Get headers from Symfony\Component\HttpFoundation\Response - php

Question

For debugging purposes I want to log all headers from the response object like so in filters.php:
App::after(function($request, $response) {
if(App::environment() !== 'dev') { return; }
error_log(print_r($response->getHeadersPleaaase()));
$response is typically a Illuminate\Http\JsonResponse and I cannot find any obvious method for getting the headers there.

Answer 1

Headers is a public property:
error_log(print_r($response->headers));

Answer 2

ini_set("log_errors", 1);
ini_set("error_log", __DIR__.'/../app/logs/prod.log');//ini_set("error_log", your path and file);
error_log( 'BEGIN===========>' );
error_log( $request );
error_log( $response );
error_log( '<========END' );
an example of using (Symfony2)
app.php
<?php
use Symfony\Component\ClassLoader\ApcClassLoader;
use Symfony\Component\HttpFoundation\Request;
$loader = require_once __DIR__.'/../app/bootstrap.php.cache';
// Use APC for autoloading to improve performance.
// Change 'sf2' to a unique prefix in order to prevent cache key conflicts
// with other applications also using APC.
/*
$apcLoader = new ApcClassLoader('sf2', $loader);
$loader->unregister();
$apcLoader->register(true);
*/
require_once __DIR__.'/../app/AppKernel.php';
//require_once __DIR__.'/../app/AppCache.php';
$kernel = new AppKernel('prod', false);
$kernel->loadClassCache();
//$kernel = new AppCache($kernel);
// When using the HttpCache, you need to call the method in your front controller instead of relying on the configuration parameter
//Request::enableHttpMethodParameterOverride();
$request = Request::createFromGlobals();
$response = $kernel->handle($request);
ini_set("log_errors", 1);
ini_set("error_log", __DIR__.'/../app/logs/prod.log');
error_log( 'BEGIN===========>' );
error_log( $request );
error_log( $response );
error_log( '<========END' );
$response->send();
$kernel->terminate($request, $response);
