### Examples

Example #1 MysqlndUhConnection::useResult() example

`<?php
class proxy extends MysqlndUhConnection {
public function useResult($res) {
printf("%s(%s)\n", __METHOD__, var_export(func_get_args(), true));
$ret = parent::useResult($res);
printf("%s returns %s\n", __METHOD__, var_export($ret, true));
var_dump($ret);
return $ret;
}
}
mysqlnd_uh_set_connection_proxy(new proxy());
$mysqli = new mysqli("localhost", "root", "", "test");
$mysqli->real_query("SELECT 'Good morning!' AS _msg FROM DUAL");
$res = $mysqli->use_result();
var_dump($res->fetch_assoc());
?>`

The above example will output:

    proxy::useResult(array (
      0 => NULL,
    ))
    proxy::useResult returns NULL
    resource(425) of type (Mysqlnd Resultset (internal only - you must not modify it!))
    array(1) {
      ["_msg"]=>
      string(13) "Good morning!"
    }
