Methods to override: notify($event, $msg) This implements the Observer design pattern defining the Observer class. Observer objects can be "attached" to Observable objects to listen for a specific event. Example:
$log = new Logger($logfile); //Logger extends Observer $foo = new Foo(); //Foo extends Observable $foo->attach('moo',$log); //Now $log observers 'moo' events in $foo class of $foo->attach_all($log); // Same but all events are listened
