Question

how to add an offset and limit to my PHP rss parser that returns the result as an object ?, here is what i have at the moment. it doesn’t have any offset nor limit, how to approach this ?

    class Rss
{
     /*
     *@access public
     *@params url,int ''=default,int ''=default
     *@usage input url,offset and limit,
     *@returns content based onf the offset/limit input
     */
    public function getFeed($url,$offset='',$limit=''){
        $object = array();
        $rss = simplexml_load_file($url);
      foreach($rss->channel->item as $item){
          $object[] = $item->title;
          $object[] = $item->description;
          $object[] = $item->link;
      }
     return $object;
   }
}

Simpliest way

$limit = 10; $offset = 5; 
$i=0; $taken=0;
foreach($rss->channel->item as $item){
    if ($i>=$offset && $taken<$limit){
        ++$taken;
        $object[] = $item->title;
        $object[] = $item->description;
        $object[] = $item->link;
    }
    //little optimization here
    if ($taken == $limit)
        break;
    ++$i;
}

Of course you can store $limit and $offset as object properties, or get them elsewhere.
