php套接字的结果不一致

我面临着一个我对PHP套接字不太了解的问题；我得到了“不一致”的结果，因为通信似乎不稳定，我不知道如何设置流超时

长话短说：我试图获得一个套接字服务器，一些客户端通过VPN连接到该服务器（我知道，我的服务器现在不是多线程的…，我需要更多这方面的技能！）以获得最新的配置，为我今天关注的asterisk生成多个配置文件。服务器是一个简单的PHP套接字脚本

socket.PHP

，客户端由网关

action.PHP

组成，用于任何模块，这些模块使用各自应用程序/目录中PHP cli脚本中的类。例如，我有

modules/pbx/app/update_sip.php

，它使用

modules/pbx/classes/PbxGenerateConfig.php

通过

modules/api/classes/ApiServer.php

socket客户端从socket服务器json响应获取（并写入）配置文件。我希望大家都清楚；）

这里是一些摘录（请不要犹豫，要求更多，因为我真的不知道我错过了什么…）

我已经发展了很长一段时间，但我一个字也不懂你写的，也不知道你想完成什么，或者你认为哪里出了问题。再加上那堵代码墙，我想现在没有人能给你什么帮助了。我甚至什么都不懂…数据库：：get（'management'）…你的数据库类和get函数定义在哪里？我正试图通过PHP套接字从远程服务器获取一些配置数据（通过客户端和服务器之间的VPN建立），但这就像我只得到了json响应的一部分…不确定它是否与网络相关，但向客户端和服务器添加一些超时似乎更好（从对套接字/服务器的4个请求中获得至少2个完整结果），所以我想我现在需要在流本身上添加一些超时，因为在本地没有任何问题！问题只在我通过VPN时出现（25ms，pings似乎稳定）。@CodeLover当我调用Database:：时，这些类由include Autoload.php自动加载，get（）用于查找要查询的正确数据库。
