Example code to layout tweets

Thanks very much to Emma from Red Earth Design for sending us this example code to layout tweets in a way that meets Twitters display guidelines.

// draft sample display for array returned from oAuth Twitter Feed for Developers WP plugin
// http://wordpress.org/extend/plugins/oauth-twitter-feed-for-developers/

$tweets = getTweets(1, 'twitter_username_here');//change number up to 20 for number of tweets
if(is_array($tweets)){

// to use with intents
echo '<script type="text/javascript" src="//platform.twitter.com/widgets.js"></script>';

foreach($tweets as $tweet){

    if($tweet['text']){
        $the_tweet = $tweet['text'];
        /*
        Twitter Developer Display Requirements
        https://dev.twitter.com/terms/display-requirements

        2.b. Tweet Entities within the Tweet text must be properly linked to their appropriate home on Twitter. For example:
          i. User_mentions must link to the mentioned user's profile.
         ii. Hashtags must link to a twitter.com search with the hashtag as the query.
        iii. Links in Tweet text must be displayed using the display_url
             field in the URL entities API response, and link to the original t.co url field.
        */

        // i. User_mentions must link to the mentioned user's profile.
        if(is_array($tweet['entities']['user_mentions'])){
            foreach($tweet['entities']['user_mentions'] as $key => $user_mention){
                $the_tweet = preg_replace(

        //    No other social or 3rd party actions similar to Follow, Reply, Retweet and Favorite may be attached to a Tweet.

        // 5. Tweet Permalink
        //    The Tweet timestamp must always be linked to the Tweet permalink.
