$app->get('/give404', function ($request, $response, $args) {
    $response->write("test");
    $newResponse = $response->withStatus(404);
    return $newResponse;
});

   public function withStatus($code, $reasonPhrase = '')

   of Response.php

   LOCALHOST

   test

   selectede code 404

   int(404)

   this is the clone clone

   object(Slim\Http\Response)#48 (5) { ["status":protected]=> int(404) ["reasonPhrase":protected]=> string(0) "" ["protocolVersion":protected]=> string(3) "1.1" ["headers":protected]=> object(Slim\Http\Headers)#43 (1) { ["data":protected]=> array(1) { ["content-type"]=> array(2) { ["value"]=> array(1) { [0]=> string(24) "text/html; charset=UTF-8" } ["originalKey"]=> string(12) "Content-Type" } } } ["body":protected]=> object(Slim\Http\Body)#53 (6) { ["stream":protected]=> resource(70) of type (stream) ["meta":protected]=> array(6) { ["wrapper_type"]=> string(3) "PHP" ["stream_type"]=> string(4) "TEMP" ["mode"]=> string(3) "w+b" ["unread_bytes"]=> int(0) ["seekable"]=> bool(true) ["uri"]=> string(10) "php://temp" } ["readable":protected]=> NULL ["writable":protected]=> bool(true) ["seekable":protected]=> NULL ["size":protected]=> NULL } }

   production environment

   test

   selectede code 404

   int(404)

   this is the clone clone

   There is a difference here :

   in App.php

   public function respond(ResponseInterface $response)

   in localhost , headers_sent() is false, on production server is true , but getStatusCode is correct (404)

   public function respond(ResponseInterface $response)
       {
           if(!headers_sent()){
               echo "!headers sent";
           } else {
               echo "headers sent";
           }
           echo "getStatusCode " . $response->getStatusCode();

   !headers sentgetStatusCode 404

   but because in production environment header is alredy there, the

   header(sprintf(
                   'HTTP/%s %s %s',
                   $response->getProtocolVersion(),
                   $response->getStatusCode(),
                   $response->getReasonPhrase()
               ));

   block will not be executed.

   i created header.php with this code

   <?php
   header("HTTP/1.0 422 TEST");
   ?>

   and ONLINE i obtain

   Status Code:422 TEST

   so the server sets header.

   but there http://php.net/manual/en/function.headers-sent.php

   i read

   "You can't add any more header lines using the header() function once the header block has already been sent. Using this function you can at least prevent getting HTTP header related error messages. Another option is to use Output Buffering."

   and here http://php.net/manual/en/function.header.php i read that header cannot be changed if everything was already sent.

   can be this the case?

   i make a try on three web hosting provider.

   www.joomlahost.it fails : return 200
   cheweb.it fails : it return 200
   http://abioneperhobby.96.lt/api/404 fails, it return 200

   this is the code, based on the new 3.1 slim

   $app->get('/404', function ($request, $response, $args) {
       $response->write("404")->withStatus(404);
   var_dump($response);
       return $response;
   });

   i was sure i had answered this issue but not.

   i solved.

   One of my .php classes ended with ?> and this make web server anwsering with some text . text explained why header was already sent.

   after removing ?> ,

   not header was alredy sent,

   and setting the new http status code worked.

   nanaksr try to remove everything and introduce one class at time
