3. Silex
4. composer.json “require”: { “silex/silex”: “~1.3” }
5. Silex <?php chdir(dirname(__DIR__)); require ‘vendor/autoload.php’; use Silex\Application; $app = new Application(); $app->get(‘/’, function() { return new Response(‘Hello World!’, 200); }); $app->run();

8. Who Monologs • Symfony2 • Silex • Laravel 4 &5 • Lumen • PPI • XOOPS 2.6 • Aura • Proton • Plugins (CodeIgniter, Nette, Slim, …)
9. composer.json “require”: { “silex/silex”: “~1.3”, “monolog/monolog”: “~1.14” }
10. Monolog <?php use Monolog\Logger; use Monolog\Handler\StreamHandler; $log = new Logger('channel'); $log->pushHandler(new StreamHandler( 'path/to/your.log', Logger::WARNING )); $log->addWarning('Foo'); $log->addError('Bar');
11. Silex Providers
12. Silex MonologProvider <?php chdir(dirname(__DIR__)); require 'vendor/autoload.php'; use Silex\Application; $app = new Application(); $app->get('/', function() { return new Response(‘Hello World!’, 200); }); $app->run(); $app->register(new MonologProvider());
13. MonologProvider class MonologProvider implements ServiceProviderInterface { public function boot(Application $app) { ErrorHandler::Register( $app['monolog'], $error_mapping, LogLevel::ERROR, LogLevel::ERROR ); if (isset($app['monolog.listener'])) { $app['dispatcher']->addSubscriber( $app['monolog.listener'] ); } } }
14. MonologProvider public function register(Application $app) { $app['monolog'] = $app->share(function($app) { $app['monolog.listener'] = $app->share(function () use ($app) { return new LogListener($app['logger']); }); $monolog = new Logger('channel'); $monolog->pushHandler(new ErrorLogHandler()); return $monolog; }); $app['logger'] = function () use ($app) { return $app['monolog']; }; } }
15. Monolog Handlers (some) StreamHandler RotatingFileHandler SyslogHandler ErrorLogHandle
16. Monolog Handlers (some) NativeMailerHandler SwiftMailerHandler MandrillHandler
17. Monolog Handlers (some) HipChatHandler SlackHandler FleepHookHandler
18. Monolog Handlers (some) ZendMonitorHandler ChromePHPHandler BrowserConsoleHandler DB?
19. Monolog Formatters (some) LineFormatter HtmlFormatter JsonFormatter ChromePHPFormatter

21. Telegram
22. Telegram Telegram API MTProto
23. Telegram CLI https://github.com/vysheng/tg
24. Example MONOLOG \Exception
25. Telegram CLI ./bin/telegram-cli --json -dWS /tmp/tg.sck &
26. Telegram CLI PHP Bridge https://github.com/zyberspace/php-telegram-cli-client
27. composer.json “require”: { “silex/silex”: “~1.3”, “monolog/monolog”: “~1.14”, “zyberspace/telegram-cli-client”: “~0.3” }
28. Telegram Handler class TelegramHandler extends MailHandler { protected $telegram; protected $contact; }
29. Telegram Handler class TelegramHandler extends MailHandler { (…) public function __construct( Client $telegram, $contact, $level = Logger::ERROR, $bubble = true ) { parent::__construct($level, $bubble); $this->telegram = $telegram; $this->contact = $contact; } }
30. Telegram Handler class TelegramHandler extends MailHandler { protected $telegram; protected $contact; public function __construct(…) {…} protected function send($content, $records) { $this->telegram->msg( $this->contact, $content ); } }
31. MonologProvider define('TG_CONTACT', 'chat#365532'); define('TG_SOCKET', '/tmp/tg.sck');
32. MonologProvider class MonologProvider implements ServiceProviderInterface { public function register(Application $app) { (…) if (file_exists(\TG_SOCKET)) { $telegram = new Client('unix://' . \TG_SOCKET); $monolog->pushHandler(new TelegramHandler( $telegram, \TG_CONTACT )); } (…) } define('TG_CONTACT', 'chat#365532'); define('TG_SOCKET', '/tmp/tg.sck');
