`<?php
class proxy extends MysqlndUhConnection {
public function getSqlstate($res) {
printf("%s(%s)\n", __METHOD__, var_export(func_get_args(), true));
$ret = parent::getSqlstate($res);
printf("%s returns %s\n", __METHOD__, var_export($ret, true));
return $ret;
}
}
mysqlnd_uh_set_connection_proxy(new proxy());
$mysqli = new mysqli("localhost", "root", "", "test");
var_dump($mysqli->sqlstate);
$mysqli->query("AN_INVALID_REQUEST_TO_PROVOKE_AN_ERROR");

?>`

    proxy::getSqlstate(array (
      0 => NULL,
    ))
    proxy::getSqlstate returns '00000'
    string(5) "00000"
    proxy::getSqlstate(array (
      0 => NULL,
    ))
    proxy::getSqlstate returns '42000'
    string(5) "42000"
