As I am beginner, I am facing some issues.
I have an web application which is built in core PHP without any frameworks. Now I have developed Mobile for that web application in Ionic3 and Latest version of Angular.
I am done with all my design part of the Mobile app. I am not getting how to send and retrieve the data from the existing Database of the Web application.
I searched in google, I found PHP Restful API topic. But I am not getting how to start with it.
Also is it necessary that the web application should be developed in frameworks to create Restful API ?
Can anyone suggest me how to establish the communication between Ionic3 App and create a Restful API.
