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('_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); } } ?>
