There is example of using Monolog with PHP-DI (from manual, there are 2 files - index.php and config.php:
<?php
// config.php
use Monolog\Logger;
use Monolog\Handler\StreamHandler;
return [
// ...
Psr\Log\LoggerInterface::class => DI\factory(function () {
$logger = new Logger('mylog');
$fileHandler = new StreamHandler('path/to/your.log', Logger::DEBUG);
$fileHandler->setFormatter(new LineFormatter());
$logger->pushHandler($fileHandler);
return $logger;
}),
];
This config.php is using in the below code:
// index.php
use DI\ContainerBuilder;
require __DIR__ . '/../vendor/autoload.php';
$containerBuilder = new ContainerBuilder;
$containerBuilder->addDefinitions(__DIR__ . '/config.php');
$container = $containerBuilder->build();
How could I use it now in index.php? Regularly I use Monolog this way:
$log = new Logger('name');
$log->warning('Foo');
But how to call it with Container?
I was able to do it in simple $container->set(), $container->get() mode. But in this way using Container Builder I can't find a way to do it. Moreover when I make var_dump($container) there are no any logger's signs in it.
You need to replace $log = new Logger('name') with:
$log = $container->get(\Psr\Log\LoggerInterface::class);
See this part of the documentation: http://php-di.org/doc/getting-started.html#3-create-the-objects

I am trying to learn slim framework and I am following the tutorial. What I would like is a detailed explanation of what the be low snippet of code is doing within the slim environment.
$app->get('/client/{name}'
The reason that I am asking is because in keep getting route not found. But I have yet to figure out why. The base route works. But when I added the twig and tried to route to that. It fails.
Now comes the code:
This part is in my webroot/public/index.php
<?php
use DI\Container;
use Slim\Factory\AppFactory;
use Slim\Views\Twig;
use Slim\Views\TwigMiddleware;
use Twig\Error\LoaderError;
require __DIR__ . '/../vendor/autoload.php';
$container = new Container;
$settings = require __DIR__ . '/../app/settings.php';
$settings($container);
AppFactory::setContainer($container);
$app = AppFactory::create();
$app->addRoutingMiddleware();
$app->addErrorMiddleware(true, true, true);
// Create Twig
$twigPath = __DIR__ . "/../templates";
$twig = '';
try {
$twig = Twig::create($twigPath, ['cache' => false]);
} catch (LoaderError $e) {
echo "Error " . $e->getMessage();
}
// Add Twig-View Middleware
$app->add(TwigMiddleware::create($app, $twig));
$routes = require __DIR__ . '/../app/routes.php';
$routes($app);
$app->run();
This part is in the routes.php:
<?php
use Slim\App;
use Psr\Http\Message\ResponseInterface as Response;
use Psr\Http\Message\ServerRequestInterface as Request;
use Slim\Views\Twig;
return function (App $app) {
$app->get('/', function (Request $request, Response $response, array $args) {
$response->getBody()->write("Hello world! Really?");
return $response;
});
$app->get('/client/{name}', function (Request $request, Response $response, $args) {
$view = Twig::fromRequest($request);
return $view->render($response, 'client_profiles.html', [
'name' => $args['name']
]);
})->setName('profile');
};
The first route works fine the second does not. According to what I am reading. It should work. https://www.slimframework.com/docs/v4/features/templates.html
I feel that if I knew what get is looking to do. I may be able to fix it and build a proper route.
When I dig into the $app->get which connects with the RouterCollecorProxy.php. There is the $pattern variable and $callable. The callable is the anonymous function that comes after the common in the
$app->get('/client/{name}', function <- this is the callable, right?
I see the map class which takes me to the createRoute which returns the $methods, $pattern, callable and a few other things.
I think the pattern is where my problem is.
