4,707 PointsUsing React how do I fetch data from my PHP backend with the fetch API?
I am building my frontend with reac.js while trying to pull data from my database. The server-side language I am using is PHP. The problem is that I can't seem to retrieve data from a .php file using the fetch API. How do I make that connection from frontend to backend?

I suspect that in your PHP script(s), that you may want to return your answers as JSON.
PS, I think Jamie meant "expose an API", as in, you have a standard way to ask the server for data and a standard way for the server to return your data to the calling client.

Courses Plus Student 21,100 PointsYou can use plain old fetch API or axios. You just need to expose and API on the backend that so you can consume it on the Front.
If you are just using react, you can do it on life-cycle methods like componentWillMount or on any other component's method.
If you are using redux for state management, you can check redux-saga.

4,707 PointsI'm not familiar with "expose and API". Right now I have my .php file sitting in the public folder with index.html. When I fetch for that file I don't get a response. Do I have to hold my .php file on another server?

Here is a repository with fetch examples.
