OK maybe someone can take a look what im doing wrong

PHP Code:

<?php

//#### Parser

function rss_parser($feedurl,$notmore)
    
    {
    include "inc/config.php";

    //get the simplepie library
    require_once('simplepie.inc');

    $dahtmlheader ="Content-Type: text/html\r\nContent-Transfer-Encoding: 8bit\r\n";

    //grab the feed
    $feed = new SimplePie();
    //enable caching
    $feed->enable_cache(false);
    //init the process
    $feed->init();
     //let simplepie handle the content type (atom, RSS...)
    $feed->handle_content_type();

    $i=0;

    if ($feed->error)
        {
        echo $feed->error;
        };
        
        
        $feedurlcheck = preg_replace("/[^0-9a-zA-Z]/","",$feedurl);
        if (strlen($feedurl) > 50) {$feedurlcheck = substr($feedurlcheck, 0, 50);};

        foreach ($feed->get_items(0, 1) as $item)
        
           {
              if($notmore < $i +1){break;};

              $title = $item->get_title();
              $description = $item->get_content();
              $url = $item->get_link();


                if(file_exists("save/".$feedurlcheck.".txt"))

                    {

                    $lastpost = file_get_contents("save/".$feedurlcheck.".txt");
                    if($lastpost == $title){break;};

                    };

                      echo $output;
                      echo "<div class='topicheader'><h3>".$title."</h3></div>";
                      echo "<div class='topicbody'>".$url."<div class='clear'></div></div>";


                      if($i == 0)

                     {

                       $newlastpostitle = $title;

                     };

                $i++;

                     };

                      if($lastpost != $title)

                    {

                      $fh = fopen("save/".$feedurlcheck.".txt", "w");
                      fputs($fh, $newlastpostitle);
                      fclose($fh);

            };

    }
?>

annnd, what is the error ?
Because, you know, without all the includes, libraries, db structure and that "useless" stuff, there's not really a way to guess where and what your error is...
