今天在网上闲逛，发现了一个很好用的PHP生成RSS的类：FeedCreator。尝试了一下，很不错，使用也非常简单，不多说，看实现代码：

<?php  
include("feedcreator.class.php");   
  
$rss = new UniversalFeedCreator();   
$rss->useCached(); // use cached version if age<1 hour  
$rss->title = "PHP news";   
$rss->description = "daily news from the PHP scripting world";   
  
//optional  
$rss->descriptionTruncSize = 500;  
$rss->descriptionHtmlSyndicated = true;  
  
$rss->link = "http://www.dailyphp.net/news";   
$rss->syndicationURL = "http://www.dailyphp.net/".$_SERVER["PHP_SELF"];   
  
$image = new FeedImage();   
$image->title = "dailyphp.net logo";   
$image->url = "http://www.dailyphp.net/images/logo.gif";   
$image->link = "http://www.dailyphp.net";   
$image->description = "Feed provided by dailyphp.net. Click to visit.";   
  
//optional  
$image->descriptionTruncSize = 500;  
$image->descriptionHtmlSyndicated = true;  
  
$rss->image = $image;   
  
// get your news items from somewhere, e.g. your database:   
mysql_select_db($dbHost, $dbUser, $dbPass);   
$res = mysql_query("SELECT * FROM news ORDER BY newsdate DESC");   
while ($data = mysql_fetch_object($res)) {   
    $item = new FeedItem();   
    $item->title = $data->title;   
    $item->link = $data->url;   
    $item->description = $data->short;   
      
    //optional  
    $item->descriptionTruncSize = 500;  
    $item->descriptionHtmlSyndicated = true;  
  
    $item->date = $data->newsdate;   
    $item->source = "http://www.dailyphp.net";   
    $item->author = "John Doe";   
?>  
       
    $rss->addItem($item);   
}
