How to merge a raw php project with a laravel project?

Actually I am working on a project who's sub-part is developed using Laravel 5. But The Sub-Part I am working is a raw php project . Now I want to run this to proejct as a single one . As I have not much time I can not convert Laravel-> rawPhp or raw Php -> Laravel . Database tables for this to subpart don't overlap .

Now what is the best feasible solution for my project ?
