xml->writeAttribute('version','2.0');



// <channel>

$xml->startElement('channel');

     // title

     $xml->startElement('title');

          $xml->text('title');

     $xml->endElement();

     // link

     $xml->startElement('link');

          $xml->text('http://foodstory.me/post/');

     $xml->endElement();

     // description

     $xml->startElement('description');

          $xml->text('');

     $xml->endElement();

     // language

     $xml->startElement('language');

          $xml->text('zh-cn');

     $xml->endElement();

     // category

     $xml->startElement('category');

          $xml->text('IT');

     $xml->endElement();

     // copyright

     $xml->startElement('copyright');

          $xml->text('copyright 2011 foodstory.me');

     $xml->endElement();

     // for item

     while( $row = $mysql->fetch() )

     {

      $xml->startElement('item');

         // title

        $xml->startElement('title');

             $xml->text( $row['title']);

        $xml->endElement();

        // link

        $xml->startElement('link');

             $xml->text( 'http://foodstory.me/post/'.$row['id'].'.html');

        $xml->endElement();

        // description

        $xml->startElement('description');

             $xml->text( $row['text'] );

        $xml->endElement();

        // pubDate

        $xml->startElement('pubDate');

             $xml->text( date('D, d M Y H:i:s T', $row['time']) );

        $xml->endElement();



        // category tag author need to write .over

      $xml->endElement(); // item

     }

$xml->endElement(); // channel

$xml->endElement();  // rss

//开源代码Vevb.com

$xml->endDocument();

// $xml->flush();
