Error in a class

[axmug]

Hi,

I have an error in a class I typed, and I don't know why. My code is the following:

class Persona
{
        private $nombre;
        private $apellidos;

    function __construct()
     {
            $nombre="David";
            $apellidos="Garcia Roma";       
     }

    function getNombre()
     { 
            return $nombre."<br>";
     }

    function getApellidos()
     { 
            return $apellidos."<br>";
     }

};

$persona = new Persona();
print $persona->getNombre();

When I load the script in my webserver I display the following error:

Undefined variable: nombre in C:\wamp\www\DatosPersonas.php on line 33

How can I fix this error?

Thanks.

        function __construct()
         {
                $this->nombre="David";
                $this->apellidos="Garcia Roma";       

         }
