例1 MysqlndUhConnection::getLastMessage() example

<?php
class proxy extends MysqlndUhConnection {
 public function getLastMessage($res) {
   printf("%s(%s)\n", __METHOD__, var_export(func_get_args(), true));
   $ret = parent::getLastMessage($res);
   printf("%s returns %s\n", __METHOD__, var_export($ret, true));

mysqlnd_uh_set_connection_proxy(new proxy());

$mysqli = new mysqli("localhost", "root", "", "test");
