Alan Knowles (http://pear.php.net/user/alan_k) has commented on the proposal for RFC::NotificationCenter. Comment: My original thoughts where that emulating gobjects signal model may be an idea. eg. signal::connect($obj,'signame',$callback,$args...); signal::register('class','signame'); signal::emit($obj, 'eventname',$args); But the more I look at it, something that follows W3C events API may be more familar. Event::register('classname','event'); Event::addListener($obj, 'event', $callback, $args); Event::removeListener($obj, 'event',$callback); Event::emit($obj|classname, 'event',$args); you could then wrap these in your own class: function addEventLister('event',$callback,$args) { Event::addListener($this, 'event', $callback, $args); } Without resorting to a yourclass extends Event, however it's a little complex implement object instance listeners using a vistor pattern (as it's difficult to get object instance ID's from the registered instance AFAIR) Ideally all this would be done by PHP internals (using an Event Interface) - in a similar way to Iterators..
