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

function _die($array){
   echo json_encode($array);
   exit;
}


$result = mysql_query("SELECT * FROM table");
while($row = mysql_fetch_assoc($result)){
    $array[] = $row;
}

_die($array);

Answer 2

header("Content-Type : application/json"); echo json_encode($data);

Answer 3

header("Content-Type: application/json");
echo json_encode($result);
exit;

Answer 4

Using Slim 3, I'm using this format:

<?php

$app = new \Slim\App();

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

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

On request "/123", result JSON with:

{
  id: "123"
}

More infos read here.

[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)

Answer 5

I think Slim also provides a middleware object which does this automatically so users of that framework doesnt have to write json_decode and encode on every request, its called the Slim_Middleware_ContentType object.

$app->response()->('application/json');
$app->add(new Slim_Middleware_ContentType());

it does the decoding for you. the decoding works great.But for encoding the last post is great.

Answer 6

My fix was adding "exit;" at the end of the json print out, my dev server didn't care, but my live server would not trigger the json end event. I did not need to add headers or use json_encode.
