PHP - RSS 生成器 [英] PHP - RSS builder

问题描述

我有一个旧网站，每次创建新帖子时都会生成自己的 RSS.当我在使用 PHP 4 的服务器上时一切正常，但现在主机更改为 PHP 5，我总是有一个格式错误的 XML".我使用 xml_parser_create() 和 xml_parse(...) 和 fwrite(..) 来保存所有内容.

I have a old website that generate its own RSS everytime a new post is created. Everything worked when I was on a server with PHP 4 but now that the host change to PHP 5, I always have a "bad formed XML". I was using xml_parser_create() and xml_parse(...) and fwrite(..) to save everything.

这是保存时的示例(当然，我在保存之前阅读以附加旧的 RSS 行).

Here is the example when saving (I read before save to append old RSS line of course).

function SaveXml()
{
    if (!is_file($this->getFileName()))
    {
        //Création du fichier
        $file_handler = fopen($this->getFileName(),"w");

        fwrite($file_handler,"");

        fclose($file_handler);
    }//Fin du if

    //Header xml version="1.0" encoding="utf-8"
    $strFileData = '<?xml version="1.0" encoding="iso-8859-1" ?><rss version="2.0" xmlns:dc="http://purl.org/dc/elements/1.1/"><channel><title>'.$this->getProjectName().'</title><link>http://www.mywebsite.com</link><description>My description</description><lastBuildDate>' . date("r"). '</lastBuildDate>';

    //Data
    reset($this->arrData);
    foreach($this->arrData as $i => $value)
    {
        $strFileData .= '<item>';
            $strFileData .= '<title>'. $this->GetNews($i,0) . '</title>';
            $strFileData .= '<pubDate>'. $this->GetNews($i,1) . '</pubDate>';
            $strFileData .= '<dc:creator>'. $this->GetNews($i,2) . '</dc:creator>';
            $strFileData .= '<description><![CDATA['. $this->GetNews($i,3) . ']]> </description>';
            $strFileData .= '<link><![CDATA['. $this->GetNews($i,4) . ']]></link>';
            $strFileData .= '<guid>'. $this->GetNews($i,4) . '</guid>';
            //$strFileData .= '<category>'. $this->GetNews($i,5) . '</category>';
            $strFileData .= '<category>Mycategory</category>';
        $strFileData .= '</item>';

    }//Fin du for i


    $strFileData .= '</channel></rss>';



    if (file_exists($this->getFileName()))//Détruit le fichier
        unlink($this->getFileName());


    $file_handler = fopen($this->getFileName(),"w");



    fwrite($file_handler,$strFileData);

    fclose($file_handler);
}//Fin de SaveXml

我的问题是:如何在 PHP 中创建和填写 RSS?

My question is : how do you create and fill up your RSS in PHP?

推荐答案

在 swcombine.com，我们使用 Feedcreator.使用那个，你的问题就会消失.:)

At swcombine.com we use Feedcreator. Use that one and your problem will be gone. :)

这是安装后使用它的 PHP 代码:

Here is the PHP code to use it once installed:

function feed_simnews() {
    $objRSS = new UniversalFeedCreator();
    $objRSS->title = 'My News';
    $objRSS->link = 'http://link.to/news.php';
    $objRSS->description = 'daily news from me';
    $objRSS->xsl = 'http://link.to/feeds/feedxsl.xsl';
    $objRSS->language = 'en';
    $objRSS->copyright = 'Copyright: Mine!';
    $objRSS->webmaster = '[e-mail]';
    $objRSS->syndicationURL = 'http://link.to/news/simnews.php';
    $objRSS->ttl = 180;

    $objImage = new FeedImage();
    $objImage->title = 'my logo';
    $objImage->url = 'http://link.to/feeds/logo.jpg';
    $objImage->link = 'http://link.to';
    $objImage->description = 'Feed provided by link.to. Click to visit.';
    $objImage->width = 120;
    $objImage->height = 60;
    $objRSS->image = $objImage;

    //Function retrieving an array of your news from date start to last week
    $colNews = getYourNews(array('start_date' => 'Last week'));

    foreach($colNews as $p) {
        $objItem = new FeedItem();
        $objItem->title = $p->title;
        $objItem->description = $p->body;
        $objItem->link = $p->link;
        $objItem->date = $p->date;
        $objItem->author = $p->author;
        $objItem->guid = $p->guid;

        $objRSS->addItem($objItem);
    }

    $objRSS->saveFeed('RSS2.0', 'http://link.to/feeds/news.xml', false);
};

相当亲吻.:)
