Example #1 MysqlndUhConnection::getSqlstate() example

<?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);
$mysqli->query("AN_INVALID_REQUEST_TO_PROVOKE_AN_ERROR");
var_dump($mysqli->sqlstate);
?>

以上例程会输出：

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