PHP解析RSS的方法

本文实例讲述了PHP解析RSS的方法。分享给大家供大家参考。具体如下：

1. php代码如下：    

<?php

require "XML/RSS.php";

$rss = new XML_RSS("http://php.net/news.rss");

$rss->parse();

foreach($rss->getItems() as $item) {

  print_r($item);

}

?>

2. RSS.php代码如下：

<?php

$database =  "nameofthedatabase";

$dbconnect = mysql_pconnect(localhost, dbuser, dbpassword);

mysql_select_db($database, $dbconnect);

$query = "select link, headline, description from `headlines` limit 15";

$result = mysql_query($query, $dbconnect);

while ($line = mysql_fetch_assoc($result))

{

    $return[] = $line;

}

$now = date("D, d M Y H:i:s T");

$output = "<?xml version=\"1.0\"?>

    <rss version=\"2.0\">

 <channel>

     <title>Our Demo RSS</title>

     <link>http://www.tracypeterson.com/RSS/RSS.php</link>

     <description>A Test RSS</description>

     <language>en-us</language>

     <webMaster>[e-mail]</webMaster>

    ";

foreach ($return as $line)

{

    $output .= "<item><title>".htmlentities($line['headline'])."</title>

                    <link>".htmlentities($line['link'])."</link>

<description>".htmlentities(strip_tags($line['description']))."</description>

                </item>";

}

$output .= "</channel></rss>";

header("Content-Type: application/rss+xml");

echo $output;

?>
