Slim JSON Outputs

Question

I am using the Slim framework with PHP to create a RESTful API for my app. However, I assumed that the framework would have some way of creating easier JSON outputs rather than

Answer 1

Using Slim 3, I'm using this format:

get('/{id}', function ($request, $response, $args) {
    $id = $request->getAttribute('id');

    return $response->withJSON(
        ['id' => $id],
        200,
        JSON_UNESCAPED_UNICODE
    );
});

On request "/123", result JSON with:

{
  id: "123"
}

[UPDATE] Added second and third param to withJSON. Second is The HTTP status code, and third is Json encoding options (best for especial chars and others, for example: print "ã" correctly)
