將PHP輸出轉換爲XML - 創建RSS源

Question

當前代碼使我輸出到「li」，並且我想將輸出調整爲有效的XML，以便我可以從該列表創建RSS源。有什麼建議？

這裏是我到目前爲止的代碼：

<?php 
session_start(); 
mb_internal_encoding('UTF-8'); 
require_once('../config.php'); 
require_once('../dbconnect.php'); 
echo ' <div class="tagsz clearfix"> '; 
echo "<ul id='mytags_ara'>"; 
echo "<h2 class='title'>English Trends</h2>"; 
echo ' <div class="tagsz clearfix"> '; 
echo "<ul id='mytags_en'>"; 
$query = "SELECT hashtag, sum(count) as total FROM `trending_topics` WHERE lang=0 and hashtag != '' and date >= date_sub(left(now(), 10), interval 1 day) group by hashtag  order by total desc"; 
    $res = mysql_query($query); 
$index = 0; 
$hashtags = null; 
while($row = mysql_fetch_assoc($res)) { 
$hashtag = $row['hashtag']; 
if(strtolower($hashtag) != 'newnew' && strtolower($hashtag) != 'new' && strtolower ($hashtag) != 'more') { 
echo "<li><a class='size".$index."'".$hashtag."'>#".$hashtag."</a></li>"; 
$index++; 
} 
if($index==6) break;} 
echo "</ul>"; 
echo "</div>"; 
?>

這可能會或可能不會幫助你，但是這是我用生成的Atom feed代碼：

<?php 
    define('DS', DIRECTORY_SEPARATOR); 
    define('ROOT', dirname(dirname(__file__))); 
    define('HOST', 'http://' . $_SERVER['HTTP_HOST'] . dirname($_SERVER['PHP_SELF'])); 

    function publishAtom() { 
      /* 
      My data entities had these fields: 
      - title 
      - category 
      - permalink (a URL-safe version of the title) 
      - timestamp 
      - lastupdated 
      - abstract 

      You'll need to adjust the code below to match your entities. 
      */ 

      # get the data 
      $rows = //<<insert your data-gathering-code here>> -> needs to be an array of your entities; 


      $feed_title = "Atom Feed"; 
      $feed_subtitle = "Get all our newest entries when you subscribe to the feed."; 
      $site_domain = "http://yourdomain.com"; 
      $author_name = "Your Name"; 
      $author_email = "yourname@yourdomain.com"; 

      $feed = '<?xml version="1.0" encoding="utf-8"?> 
      <feed xmlns="http://www.w3.org/2005/Atom"> 
       <title>' . $feed_title . '</title> 
       <subtitle>' . $feed_subtitle . '</subtitle> 
       <link href="' . $site_domain . '/atom.xml" rel="self" /> 
       <link href="' . $site_domain . '" /> 
       <updated>' . date('c') . '</updated> 
       <author> 
        <name>' . $author_name . '</name> 
        <email>' . $author_email . '</email> 
       </author> 
       <id>tag:' . str_replace("http://", '', $site_domain) . ',2012:feed</id>'; 

      # Get the entries 


      foreach($rows as $row) { 
       $feed .= '<entry> 
        <title>' . $row->title . '</title> 
        <link href="' . strtolower($site_domain . DS . $row->category . DS . $row->permalink) . '" />'; 

        $date= date('Y-m-d', strtotime($row->timestamp)); 
        $uuid = str_replace("http://", '', $site_domain) . ',' . $date . ':' . $row->permalink; 

       $feed .= '<id>tag:' . $uuid . '</id>'; 

       if(isset($row->lastupdated)) { 
        $feed .= '<updated>' . date('c', strtotime($row->lastupdated)) . '</updated>'; 
       } 
       else { 
        $feed .= '<updated>' . date('c', strtotime($row->timestamp)) . '</updated>'; 
       } 

       $feed .= '<summary>Entry for ' . $date . '</summary> 
        <content type="xhtml" xml:lang="en"> 
         <div xmlns="http://www.w3.org/1999/xhtml">' . $row->abstract . '</div> 
        </content> 
       </entry>'; 
      } 

      $feed .= "</feed>"; 

      $path = ROOT . DS . "atom.xml"; 
      $filenum=fopen($path, "w"); 
      fwrite($filenum, $feed); 
      fclose($filenum); 
     } 
    } 

    # call this function wherever is relevent for you 
    publishAtom(); 
?> 

它應該給你一個關於如何手動完成的想法。 HTH。
