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：

PHP RSS 生成类实例代码如下:复制代码 代码如下:<?php if (defined("_class_rss_php")) return; define("_class_rss_php教程",1); /**   *  使用说明：  *  $rss = new rss("redfox","http://jb51.net/","redfox"s blog");  *  $rss->additem("rss class","//www.rzxsoft.cn","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);    } } ?>
