我需要一个用于PHP的XMPP库

Posted 2021-05-07

而且我不能使用作曲器（服务器在防火墙后面，php-download.com无法正常工作]

特别是，我需要导出用户列表及其组

我已经尝试过https://code.google.com/archive/p/xmpphp/，但它与PHP 7不兼容

答案

因此您不能在服务器上使用composer，但是为什么不在计算机上使用composer会加载相关性并上传供应商文件夹。然后，您便拥有了所需的一切。

Composer将所有依赖项下载到vendor文件夹，并生成一些自动加载文件。当您上传孔项目时，它应该可以工作。

这是XMPP客户端的开始。花了一段时间才找到要连接的基本代码，我注意到其他人要求这样做但没有得到它。
