<?php
class proxy extends MysqlndUhConnection {
public function connect($res, $host, $user, $passwd, $db, $port, $socket, $mysql_flags) {
printf("%s(%s)\n", __METHOD__, var_export(func_get_args(), true));
$ret = parent::connect($res, $host, $user, $passwd, $db, $port, $socket, $mysql_flags);
printf("%s returns %s\n", __METHOD__, var_export($ret, true));
return $ret;
}
}
mysqlnd_uh_set_connection_proxy(new proxy());
$mysqli = new mysqli("localhost", "root", "", "test");
?>
