Open Source PHP API Framework: FRAPI
Once we build a web application, creating an API for it and enabling anyone to interact with the service easily is a great way to help the application grow.
However, it can be a time-consuming process to build the API from scratch (if you want to build one, check: How To Create An API? -10 Tutorials-).
And this is where FRAPI, an open source PHP API framework for building an API for any web application very quickly, comes in.
The framework is RESTful, simple and only focuses on building the API. It generates the skeleton for you to handle REST calls and you only need to put your business logic in it.
From a web-based interface, it enables you to create the methods, error codes and messages for your API.
Once finished, the PHP files for the methods are created automatically where you can easily add any extra functions.
FRAPI also auto-generates the documentation for the API using the "description" fields of each function.
