probleme connec

bonjour,

j'ai cette erreur en faisant le tuto sécuriser les sessions pourtant en local pas de soucis

Parse error: syntax error, unexpected T_STATIC, expecting T_OLD_FUNCTION or T_FUNCTION or T_VAR or '}' in /homepages/17/d353355229/htdocs/admin/auth.php on line 3

le code :

<?php
class Auth{
    static function isLogged(){
        if(isset($_SESSION'Auth']) && isset($_SESSION'Auth']'login']) && isset($_SESSION'Auth']'pass'])){
            extract($_SESSION'Auth']);
            mysql_connect("plop","plop","plop");
            mysql_select_db("db364970605");
            $sql = " SELECT id FROM admin WHERE login='$login' AND pass='$pass'";
            $req = mysql_query($sql) or die(mysql_error());
            if(mysql_num_rows($req)>0){
                return true;
            }
            else{
                return false;
            }
        }   
        else{
            return false;
        }
    }
}
?>

cordialement
