So I cloned the repo and worked with it with php 7.4 and php 8.2. PHP 7.4 worked flawlessly despite the repo having many bugs. PHP 8.2 did not work because it's trying to use an old method of implode() where you reverse the arguments and PHP8 straightened that out. I don't think there's a bug here. There's just a very unmaintained repo with issues.
