<?php

require('rssbuilder.class.php');
header('Content-Type: application/xml; charset=UTF-8');
header('Cache-Control: no-cache, must-revalidate');
header('Expires: Fri, 14 Mar 1980 20:53:00 GMT');

header('Pragma: no-cache');
$rss = new RSSBuilder('utf-8', 'http://www.codepearl.com', '代码珠玑', '一个强大的代码分析平台', 'http://www.codepearl.com/logo.png');
$rss->addDCdata('', 'http://www.codepearl.com', date('r'));

	   $data = array(
			array(
				'id'=>1,
				'name'=>'php',
				'desc'=>'php分享频道',
				'start_time'=>'2013-11-17'
			),
			array(
				'id'=>17,

			)
	   );
	   
	   foreach($data as $key=>$value)
	   {
	    $rss->addItem('http://www.codepearl.com/files/list_'.$value['id'].'.html', $value['name'], 'http://www.codepearl.com/files/list_'.$value['id'].'.html'. 'from=rss', $value['desc'], $value['name'], $value['start_time']);
