您能否告诉我哪个命令行可以帮助我重新初始化 neo4j 查询，解释更多，我有一个查询提供所有用户节点，第二个查询提供文件夹节点，不幸的是，第二个查询记住第一个查询的结果.

我有 2 个用户和 2 个文件夹。 $result1应该返回用户并$result2返回文件夹。当我查找文件夹的大小时，我得到 4 而不是 2，因此查询始终记住第一个查询的结果。

var_dump($result1)，我得到：

object(Neoxygen\NeoClient\Formatter\Result)  protected 'nodes' => 
array (size=2)
  7 => 
    object(Neoxygen\NeoClient\Formatter\Node)[796]
      protected 'id' => string '7' (length=1)
      protected 'labels' => 
        array (size=1)

这真的很奇怪，我创建了一个集成测试，证明结果在后续查询中不会重复：

https://github.com/neoxygen/neo4j-neoclient/blob/master/tests/Neoxygen/NeoClient/Tests/Issues/IssueSOResultDuplicationTest.php

所以我会看不同的立场：

  1. 确保只有 2 个文件夹节点
  2. 检查所有变量是否已重新初始化
  3. 查询中提供的标签

注意：您可以编辑原始问题，而不是创建多个回复。

我已经测试了你的代码，只是用我的数据库中的标签替换了标签，我只得到了 2 个文件夹：

在此处输入图像描述

所以我会检查数据库内容，您可以尝试在浏览器中手动进行第二个查询。
