Many programmers are afraid of everything new, because mastering a new technology takes time, better old, but familiar, than new, unknown and not always the best. We must always evolve and go forward. On native PHP you will not go far.
Framework - a set of ready-made functions, procedures, and much more, created in order to save the programmer from the routine work. Almost all frameworks are built using OOP principles and it was nice to understand these three letters before developing them. Using frameworks is a good step that allows you to focus on writing the business logic of your application, instead of selling bicycles.
I advise you to look towards such frameworks as Yii, Symfony, Laravel. You have chosen Laravel. Try to rewrite after writing on Laravel on Yii, Symfony. And immediately understand the difference. The main thing to know the language itself is good, but technology always changes and requires attention to itself. By the way, symfony has very good routing.
Successful coding ...
