PHP session name and JSON Web Token

Both are designed to implement single sign-on,
Setting the same PHP session name allows sharing sessions between PHPRunner projects located on the same web server.
JSON Web Tokens are designed to share sessions and login between any kind of applications located on any server and not necessarily written in PHP or created by PHPRunner.

Thanks.
Is there some kind of tutorial on how to build several PHPrunner solutions in a modular way?
Would each PHPrunner file need the same users-table? Would I have to synchronize these programmatically myself?
Could I avoid uploading all the same stuff of classes for the modules?