I have just created slim 4 project using "composer create-project slim\slim-skeleton appdb". I have a routes.php as
<?php
declare(strict_types=1);
use App\Application\Actions\User\ListUsersAction;
use App\Application\Actions\User\ViewUserAction;
use Psr\Http\Message\ResponseInterface as Response;
use Psr\Http\Message\ServerRequestInterface as Request;
use Slim\App;
use Slim\Interfaces\RouteCollectorProxyInterface as Group;
return function (App $app) {
$app->post('/hello', function (Request $request, Response $response) {
$response->getBody()->write('Hello world!');
return $response;
});
};
and the index.php as
<?php
declare(strict_types=1);
use App\Application\Handlers\HttpErrorHandler;
use App\Application\Handlers\ShutdownHandler;
use App\Application\ResponseEmitter\ResponseEmitter;
use DI\ContainerBuilder;
use Slim\Factory\AppFactory;
use Slim\Factory\ServerRequestCreatorFactory;
require __DIR__ . '/../vendor/autoload.php';
// Instantiate PHP-DI ContainerBuilder
$containerBuilder = new ContainerBuilder();
if (false) { // Should be set to true in production
$containerBuilder->enableCompilation(__DIR__ . '/../var/cache');
}
// Set up settings
$settings = require __DIR__ . '/../app/settings.php';
$settings($containerBuilder);
// Set up dependencies
$dependencies = require __DIR__ . '/../app/dependencies.php';
$dependencies($containerBuilder);
// Set up repositories
$repositories = require __DIR__ . '/../app/repositories.php';
$repositories($containerBuilder);
// Build PHP-DI Container instance
$container = $containerBuilder->build();
// Instantiate the app
AppFactory::setContainer($container);
$app = AppFactory::create();
$callableResolver = $app->getCallableResolver();
// Register middleware
$middleware = require __DIR__ . '/../app/middleware.php';
$middleware($app);
// Register routes
$routes = require __DIR__ . '/../app/routes.php';
$routes($app);
/** #var bool $displayErrorDetails */
$displayErrorDetails = $container->get('settings')['displayErrorDetails'];
// Create Request object from globals
$serverRequestCreator = ServerRequestCreatorFactory::create();
$request = $serverRequestCreator->createServerRequestFromGlobals();
// Create Error Handler
$responseFactory = $app->getResponseFactory();
$errorHandler = new HttpErrorHandler($callableResolver, $responseFactory);
// Create Shutdown Handler
$shutdownHandler = new ShutdownHandler($request, $errorHandler, $displayErrorDetails);
register_shutdown_function($shutdownHandler);
// Add Routing Middleware
$app->addRoutingMiddleware();
// Add Error Middleware
$errorMiddleware = $app->addErrorMiddleware($displayErrorDetails, false, false);
$errorMiddleware->setDefaultErrorHandler($errorHandler);
// Run App & Emit Response
$response = $app->handle($request);
$responseEmitter = new ResponseEmitter();
$responseEmitter->emit($response);
Attempts to access post route as 127.0.0.1/appdb/public/hello/Peter, gives an error
{ "statusCode": 404, "error": { "type": "RESOURCE_NOT_FOUND", "description": "Not found." } }
What am I doing wrong?
Thanks in advance
I have this plain console program:
namespace MyApp\Console;
use Symfony\Component\Console\Command\Command;
use Symfony\Component\Console\Input\InputArgument;
class MaConsole extends Command {
protected function configure()
{
$this->setDescription('Console\'s not console');
}
protected function execute(
\Symfony\Component\Console\Input\InputInterface $input,
\Symfony\Component\Console\Output\OutputInterface $output
) {
$output->writeln('Doing Stuff');
}
}
And I load it like that:
namespace MyApp;
use Symfony\Component\Console\Application as SymfonyApplication;
use MyApp\Console\MaConsole;
class Application extends SymfonyApplication
{
public function __construct(
string $name = 'staff',
string $version = '0.0.1'
) {
parent::__construct($name, $version);
throw new \Exception('Test Sentry on Playground');
$this->add(new MaConsole());
}
}
And I want to log the exception thrown above in Sentry service. So I my entrypoint is:
use MyApp\Application;
require __DIR__ . '/vendor/autoload.php';
Sentry\init([
'dsn' => getenv('SENTRY_DSN'),
'environment' => getenv('ENVIRONMENT')
]);
$application = (new Application())->run();
But I fail to log the error into sentry, even thouhg I have set the correct enviromental variables.
