PHP生成RSS文件类实例
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:
PHPRSS生成类实例代码如下:
<?php if(defined('_class_rss_php'))return; define('_class_rss_php教程',1); /** * 使用说明: * $rss=newrss('redfox','http://jb51.net/',"redfox'sblog"); * $rss->additem('rssclass',"https://www.nhooo.com","xxx",date()); * $rss->additem(...); * $rss->savetofile(...); */ classrss{ //public $rss_ver="2.0"; $channel_title=''; $channel_link=''; $channel_description=''; $language='zh_cn'; $copyright=''; $webmaster=''; $pubdate=''; $lastbuilddate=''; $generator='redfoxrssgenerator'; $content=''; $items=array(); functionrss($title,$link,$description){ $this->channel_title=$title; $this->channel_link=$link; $this->channel_description=$description; $this->pubdate=date('y-m-dh:i:s',time()); $this->lastbuilddate=date('y-m-dh:i:s',time()); } functionadditem($title,$link,$description,$pubdate){ $this->items[]=array('titile'=>$title, 'link'=>$link, 'description'=>$description, 'pubdate'=>$pubdate); } functionbuildrss(){ $s="<!--lversion="1.0"encoding="gb2312"-->"; //startchannel $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}"; } //startitems 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.=""; } //closechannel $s.=""; $this->content=$s; } functionshow(){ if(emptyempty($this->content))$this->buildrss(); header('content-type:text/xml'); echo($this->content); } functionsavetofile($fname){ if(emptyempty($this->content))$this->buildrss(); $handle=fopen($fname,'wb'); if($handle===false) returnfalse; fwrite($handle,$this->content); fclose($handle); } } ?>
