我正在尝试将 neo4j 连接到 php。我正在使用 Windows 并使用 XAMPP 服务器。

我发现了一个和我类似的问题。 Neo4 给出错误：“未捕获的异常 'Everyman\Neo4j\Exception' 并带有消息 '无法检索服务器信息 [500]:”。

根据上面链接中给出的解决方案。我收到以下错误。

       Fatal error: Undefined constant 'Everyman\Neo4j\Transport\Curl' in C:\xampp\htdocs\con1.php on line 4

我尝试通过命令行运行 php neo4jphp.phar，我收到以下错误

            Fatal error: Uncaught exception 'Everyman\Neo4j\Exception' with message 'Unable to retrieve server info [500]:
            Headers: Array
            (

              thrown in phar://C:/xampp/php/neo4jphp.phar/lib/Everyman/Neo4j/Command.php on line 116

另外，当我运行以下代码时

<?php
      use Everyman\Neo4j\Client,
          Everyman\Neo4j\Transport;
      require('neo4jphp.phar');
          $client = new Client(new Transport('localhost', 7474)); 
          print_r($client->getServerInfo());
          ?>

我收到以下错误

                Fatal error: Uncaught exception 'Everyman\Neo4j\Exception' with message 'Unable to retrieve server info [500]: 
            Headers: Array ( ) Body: Array ( [error] => Failed connect to localhost:7474; No error [7] )

            #5 {main} thrown in phar://C:/xampp/htdocs/neo4jphp.phar/lib/Everyman/Neo4j/Command.php on line 116

可能是什么错误？
