Kory-
All you need to do is the following:
1.) Request the two most recent tweets by setting rpp = 2, instead of one, in the query string.
2.) Then, in the parse_feed function, add an additional variable to extract the second tweet array element:
$tweet_array3 = explode( “”, $tweet_array[2] );
3.) You’ll next need to add another $tweet variable and process it in the same way as the first one–making sure that where ever there is a $tweet variable referenced, you create a new reference for $tweet2. This could be done via a loop if you wished.
$tweet2 = $tweet_array3[0];
… etcetera
4.) Finally, you’ll need to make sure that the new $tweet2 variable is returned and also is referenced in the list() function.
return array ( $tweet, $tweet2, $tweet_extra );
…
list ( $tweet, $tweet2, $tweet_extra ) = parse_feed( file_get_contents( $latest_tweet ) );
Style to your liking!
