One thing to start it's maybe the Richardson Maturity Model, that explain some basic things about the api rest model and how to make it good. Another one is to read about api rest .

The internet is full of things, only need to search something like "api rest guide", "api rest formats", "api rest response", "api rest app" or something similar to see so many information.

From PHP you have a lot of frameworks and libraries to help.

maybe look at the php slim library and oauth as a basic starting point :) as @mevrael mentioned one thing is an architecture the other thing is an implementing language :)

you could however look into different REST-API libraries written in PHP :).

There is no connection to REST, API development and any programming language like PHP.

Please use Google for such simple questions. There are a lot of links if you will type "php rest"

You can take a look on Laravel, or better on Lumen if you need to build only API: coderexample.com/restful-api-in-lumen-a-laravel-m…

Check out this series on Laracasts. Incremental API Development. @jeffreyway Does a great job of explaining things.

Ram, I've been collecting resources related to API and have a collection for the same in Hashnode.

You can check out the collection that I've created and see if that helps you.
