Simple function to read RSS where you can set some values:

function rssReader($url,$maxItems=15,$begin="",$end=""){
        $rss = simplexml_load_file($url);
        $i=0;
        if($rss){
            $items = $rss->channel->item;
            foreach($items as $item){
                if($i==$maxItems) return $out;
                else $out.=$begin.''.$item->title.''.$end;
                $i++;
            }
        }
        return $out;
    }

Usage example:

echo '
'.rssReader('https://garridodiaz.com/feed/',5,'
','
').'
';

Using cache with the class fileCache:

 function rssReader($url,$maxItems=15,$cache,$begin="",$end=""){
        $cache= (bool) $cache;
        if ($cache){
            $cacheRSS= new fileCache();//seconds and path
            $out = $cacheRSS->cache($url);//getting values from cache
        }else $out=false;

        if (!$out) {	//no values in cache
            $rss = simplexml_load_file($url);
            $i=0;
            if($rss){
                $items = $rss->channel->item;
                foreach($items as $item){
                    if($i==$maxItems){
                        if ($cache) $cacheRSS->cache($url,$out);//save cache
                        return $out;
                    }
                    else $out.=$begin.''.$item->title.''.$end;
                    $i++;
                }
            }
        }
        return $out;
    }

Usage example RSS with cache:

echo '
'.rssReader('https://garridodiaz.com/feed/',5,true,'
','
').'
';

Based on this one from sihan:

 $url = "http://news.google.com/?ned=us&topic=t&output=rss";
    $rss = simplexml_load_file($url);
    if($rss){
        echo '
'.$rss->channel->title.'
';
        echo '
'.$rss->channel->pubDate.'
';
        $items = $rss->channel->item;
        foreach($items as $item){
            $title = $item->title;
            $link = $item->link;
            $published_on = $item->pubDate;
            $description = $item->description;
            echo '
'.$title.'
';
            echo '('.$published_on.')';
            echo '
'.$description.'
';
        }
    }
