I need an XMPP library for PHP - php

Question

And I can't use composer (the server is behind a firewall, and PHP-download.com does not work)
In particular, I need to export the user list with their groups
I have tried https://code.google.com/archive/p/xmpphp/ but it is not compatible with PHP 7

Answer 1

So you can't use composer on the server OK but why you don't use composer on your machine load the dependencies and upload the vendor folder. Then you have all you need.
Composer download all dependencies to the vendor folder and generate some autoloading files. When you upload the hole project it should work.

This is the start of an XMPP client. It took a while to find the base code to connect, and I noticed other people asking for this but not getting it.
