An interface to report and relay arbitrary messages to registered handlers. This was part of the Semantic MediaWiki code base and is now being deployed as independent library.


PHP 5.5 / HHVM 3.3 or later


The recommended installation method for this library is to add it as dependency to your composer.json.

	"require": {
		"onoi/message-reporter": "~1.3"


The message reporter specifies MessageReporter and MessageReporterAware as an interface for all interactions with a set of supporting classes:

  • MessageReporterFactory
  • ObservableMessageReporter
  • NullMessageReporter
  • SpyMessageReporter
use Onoi\MessageReporter\MessageReporterFactory;
use Onoi\MessageReporter\MessageReporterAware;
use Onoi\MessageReporter\MessageReporterAwareTrait;
use Onoi\MessageReporter\MessageReporter;

class Bar implements MessageReporterAware {

	use MessageReporterAwareTrait;

	public function __construct() {
		$this->messageReporter = MessageReporterFactory::getInstance()->newNullMessageReporter();

	public function doSomething() {
		$this->messageReporter->reportMessage( 'Doing ...' );
use Onoi\MessageReporter\MessageReporterFactory;
use Onoi\MessageReporter\MessageReporter;

class Foo implements MessageReporter {

	public function reportMessage( $message ) {
		// output

$foo = new Foo();

$messageReporterFactory = new MessageReporterFactory();

$observableMessageReporter = $messageReporterFactory->newObservableMessageReporter();
$observableMessageReporter->registerReporterCallback( array( $foo, 'reportMessage' ) );


// If the class implements the MessageReporter
$observableMessageReporter->registerMessageReporter( $foo );

$bar = new Bar();
$bar->setMessageReporter( $observableMessageReporter );
