Невозможно установить neoclient в Windows

Я следую приведенным здесь инструкциям по установке neoclient на Windows 7 —
https://github.com/neoxygen/neo4j-neoclient

Но я получаю ошибку —

<b>Parse error</b>:  syntax error, unexpected 'use' (T_USE) in <b>C:\xampp\htdocs\send.php</b> on line <b>7</b><br />

когда я пытаюсь запустить пример PHP-кода.

Мой код —

<?php
try
{
require_once 'vendor/autoload.php';

use Neoxygen\NeoClient\ClientBuilder;

$client = ClientBuilder::create()
->addConnection('default','http','localhost',7474)
->build();

$version = $client->getNeo4jVersion();
}
catch(Exception $e)
{
echo $e->getMessage();
}

echo $version;

?>
