use Struzik\ErrorHandler\Processor\LoggerProcessor;
use Struzik\ErrorHandler\Processor\IntoExceptionProcessor;
use Struzik\ErrorHandler\Exception\ErrorException;
use Monolog\Logger;
use Monolog\Handler\StreamHandler;

$logger = new Logger('ErrorHandler DEMO');
$logger->pushHandler(new StreamHandler('php://output', Logger::DEBUG));

$errorHandler = new ErrorHandler();
$errorHandler->pushProcessor(new IntoExceptionProcessor())
    ->pushProcessor(new LoggerProcessor($logger));

try {
    $errorHandler->set();
    trigger_error('Dummy error', E_USER_NOTICE);
    $errorHandler->restore();
