Redeclare Problem

Hi i have this kind of script for CI

<?php if (!defined('BASEPATH')) exit('No direct script access allowed');

class Widget
{
    public $module_path;
    
    function run($file) {        
        $args = func_get_args();

        $module = '';
        
        /* is module in filename? */
        if (($pos = strrpos($file, '/')) !== FALSE) {
            $module = substr($file, 0, $pos);
            $file = substr($file, $pos + 1);
        }
        

            include './application/widgets/'.$file.".php";
            $file = ucfirst($file);
          
            $widget = new $file();
            global $widget;
            $widget->module_path = $path;    
            
        return call_user_func_array(array($widget, 'run'), array_slice($args, 1));    
    }
    
    function render($view, $data = array()) {
        extract($data);
        include './application/widgets/views/'.$view.EXT;
    }

    function load($object) {
        $this->$object = load_class(ucfirst($object));
    }

    function __get($var) {
        global $CI;
        return $CI->$var;
    }
}

SO it load class and then run it. The problem when i run script once it fine. But when i run script second time with the same class name it give me error Fatal error: Cannot redeclare class Banners in /httpdocs/application/widgets/banners.php on line 20

So question is it any way to make class end and then run again.
