TalkPHP - Good or Bad Code

Can you please take look at these to 3 files.
though I get the result I want,I am not sure it is a good or Bad Code.

PHP Code:


		
			
<?php

 /*

  * File:menu.cls.php

  * Folder:classes

  * 

  */



require("includes/configs.php");





  class Menu {

      

    public $result;

    

    public $connDB;

        public function __construct(){

          global $config;

        $host = $config['db']['host'];

        $user = $config['db']['user'];

        $pass = $config['db']['pass'];

        $this->connDB = new PDO($host,$user,$pass);

      }

      public function showMenu(){

      

        

        $conn = $this->connDB->query("select * from menu");

        while($res = $conn->fetch(PDO::FETCH_ASSOC)){

            $this->result[] = $res;

        }

        $this->result;

      } 



  }

  



?>

PHP Code:


		
			
<?php

    /*

     * File:config.php

     * Folder:includes

     *  

     */

    $config['db']['host'] = "mysql:host=localhost;dbname=gry";

    $config['db']['user'] = "root";

    $config['db']['pass']="";

    $config['site']['name'] = "Gallery";

?>

PHP Code:


		
			
<?php

/*

 * File:index.php

 * Folder:root

 */

require("classes/menu.cls.php");

$new = new Menu;

$new->showMenu();



echo "<ul style=padding=50px>";

foreach ($new->result as $key){

echo "<li style=display:inline;padding:5px;text:none;><a href='".$key['url']."'>\t".$key['name']."</a></li>";

}

echo "</ul>";

?>
