class MyEntry extends Zend_Feed_Entry_Atom
{

    public function __construct($uri = 'http://www.example.com/myfeed/',
                                $xml = null)

                return parent::__get('myns:updated');

            default:
                return parent::__get($var);

    }

    public function __set($var, $value)
    {
        switch ($var) {
            case 'myUpdated':
                // Translate myUpdated to myns:updated.
                parent::__set('myns:updated', $value);
                break;

            default:
                parent::__set($var, $value);
        }
    }
    
    public function __call($var, $unused)
    {
        switch ($var) {
            case 'myUpdated':
                // Translate myUpdated to myns:updated.
                return parent::__call('myns:updated', $unused);

            default:
                return parent::__call($var, $unused);
        }
    }
}   
        

接下来你就可以直接实例化和设置myUpdated属性来使用这个类：

<?php
$entry = new MyEntry();
$entry->myUpdated = '2005-04-19T15:30';

// method-style call is handled by __call function
$entry->myUpdated();  
// property-style call is handled by __get function
$entry->myUpdated;
