Je suis incapable d'obtenir un résultat de mes requêtes MySQL avec PHP

$newcomment = $two->newcomment($user);
          echo $newcomment['new'];

function newcomment($user){
        $user= mysql_real_escape_string($user);
   $q = "SELECT * FROM ".mine." WHERE u = '$user' AND new = 'new' LIMIT 1";
      $result = mysql_query($q, $this->connection);
      /* Error occurred, return given name by default */
      if(!$result || (mysql_numrows($result) < 1)){
   return NULL;
  }
  return $result;
