我需要一个帮助，我有一个主题，在我有一个twitter小部件的地方，我只想把它分开，并保存在不同的文件中，就像它是一个插件一样，下面是完整的代码，我要做什么？

此代码在文件中admin-functions.php

/*-----------------------------------------------------------------------------------*/
/* Twitter\'s Blogger.js output for Twitter widgets */
/*-----------------------------------------------------------------------------------*/

function woo_twitter_script($unique_id,$username,$limit) {
?>
<script type="text/javascript">
<!--//--><![CDATA[//><!--

    function twitterCallback2(twitters) {
      var statusHTML = [];

这是我在theme-widget.php

       $widget_ops = array(\'description\' => \'Add your Twitter feed to your sidebar with this widget.\' );
       parent::WP_Widget(false, __(\'Woo - Twitter Stream\', \'woothemes\'),$widget_ops);      
   }

   function widget($args, $instance) {  
    extract( $args );

      <?php
   }

} 
register_widget(\'Woo_Twitter\');

我只想把这段代码变成一个不同的文件，就像一个插件，这样我就可以在我的另一个主题中使用它，这里有人能帮我吗？？？
