无法在Windows

Question

安装neoclient

我下面这里给出的方向上的Windows 7安装neoclient - https://github.com/neoxygen/neo4j-neoclient

但我得到的错误 -

<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PHP示例码。

我的代码 -

<?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; 

?> 

composer.json -

我NeoClient的维护者。

我不认为我曾经在某处看过这段代码，请指向一个链接。

尤其是，require和use报表应该在文件的开头，在open tag之后。

其次，您不需要在try/catch块中实例化客户端。

这是正确的代码：

<?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; 
?>
