ROZWIĄZANY: RSS polskie znaki - zmiana kodowania

[neoxs]

Witajcie,

Mam problem z RSS i kodowaniem znaków. Mianowicie chcę aby na www.left4dead.org.pl pobierało mi z kanału RSS pewne informacje. Niestety RSS jest zapisane w UTF8 , a strona w ISO i teraz trzeba to w locie przekonwertować.Jednak nie wiem za bardzo jak.

Oto RSS: http://www.grasz.org/forum/index.php?/rss/forums/2-spolecznosc-left-4-dead/

Strona, która pobiera dane: http://www.left4dead.org.pl/ (jak widać krzaków w ostatnim newsie jest pełno).

Kiedyś uratowało mnie w innym skrypcie takie coś:

mb_convert_encoding($zmienna, "ISO-8859-2", "UTF-8");

Niestety teraz nie umiem sobie z tym poradzić.

Oto kod źródłowy skrypty pobierającego RSS:

<?php

class rss_parser {
 var $update_interval = 10;    
 /* How often to fetch the rss file
    A cached version will be used between updates    */

 var $data_directory = "/var/www/vhosts/left4dead.org.pl/httpdocs/zas";
 /* Where to store the rss data from the feeds
    Note: an absolute path is better than a relative path here
    unless you plan on keeping the script to display the feeds
    in the same folder as this file and the feeds.   */



 /* NO NEED TO EDIT BELOW HERE UNLESS YOU KNOW WHAT YOU ARE DOING  */


 var $rss_url;
 var $num_to_show;
 var $do_update;
 var $tags = array();
 var $content;
 var $rss = array();

 var $feed_title;
 var $feed_link;
 var $feed_description;

 var $my_html;


 function rss_parser($url, $numtoshow = 10, $html = "", $update = 0)
 {
   $this->rss_url = $url;
   $this->num_to_show = $numtoshow;
   $this->do_update = $update;
   $this->my_html = preg_replace("/(#{.*?).*?})/", "\\1__\\2", $html); //xx:xx tag workaround

   $this->content = $this->fetch_feed();
   $this->parse_feed();
   $this->show();

 }


 /* string */
 function fetch_feed()
 { 
   $url_parts = parse_url($this->rss_url);

   $filename = $url_parts['host'] . str_replace("/", ",", $url_parts['path']) . "_" . @$url_parts['query'];
   if(file_exists($this->data_directory . "/$filename")) {
     $last = filemtime($this->data_directory . "/$filename");
     if(time() - $last > $this->update_interval * 60 || $this->update_interval == 0) {
       $update = 1;
     }
   } else {
       $create= 1;
   }

   if($create == 1 || ($this->do_update == TRUE && $update == 1)) {
     $fp = @fsockopen($url_parts['host'], 80, $errno, $errstr, 5);
     if (!$fp) {
       echo "Couldn't open rss feed {$this->feed_url} in {$_SERVER['PHP_SELF']}<br />\n";
       return;
     }

     fputs($fp, "GET " . $url_parts['path'] . "?" . @$url_parts['query'] . " HTTP/1.0\r\n"
               ."Host: " . $url_parts['host'] . "\r\n"
               ."User-Agent: Drew's RSS Reader 0.1\r\n"
               ."Connection: Close\r\n\r\n");

     while(!feof($fp)) {
       $rss_data .= @fgets($fp, 1024);
     }

     list(, $rss_data) = explode("\r\n\r\n", $rss_data, 2);

     $output = @fopen($this->data_directory . "/$filename", "w+");
     if(!$output) {
       return $rss_data;
     } else {
       flock($output, LOCK_EX);
       fputs($output, $rss_data);
       flock($output, LOCK_UN);
       fclose($output);
     }
   } //update

   return file_get_contents($this->data_directory . "/$filename");

 }

 /* void */
 function parse_feed()
 {
   preg_match("/<title>(.*?)<\/title>/", $this->content, $title);
   $this->feed_title = @$title[1];

   preg_match("/<link>(.*?)<\/link>/", $this->content, $link);
   $this->feed_link = @$link[1];

   preg_match("/<description>(.*?)<\/description>/", $this->content, $description);
   $this->feed_description = @$description[1];
  mb_convert_encoding($description[1], "ISO-8859-2", "UTF-8");
    preg_match_all("/<item[^>]*>(.*?)<\/item>/s", $this->content, $items);
   if (sizeof($items[0]) == 0) {
     echo "No item elements found in rss feed.<br />\n";
   }

   for($i = 0; $i < sizeof($items[0]); ++$i) {
     preg_match_all("/(?:<([\w:]*)[^>]*>(?:<!\[CDATA\[)?(.*?)(?:]]>)?<\/\\1>)+?/si", preg_replace("/<item[^>]*>/", "", $items[0][$i]), $elements);
     for($j = 0; $j < sizeof($elements[0]); ++$j) {
       $elements[1][$j] = str_replace(":", "__", $elements[1][$j]);  //regex fix for items with : like dc:date
       $this->rss[$i][$elements[1][$j]] = trim(html_entity_decode($elements[2][$j]));
     }
   }

 }


 /* void */
 function show()
 {

   if($this->my_html == "") {
     $this->show_html();
   } else {
     $this->show_user_html();
   }
 }

 function show_html()
 {
   $show = (sizeof($this->rss)  > $this->num_to_show ? $this->num_to_show : sizeof($this->rss));
   for($i = 0; $i < $show; ++$i) {
     echo "- <a href=\"{$this->rss[$i]['link']}\" target=\"_new\">{$this->rss[$i]['title']}</a><br />\n";
   }
 }

 function show_user_html()
 {
   $show = (sizeof($this->rss) > $this->num_to_show ? $this->num_to_show : sizeof($this->rss));
   for($i = 0; $i < $show; ++$i) {
     extract($this->rss[$i]);
     $item = preg_replace("/#\{([^}]+)}/e", "$\\1", $this->my_html);
     echo $item;
   }
 }

} // end class


?>

A to kod, który służy za wyświetlanie:

<?php

include_once "./zas/rss_fetch.php";


$html  = "  <div><table cellpadding='0' cellspacing='0' align='center' width='600'><tr>
<td style='background:url(../images/newsa.gif); height: 50px; width: 600px; background-repeat: no-repeat;'>\n";
$html .= "    <div style='font-size: 13px; color: #E6E6E6; margin-left: 8px; margin-top: 5px;'><a href='#{link}' ><b>#{title}</b></a></div>\n";
$html .= "     <div style='font-size: 10px; color: #E6E6E6; margin-left: 8px; margin-top: 5px;'> Opublikowano: #{pubDate}</div></td></tr>";
$html .= "      <tr><td><div style='font-size: 11px; color: #CBCBCB; margin-left: 4px; margin-top: 5px; margin-bottom: 10px; text-align:justify;'>

$rss = new rss_parser("http://www.grasz.org/forum/index.php?/rss/forums/2-spolecznosc-left-4-dead/", 5, $html, 1);

?>

Temat do zamknięcia, już sobie poradziłem. Po prostu użyłem innego parsera rss i go trochę przerobiłem -> http://www.acornartwork.com/blog/2010/04/03/tutorial-rss-feed-parser-in-pure-php/
