Give a function a unique ID

Question

I'm developing a theme that uses a Twitter Tweets custom widget (Not coded by me). There are several widget areas within the theme and if I try and include the Twitter widget in say the sidebar and the footer at the same time I get this error;

Fatal error: Cannot redeclare echo_tweets_js() (previously declared in..... on line..... 

This is the section of offending code;

function echo_tweets_js() {
        global $pt_twitter_username, $pt_twitter_postcount;
        echo pt_twitter_js($pt_twitter_username, $pt_twitter_postcount);
    }

    add_action('wp_footer', 'echo_tweets_js', 9999);

Is there a way I can make it work if a user decides they want it in 2 places at the same time?

Just... call the function again - you only need to include it once!

include './path/to/lib.php';

echo_tweet_js(); // a little tweeting here

...

echo_tweet_js(); // and a little tweeting over here!
