Building a simple Twitter widget using RSS

Sometimes, Twitter’s “stock” widgets aren’t quite what you want.

Sure, they look pretty nice; I’m even using one on this blog. But if you want to integrate Twitter info into an existing website, they don’t cut it. What then?

There’s the Twitter API. If you want to build any type of complex Twitter app/widget, then that might be the right solution for you, but if you want only to display simple, publicly-available tweets, then you can build your own widget using publicly-available Twitter RSS feeds.

Check out your own feed!

To see the feed for your own tweets, visit your Twitter profile using the old Twitter interface (I’m not sure where to find the RSS URL in the new UI). Below the icons of your followers, you should see a link to an RSS feed of your tweets:

Copy that URL: you’ll need it later.

Get coding!

I’m going to cover building a widget using PHP. If you prefer another language, I’m sure you can figure it out.

The first step is to determine how you will fetch and parse the RSS feed. I use Magpie RSS for this task. There are newer libraries for PHP available, but Magpie is simple and works.

Let’s take a look at my own widget (see my homepage):


    require('tp/magpierss/'); // using Magpie RSS

    // get the latest tweet via RSS
    $url = '';
    $latest_tweet = fetch_rss($url)->items[0]['title'];

    // we'll replace some patterns in the tweet
    $patterns = array(); $replacements = array();

    $patterns[] = '/curtisafree: /'; // remove Twitter username
    $replacements[] = '';

    $patterns[] = '/(https?:\/\/[^ ]+)/'; // make URLs into links
    $replacements[] = '<a href="\1">\1</a>';

    $patterns[] = '/@([a-zA-Z0-9_]+)/'; // turn user references into links
    $replacements[] = '<a href="\1">@\1</a>';

    echo preg_replace($patterns, $replacements, $latest_tweet);


The first task is to import the Magpie code. My path (tp/magpierss/ will only be valid if that is where you have placed the code within your website hierarchy. Adjust the path as appropriate.

Then, we actually fetch the information from Twitter. (Note that Magpie RSS uses caching, so the load you’ll be placing on the Twitter servers isn’t too bad; but if you expect very heavy traffic, you might consider using the official API instead.)

Magpie makes this simple. Using the URL you found earlier, we simply fetch the first tweet in the feed. Within the RSS entry, both the title and body give the actual tweet text – so either should do the trick. I chose to pull out the title.

You could stop here, if you wanted. You have the tweet text and can display it as you wish. I continue with some embellishments, though.

$patterns gives patterns to find within the tweet, and $replacements gives the corresponding replacement patterns (yep, PHP’s preg_replace can handle sets of patterns and their corresponding replacements!).

First, I remove my own Twitter username from the beginning of the tweet (there’s no need to show it).

Now, there are two types of links within a tweet that I’d like to represent as actual links: Twitter usernames (@username) and actual URLs. This can be accomplished using the patterns/replacements on lines 10-13.

You might have noticed in the newer Twitter UI that some tweets contain links without the protocol (http/https). The RSS feed, though, is more like the old Twitter UI. You’ll see full URLs. For example, I tweeted about recently, and you can see a difference in UIs (old on left, new on right):

Via RSS, you’ll see the former – so the regex I provided above should be sufficient.

And there you have it: a simple Twitter widget that you can place anywhere on your website.

Update (30 Jun 2012):

I actually haven’t been using this widget for a while. I had Twitter’s official “profile widget” on the site for a bit, but at present I have no elements pulling from Twitter.
