  本文实例讲述了PHP生成RSS文件类文件。分享给大家供大家参考。具体如下:
 
  PHP RSS 生成类实例代码如下:
 
  <?php
  if (defined('_class_rss_php')) return;
  define('_class_rss_php粉丝网',1);
  /**
   
   *  使用说明:
   *  $rss = new rss('redfox','http://phpfensi.com/',"redfox's blog");
   *  $rss->additem('rss class',"https://www.phpfensi.com","xxx",date());
   *  $rss->additem(...);
   *  $rss->savetofile(...);
   */
   
  class rss {
     //public
     $rss_ver = "2.0";
     $channel_title = '';
     $channel_link = '';
     $channel_description = '';
     $language = 'zh_cn';
     $copyright = '';
     $webmaster = '';
     $pubdate = '';
     $lastbuilddate = '';
     $generator = 'redfox rss generator';
   
     $content = '';
     $items = array();
   
     function rss($title, $link, $description) {
         $this->channel_title = $title;
         $this->channel_link = $link;
         $this->channel_description = $description;
         $this->pubdate = date('y-m-d h:i:s',time());
         $this->lastbuilddate = date('y-m-d h:i:s',time());
     }
   
     function additem($title, $link, $description ,$pubdate) {
         $this->items[] = array('titile' => $title ,
                          'link' => $link,
                          'description' => $description,
                          'pubdate' => $pubdate);
     }
   
     function buildrss() {
         $s = "<!--l version="1.0" encoding="gb2312"--> ";
         // start channel
         $s .= " ";
         $s .= " "
         $s .= "<link />{$this->channel_link} ";
         $s .= "{$this->channel_description} ";
         $s .= "{$this->language} ";
         if (!emptyempty($this->copyright)) {
            $s .= "{$this->copyright} ";
         }
         if (!emptyempty($this->webmaster)) {
            $s .= "{$this->webmaster} ";
         }
         if (!emptyempty($this->pubdate)) {
            $s .= "{$this->pubdate} ";
         }
   
         if (!emptyempty($this->lastbuilddate)) {
            $s .= "{$this->lastbuilddate} ";
         }
   
         if (!emptyempty($this->generator)) {
            $s .= "{$this->generator} ";
         }
         
         // start items
         for ($i=0;$iitems),$i++) {
             $s .= " ";
             $s .= " ";
             $s .= "<link />{$this->items[$i]['link']} ";
             $s .= "<!--data[{$thi-->items[$i]['description']}]]> ";
             $s .= "{$this->items[$i]['pubdate']} ";           
             $s .= " ";
         }
        
        // close channel
        $s .= " ";
        $this->content = $s;
     }
   
     function show() {
         if (emptyempty($this->content)) $this->buildrss();
         header('content-type:text/xml');
         echo($this->content);
     }
   
     function savetofile($fname) {
         if (emptyempty($this->content)) $this->buildrss();
         $handle = fopen($fname, 'wb');
         if ($handle === false)  return false;
         fwrite($handle, $this->content);
         fclose($handle);
     }
  }
  ?>
  希望本文所述对大家的PHP程序设计有所帮助。
