PHP Code:

// The array below are the ids of non-public forums, update these to be your admin forum ids or anything non-public by default
$excludedForums = array(18, 19, 23, 37);

// If you are having trouble getting bitly URL shortening to work... disable it!
$useBitly = true;

if (!in_array($foruminfo[forumid], $excludedForums)) {
    $shortUrl = 'http://www.babaforum.com/showthread.php?t='.$newpost[threadid];

    if ($useBitly) {
      // http://classes.verkoyen.eu/bitly
      require_once 'bitly.php';
      $bitly = new Bitly('BitlyName', 'BitlyAPiKey');
      $shortUrl = $bitly->shorten($shortUrl);
    }

    $tweet = '';
    if (isset($newpost['prefixid']) && $newpost['prefixid'] != '') {
        $tweet = $vbphrase['prefix_'.$newpost['prefixid'].'_title_plain'].' ';
    }
    $tweet .= $newpost['title'].' '.$shortUrl;

    // http://classes.verkoyen.eu/twitter/
    require_once 'twitter.php';
    $twitter = new Twitter('Twitteracc','TwitterPass');
    $twitter->updateStatus($tweet);
} 


This is my Plugin Code.But not working.Do you see any mistake?

Not: i didn't write my own twitter account name and password, at the same time bitly account name and api key also.
bitly.php and twitter.php are in my forum root folder.
