Displaying Multiple RSS Feeds with PHP

问题

Does anyone know how to do this? I know how to display a single feed as a simple list, but it gets more complicated. I want to display a list but have multiple sources, with each source having the list-style-image be specific.

Example:

(img1) This is data from rss feed 1
(img2) This is data from rss feed 2

Thanks so much for the help!

This is what I have for a single source list.

# INSTANTIATE CURL.
$curl = curl_init();

# CURL SETTINGS.
curl_setopt($curl, CURLOPT_URL, "RSSURL");
curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($curl, CURLOPT_CONNECTTIMEOUT, 0);

# GRAB THE XML FILE.
$xmlTwitter = curl_exec($curl);

curl_close($curl);

# SET UP XML OBJECT.
$xmlObjTwitter = simplexml_load_string( $xmlTwitter );

$tempCounter = 0;

foreach ( $xmlObjTwitter->channel->item as $item )
{                    
    # DISPLAY ONLY 10 ITEMS.
    if ( $tempCounter < 11 )
    {
        echo "<li><a href=\"{$item -> guid}\">{$item -> title}</a></li>
";
    }

    $tempCounter += 1;
}

EDIT 1

Alright, Thanks a lot. Very helpful. I've attempted to implement it by: 1. Installing SimplePie into the root of my site in the PHP folder. 2. Implenting the given code. (No styling yet, want to get it functional first.)

My code currently is this:

<?php
require_once('/simplepie.inc');

$feed = new SimplePie();
$feed->set_feed_url(array('rss1', 'rss2'));
$feed->init();
$feed->handle_content_type();
foreach ($feed->get_items(0, 100) as $item) {
    $n = array_search($item->get_feed(), $feeds);
    echo '<li class="feed'.$n.'">'.$item->get_title().'</li>';
}
?>\

I'm getting this output on my site:

set_feed_url(array('http://vimeo.com/user/likes/rss', 'http://vimeo.com/user/videos/rss')); $feed->init(); $feed->handle_content_type(); foreach ($feed->get_items(0, 100) as $item) { $n = array_search($item->get_feed(), $feeds); echo ' '.$item->get_title().' '; } ?>\

I'm obviously doing something wrong, but am having trouble discovering what it is. Thanks again.

回答1:

It seems that you have two problems: aggregating multiple RSS feeds and then displaying them in a list.

1: Use SimplePie lib -- probably the simplest and best one for anything related to RSS. Might seem as an overkill for someone because of the file size, but anyway. It will also handle sorting by date for you. http://simplepie.org/

<?php
$feed = new SimplePie();
$feed->set_feed_url(array('http://rss1', 'http://rss2'));
$feed->init();
$feed->handle_content_type();
foreach($feed->get_items(0, 100) as $item) {
    $n = array_search($item->get_feed(), $feeds);
    echo '<li class="feed'.$n.'">'.$item->get_title().'</li>';
}
?>

2: What akamike said (and deleted?), but list style images can be a pain -- almost impossible to align. A more flexible solution would be to remove them and use background.

CSS:

li.feed1, li.feed2 {
    list-style: none;
    background-position: left center;
    background-repeat: no-repeat; 
}

li.feed1 { background-image: url(feed1icon.png); }
li.feed2 { background-image: url(feed2icon.png); }
