 public function stmtInit($res) {
  printf("%s(%s)\n", __METHOD__, var_export(func_get_args(), true));
  var_dump($res);
  $ret = parent::stmtInit($res);
  printf("%s returns %s\n", __METHOD__, var_export($ret, true));
  var_dump($ret);
  return $ret;
 }
}
mysqlnd_uh_set_connection_proxy(new proxy());
$mysqli = new mysqli("localhost", "root", "", "test");
$stmt = $mysqli->prepare("SELECT 1 AS _one FROM DUAL");
$stmt->execute();
$one = NULL;
$stmt->bind_result($one);
$stmt->fetch();
var_dump($one);
?>
