PHP套接字不一致的结果

Question

我面临的一个问题是我对PHP套接字不太了解。 由于通讯似乎不稳定并且无法确定流超时的设置，因此我得到“不一致”结果。

长话短说：我试图获得一些客户端通过VPN连接到的套接字服务器（我知道，我的服务器目前还不是多线程的，我将需要更多技巧！）以获取最新的配置。今天我关心的是为星号生成多个配置文件。 服务器是一个简单的PHP套接字脚本socket.php ，客户端包括任何模块的网关action.php ，这些模块使用其各自app /目录中php-cli脚本中的类。 因此，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从套接字服务器json响应中获取（并写入）配置文件modules/api/classes/ApiServer.php套接字客户端。 我希望每个人都清楚;）

这是一些摘录（请不要犹豫，问更多，因为我真的不知道我在想什么...）
