Добрый день!
пытаюсь вернуть на главной значение $authorization;

     $authorization = new authorization();
     echo $authorization->$authorization.'9898';

выдает
Catchable fatal error: Object of class authorization could not be converted to string in

класс

class authorization{
var $uid;
var $email;
var $password;
var $salt;
var $key;
var $law;
var $name;
var $phone;  
public  $admin;
public  $authorization;

function __construct(){ session_start();
$id = $_SESSION['id'];
$law = $_SESSION['law'];
$name = $_SESSION['name'];
$password = $_SESSION['password'];
$ip=$_SERVER['REMOTE_ADDR'];
$id=htmlspecialchars($id);
$id=htmlentities($id);
$law=htmlspecialchars($law);
$law=htmlentities($law);
$password=htmlspecialchars($password);
$password=htmlentities($password);
$name=htmlspecialchars($name);
$name=htmlentities($name);
$ip=htmlspecialchars($ip);
$ip=htmlentities($ip);
$mysql = new mysql();
$total = $mysql->get_query_total("SELECT * FROM  `".BCRM."user` WHERE `uid` = '".$id."' AND `law` = '".$law."' AND `name` = '".$name."'");
$sql = $mysql->get_query_simple("SELECT * FROM  `".BCRM."user` WHERE `uid` = '".$id."' AND `law` = '".$law."' AND `name` = '".$name."'");
while ($row=mysql_fetch_array($sql))
{$pass == $row['password'];}
if($total == 1 and $password == md5(sha1($pass + md5(sha1($ip))))){$this->authorization ='yes';}else{$this->authorization ='no';session_destroy();}
return  $this->authorization;}}

объясните пожалуйста где я ошибся.
