Returning JSON from a PHP Script

Question

I want to return JSON from a PHP script.

Do I just echo the result? Do I have to set the Content-Type header?

Answer 1

A simple function to return a JSON response with the HTTP status code.

function json_response($data=null, $httpStatus=200)
{
    header_remove();

    header("Content-Type: application/json");

    http_response_code($httpStatus);

    echo json_encode($data);

    exit();
}
