注册表设计模式......好还是坏?

I just want to figure out if I should use this design pattern in my own implementation of a MVC framework. Thanks!

<?php
/**
 * The PCARegistry object
 * Implements the Registry and Singleton design patterns
 * @version 0.1
 * @author Michael Peacock
 */
class PCARegistry {

/**
 * Our array of objects
 * @access private
 */
private static $objects = array();

/**
 * Our array of settings
 * @access private
 */
private static $settings = array();

/**
 * The frameworks human readable name
 * @access private
 */
private static $frameworkName = 'PCA Framework version 0.1';

/**
 * The instance of the registry
 * @access private
 */
private static $instance;

/**
 * Private constructor to prevent it being created directly
 * @access private
 */
private function __construct()
{

}

/**
 * singleton method used to access the object
 * @access public
 * @return 
 */
public static function singleton()
{
    if( !isset( self::$instance ) )
    {
        $obj = __CLASS__;
        self::$instance = new $obj;
    }

    return self::$instance;
}

/**
 * prevent cloning of the object: issues an E_USER_ERROR if this is attempted
 */
public function __clone()
{
    trigger_error( 'Cloning the registry is not permitted', E_USER_ERROR );
}

/**
 * Stores an object in the registry
 * @param String $object the name of the object
 * @param String $key the key for the array
 * @return void
 */
public function storeObject( $object, $key )
{
    require_once('objects/' . $object . '.class.php');
    self::$objects[ $key ] = new $object( self::$instance );
}

/**
 * Gets an object from the registry
 * @param String $key the array key
 * @return object
 */
public function getObject( $key )
{
    if( is_object ( self::$objects[ $key ] ) )
    {
        return self::$objects[ $key ];
    }
}

/**
 * Stores settings in the registry
 * @param String $data
 * @param String $key the key for the array
 * @return void
 */
public function storeSetting( $data, $key )
{
    self::$settings[ $key ] = $data;


}

/**
 * Gets a setting from the registry
 * @param String $key the key in the array
 * @return void
 */
public function getSetting( $key )
{
    return self::$settings[ $key ];
}

/**
 * Gets the frameworks name
 * @return String
 */
public function getFrameworkName()
{
    return self::$frameworkName;
}


}
