Documentation on securing apps is here: Securing Applications and Services Guide

What kind of application are you trying to secure? A frontend/UI application? An API server application? If you give us more information, we can point you in the right direction. There are lots of relevant examples, depending on what you’re doing.

For the PHP backend, I couldn’t find great tutorials, but these seemed to be helpful:
