Ayuda con Array

[Nillus]

Hola,
le he estado dando vueltas a este array pero por mas que me lo plantee no consigo dar con la forma en la que funciona

Les agradeceria que me lo explicaran.

Necesito que me expliquen solo la función user

éste es el array:

Código PHP:

function user($key){
        switch($key){
            case "id":
                $value = $this->user[0]; break;
            case "name":
                $value = $this->user[1]; break;
            case "password":
                $value = $this->user[2]; break;
            case "rank":
                $value = $this->user[3]; break;
            case "birth":
                $value = $this->user[5]; break;
            case "figure":
                $value = $this->user[6]; break;
            case "sex":
                $value = $this->user[7]; break;
            case "mission":
                $value = $this->user[8]; break;
            case "credits":
                $value = $this->user[9]; break;
            case "tickets":
                $value = $this->user[10]; break;
            case "ticket_sso":
                $value = $this->user[11]; break;
            default:
                $value = $GLOBALS['serverdb']->result($GLOBALS['serverdb']->query("SELECT ".$key." FROM ".PREFIX."users WHERE id = '".$this->user[0]."' LIMIT 1")); break;
        }
        return $value;
    }
 

y ésta es la class completa:

Código PHP:

class HoloUser {
    var $id = 0; var $name = "Guest"; var $password = null; var $logged_in = false; var $ip = null; var $time = null;
    var $error = 0; var $banned; var $user = array('0','Guest','null','0',null,null,null,null,null,null,null,null,null);
    function HoloUser($name,$password,$updateuser=false,$rememberme=null){
        $data = new index_sql;
        $date = HoloDate();
        if(empty($name) || empty($password)){
            $this->error = 1; return false;
        }
        if($GLOBALS['serverdb']->num_rows($data->select1($name, $password)) < 1){
            $this->error = 2; return false;
        }
        $id = $GLOBALS['serverdb']->result($data->select1($name, $password));
        if($this->IsUserBanned($id) == true){
            $row = $GLOBALS['serverdb']->fetch_row($GLOBALS['core']->select2($id));
            $this->banned['reason'] = $row[0];
            $this->banned['expire'] = $row[1];
            $this->error = 3; return false;
        }
        if($this->error == 0 && !is_array($this->banned)){
            $this->ip = $_SERVER['REMOTE_ADDR'];
            if($rememberme == "true"){
                $token = GenerateTicket("remember");
                $GLOBALS['serverdb']->query("UPDATE ".PREFIX."users SET remember_token = '".$token."' WHERE id = '".$id."' LIMIT 1");
                setcookie("rememberme", "true", time()+60*60*24*$GLOBALS['settings']->find("site_cookie_time"), "/");
                setcookie("rememberme_token", $token, time()+60*60*24*$GLOBALS['settings']->find("site_cookie_time"), "/");
            }
            if($updateuser == true){ $this->updateUser($id); }
            $this->user = $GLOBALS['serverdb']->fetch_row($GLOBALS['core']->select3($id)); $this->id = $id; $this->name = $this->user("name"); $this->figure = $this->user("figure"); $this->password = $password; $this->logged_in = true;
        }
        $this->time = time();
        return true;
    }
    function destroy(){
        @session_start();
        setcookie("rememberme", "", time()-60*60*24*100, "/"); setcookie("cookpass", "", time()-60*60*24*100, "/");
        setcookie("rememberme_token", "", time()-60*60*24*100, "/"); setcookie("cookpass", "", time()-60*60*24*100, "/");
        $_SESSION = array();
        if(isset($_COOKIE[session_name()])) { setcookie(session_name(), "", time()-60*60*24*100, "/"); }
        @session_destroy();
        return true;
    }
    function refresh(){
        $GLOBALS['user'] = new HoloUser($this->name,$this->password);
        $_SESSION['user'] = $GLOBALS['user'];
        return true;
    }
    function user($key){
        switch($key){
            case "id":
                $value = $this->user[0]; break;
            case "name":
                $value = $this->user[1]; break;
            case "password":
                $value = $this->user[2]; break;
            case "rank":
                $value = $this->user[3]; break;
            case "birth":
                $value = $this->user[5]; break;
            case "figure":
                $value = $this->user[6]; break;
            case "sex":
                $value = $this->user[7]; break;
            case "mission":
                $value = $this->user[8]; break;
            case "credits":
                $value = $this->user[9]; break;
            case "tickets":
                $value = $this->user[10]; break;
            case "ticket_sso":
                $value = $this->user[11]; break;
            default:
                $value = $GLOBALS['serverdb']->result($GLOBALS['serverdb']->query("SELECT ".$key." FROM ".PREFIX."users WHERE id = '".$this->user[0]."' LIMIT 1")); break;
        }
        return $value;
    }
}
 

Muchas gracias
