无法在Windows上安装neoclient

Question

我按照这里给出的指示在Windows 7- https://github.com/neoxygen/neo4j-neoclient上安装neoclient

但我明白错误-

<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。

我的密码是-

<?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;

?>

我是NeoClient的维护者。

我想我从来没有见过这段代码，请指向一个链接。

特别是，require和use语句应该在文件的开头，在open tag之后。

其次，您不需要在try/catch块中实例化客户机。

以下是正确的代码：

<?php

require_once 'vendor/autoload.php';

use Neoxygen\NeoClient\ClientBuilder;

$client = ClientBuilder::create()
->addConnection('default','http','localhost',7474)
->build();
try
{
    $version = $client->getNeo4jVersion();
}
catch(Exception $e)
{
    echo $e->getMessage();
}
echo $version;
?>