The application does not load the Full Symfony framework, but instead it uses the console only components so I have no idea if I should use the Sentry Symfony Integration: https://docs.sentry.io/platforms/php/symfony/
The reason why is because I do not know how in my case to load the bundle, therefore I use the SDK.
Edit 1:
I also tried to catch the exception and manually log it but form some reason is not logged as well:
use MyApp\Application;
require __DIR__ . '/vendor/autoload.php';
try {
Sentry\init([
'dsn' => getenv('SENTRY_DSN'),
'environment' => getenv('ENVIRONMENT')
]);
throw new \Exception('Test Sentry on Playground');
$application = (new Application())->run();
} catch(Exception $e) {
Sentry\captureException($e);
}
You can use the dispatcher :
use Symfony\Component\EventDispatcher\EventDispatcher;
$dispatcher = new EventDispatcher();
$dispatcher->addListener(ConsoleEvents::ERROR, function (ConsoleErrorEvent $event) use ($env) {
Sentry\init([
'dsn' => getenv('SENTRY_DSN'),
'environment' => $env
]);
Sentry\captureException($event->getError());
});
$kernel = new AppKernel($env, $debug);
$application = new Application($kernel);
$application->setDispatcher($dispatcher);
$application->run($input);
I'm trying to add twig-view in slim v4
In slim v3, we add twig-view in container
$container['view'] = function ($c) {
$view = new \Slim\Views\Twig('path/to/templates', [
'cache' => 'path/to/cache'
]);
// Instantiate and add Slim specific extension
$router = $c->get('router');
$uri = \Slim\Http\Uri::createFromEnvironment(new \Slim\Http\Environment($_SERVER));
$view->addExtension(new \Slim\Views\TwigExtension($router, $uri));
return $view;
};
but I can't add twig like that in slim v4
Update: Twig-View has reached a stable version and the docs are updated to address Slim 4 integration.
If you are still using an unstable version of Twig-View, please consider upgrading.
First, you need to add Twig-View package to your project:
composer require slim/twig-view
And assuming the following directory structure:
composer.json
cache/
public/
|--index.php
templates/
|--hello.twig
vendor/
|--autoload.php
The followings are two working examples:
If you use a container (which is optional according to Slim 4 docs), you can add Tiwg creation definition to the container and use it when required. (I'm using php-di/php-di in this example, but you can use any PSR compatible dependency container.)
index.php, using a container:
<?php
use DI\Container;
use Slim\Factory\AppFactory;
use Slim\Views\Twig;
use Slim\Views\TwigMiddleware;
require __DIR__ . '/../vendor/autoload.php';
// Create Container
$container = new Container();
AppFactory::setContainer($container);
// Set view in Container
$container->set('view', function() {
return Twig::create(__DIR__ . '/../templates',
['cache' => __DIR__ . '/../cache']);
});
// Create App
$app = AppFactory::create();
// Add Twig-View Middleware
$app->add(TwigMiddleware::createFromContainer($app));
// Example route
$app->get('/hello/{name}', function ($request, $response, $args) {
return $this->get('view')->render($response, 'hello.twig', [
'name' => $args['name']
]);
});
// Run the app
$app->run();
You can also skip the container creation, but in that case you need to create the Twig instance before trying to render a template.
