无法在Windows上安装新客户端

我按照这里给出的说明在Windows 7上安装新客户端-https://github.com/neoxygen/neo4j-neoclient

但我得到了错误-

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

当我尝试运行示例php代码时。

我的代码是-

<?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;
?>
