php 生成RSS文件类实例代码

RSS可以是以下三种解释中任一种的缩写，但其实这三者都是指同一种联合供稿（Syndication）的技术：

这篇文章主要介绍了PHP生成RSS文件类,可实现PHP生成RSS文件的功能,对于网站建设与优化来说具有一定的实用价值,需要的朋友可以参考下

PHP RSS 生成类实例代码如下:

代码如下:

 ?php if (defined( _html' target='_blank'>class_rss_php )) return; define( _class_rss_php教程 ,1); 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); ? 

以上就是php 生成RSS文件类实例代码的详细内容，其它编程语言