index.php, without a container:
<?php
use Slim\Factory\AppFactory;
use Slim\Views\Twig;
use Slim\Views\TwigMiddleware;
require __DIR__ . '/../vendor/autoload.php';
// Create App
$app = AppFactory::create();
// Create Twig
$twig = Twig::create(__DIR__ . '/../templates',
['cache' => __DIR__ . '/../cache']);
// Add Twig-View Middleware
$app->add(TwigMiddleware::create($app, $twig));
// Example route
// Please note how $view is created from the request
$app->get('/hello/{name}', function ($request, $response, $args) {
$view = Twig::fromRequest($request);
return $view->render($response, 'hello.twig', [
'name' => $args['name']
]);
});
// Run the app
$app->run();
hello.twig:
Hello {{ name }}
Now try visiting /hello/slim4 in your browser and the output will be:
Hello slim4
SlimTwigView is at 3.0.0 beta (at least as of October 12, 2019), and some things have changed. The few online tutorials I've seen, as well as the official documentation no longer work.
TwigMiddleware no longer takes an instance of the $container as an argument, so you must first put Twig on the Container manually such as:
$container->set('view', function() {
// Of course put correct path to your views here
return new Twig('../views', ['cache' => false]);
});
You then you can add TwigMiddleware to your Slim App using the class' new createFromContainer method, like so:
$app->add(TwigMiddleware::createFromContainer($app));
// which is equivalent to:
// $app->add(TwigMiddleware::createFromContainer($app, 'view'));
At that point, you can render a Twig view like so:
$app->get('/', function (Request $request, Response $response, $args) {
return $this->get('view')->render($response, 'home.twig');
});
When using the Slim specific middleware, you now have access to the additional Twig extensions:
url_for
full_url_for
is_current_url
current_url
get_uri
Well! In my case I was using Slim 4.0 and Twig ^2.5. All I added to my code was
$container->set('view', function () use ($container) {
$view = new \Slim\Views\Twig(
__DIR__ .'/Templates'
, [ 'cache' => false ] //you can turn on caching by providing string path to cache or set to false
);
return $view;
});
I'm writing my own PHP framework built on top of Symfony components as a learning exercise. I followed the tutorial found at http://symfony.com/doc/current/create_framework/index.html to create my framework.
I'd now like to wire up my routes against my controllers using annotations. I currently have the following code to setup the routing:
// Create the route collection
$routes = new RouteCollection();
$routes->add('home', new Route('/{slug}', [
'slug' => '',
'_controller' => 'Controllers\HomeController::index',
]));
// Create a context using the current request
$context = new RequestContext();
$context->fromRequest($request);
// Create the url matcher
$matcher = new UrlMatcher($routes, $context);
// Try to get a matching route for the request
$request->attributes->add($matcher->match($request->getPathInfo()));
I have come across the following class to load the annotations but I'm not sure how to use it:
https://github.com/symfony/symfony/blob/master/src/Symfony/Component/Routing/Loader/AnnotationDirectoryLoader.php
I'd appreciate it if someone could help.
Thanks
I've finally managed to get this working. First I changed where I included the autoload.php file to the following:
use Doctrine\Common\Annotations\AnnotationRegistry;
$loader = require __DIR__ . '/../vendor/autoload.php';
AnnotationRegistry::registerLoader([$loader, 'loadClass']);
Then I changed the routes collection bit (in the question) to:
$reader = new AnnotationReader();
$locator = new FileLocator();
$annotationLoader = new AnnotatedRouteControllerLoader($reader);
$loader = new AnnotationDirectoryLoader($locator, $annotationLoader);
$routes = $loader->load(__DIR__ . '/../Controllers'); // Path to the app's controllers
Here's the code for the AnnotatedRouteControllerLoader:
class AnnotatedRouteControllerLoader extends AnnotationClassLoader {
protected function configureRoute(Route $route, ReflectionClass $class, ReflectionMethod $method, $annot) {
$route->setDefault('_controller', $class->getName() . '::' . $method->getName());
}
}
This has been taken from https://github.com/sensiolabs/SensioFrameworkExtraBundle/blob/master/Routing/AnnotatedRouteControllerLoader.php. You may wish to modify it to support additional annotations.
I hope this helps.
