my goal is to access the content of myUser.class.php (located in the lib dir) from a template or layout. But how can I do that?

My myUser.class.php file:

class myUser extends sfBasicSecurityUser
{

        public function getTestData()
        {
                return "test-text";
        }
}

> Try this in your template :
>
> $sf_user->getTestData( )
