使用simplepie和codeigniter列出特定Feed类型旁边的设置图标

I have a small issue which I'm hoping someone can help me resolve.

Copied below is a piece of code which goes away to my database model and returns an array with a URL and a feed type. The user enters whether they have used a twitter name, blogger site etc.

However, to parse this data with simplepie I need to pass an array of URL's... and I lose my "type" option. Is there anyway I could add this back to the simplepie item so that I can display a specific icon if the user has selected a specific type of feed.

$feed = $this->profile_model->get_module_feed();

    $feedarr = array();
    foreach($feed['data'] as $feeds) {
        if ($feeds['type'] == 1 ) {
            $i = "http://api.twitter.com/1/statuses/user_timeline.rss?screen_name=" . $feeds['rss'];
        }
        if ($feeds['type'] == 2 ) {
            $i = "http://search.twitter.com/search.atom?q=" . $feeds['rss'];
        }
        if ($feeds['type'] >= 3 ) {
            $i = $feeds['rss'];
        }

        $d = $feeds['type'];

        //else $i = $feeds['rss'];

        echo $i . " " . $d . "<br />";

        array_push($feedarr, $i);
    }

    $this->simplepie->set_feed_url($feedarr);
    $this->simplepie->enable_cache(false);
    $this->simplepie->init();
    $this->simplepie->handle_content_type();


    $data = $this->simplepie;

    foreach($data->get_items() as $item) { ?>
        <h2><a href="<?php echo $item->get_permalink(); ?>"><?php echo $item->get_title(); ?></a></h2>
        <p><?php echo $item->get_description(); ?></p>
        <p><small>Posted on <?php echo $item->get_date('j F Y | g:i a'); ?></small></p>
    <?php


    }


    }
}


?>

Eg, if the $feed['type'] is 1 I would like to display the image associated with 1

hoping someone can help as I'm a wee bit stumped!

    You can use the individual feed item's feed property to get it's subscribe url and try to match it with the feed urls you used for the fetching. Here's a simplified example:

    // array with unique feed url => feed type (icon)
    $feed_types = array(
        'http://feed.one.com/' => 'type1',
        'http://feed.two.com/' => 'type2',
    );
    
    $pie = new SimplePie;
    $pie->set_feed_url(array_keys($feed_types));
    $pie->enable_cache(false);
    $pie->init();
    $pie->handle_content_type();
    
    foreach ($pie->get_items() as $item) {
        $feed_url = $item->feed->subscribe_url();
        $type = isset($feed_types[$feed_url]) ? $feed_types[$feed_url] : 'unknown type';
        print $type;
    }
    

    As long as you use the same url's for fetching that embedded into the feed results the subscribe_ul() method's result should align up with the urls used in set_feed_url().
