Help with object values

[eluser]Rubiz'[/eluser]
Hi! I had never worked with PHP with Arrays and Objects, I'm a little bit "lost" in values and how to get them. So, I have:

Code:

function name ()
{
  $data['name'] = 'Rubia';
  $data['last_name'] = 'Gardini';

  $this->registrate($data);
}

In the function "registrate", how can I get this values?
