Charcoal App is a PHP framework to create web applications and APIs using Charcoal components.

The framework is built on top of Slim 3 and Pimple.

The framework features (internally and externally) the following:

  • PSR-3 logger
  • PSR-6 cache system
  • PSR-7 kernel (web, API, CLI)
  • PSR-11 container
  • Translation layer
  • File system layer
  • Database layer
  • View layer

Service Providers

Dependencies and extensions are handled by a dependency container, using Pimple, which can be defined via service providers (Pimple\ServiceProviderInterface).

Included Providers

The Charcoal App comes with several providers out of the box. All of these are within the Charcoal\App\ServiceProvider namespace:

External Providers

The Charcoal App requires a few providers from independent components. The following use their own namespace and are automatically injected via the AppServiceProvider:

Usage

Typical Front-Controller (www/index.php):

use \Charcoal\App\App;
use \Charcoal\App\AppConfig;
use \Charcoal\App\AppContainer;

include '../vendor/autoload.php';

$config = new AppConfig();
$config->addFile(__DIR__.'/../config/config.php');
$config->set('ROOT', dirname(__DIR__) . '/');

// Create container and configure it (with charcoal-config)
$container = new AppContainer([
    'settings' => [
        'displayErrorDetails' => true
    ],
    'config' => $config
]);

// Charcoal / Slim is the main app
$app = App::instance($container);
$app->run();

For a complete project example using charcoal-app, see the charcoal-project-boilerplate.
