public function getErrorNumber($res) {
printf("%s(%s)\n", __METHOD__, var_export(func_get_args(), true));
$ret = parent::getErrorNumber($res);
printf("%s returns %s\n", __METHOD__, var_export($ret, true));
return $ret;
}

mysqlnd_uh_set_connection_proxy(new proxy());
printf("connect...\n");
$mysqli = new mysqli("localhost", "root", "", "test");
