Return a JSON Response with Slim

Slim can use withJson() that can return JSON responses with desired route and method

$app = new \Slim\App();
$app->get('/api/person', function ($request, $response, $args) {

$payload=[];
array_push($payload, array("name"=>"Bob"  ,"birth-year"=>1993));
array_push($payload, array("name"=>"Alice","birth-year"=>1995));

 return $response->withJson($payload,200);

});

$app->run();

Try it with curl

`curl -X GET https://127.0.0.1/api/person`

it can return an array in json

[{"name":"Bob","birth-year":1993},{"name":"Alice","birth-year":1995}]

POST Request With Slim 3 (REST API)

use \Psr\Http\Message\ServerRequestInterface as Request;
use \Psr\Http\Message\ResponseInterface as Response;

$app = new \Slim\App;

$app->post('/post/data', function (Request $request, Response $response, $arg){

    $_input = $request->getParsedBody();

    $_data_1 = $_input['name'];
    $_data_2 = $_input['email'];
    $rsp = array();

    if(!empty($_data_1 && !empty($_data_2))){

        $rsp["error"] = false;
        $rsp['message'] = "hello my name is ".$_data_1." and my email is ".$_data_2;
    }else{

        $rsp["error"] = false;
        $rsp['message'] = "you have not posted any data" ;
    }

    return $response
        ->withStatus(201)
        ->withJson($rsp);
});

$app->run();
