How to access session of a php application via another laravel application which hosted in same domain?

I have a php application[Non Laravel] hosted on 'domain.loc' and I need to access the session data of that to login to another application which is developed using Laravel and hosted in same domain, its address is 'domain.loc/testing'.

domain.loc -- [Non Laravel App]

domain.loc/testing -- [Laravel App]

Is there any possible way to access a session of non-laravel application in a laravel application without using token-based authentication.

Or is there anyway where we can authenticate a laravel application via a non-laravel application ?
