Event Handling Classes in PHP
Been looking at what Java and .NET do in regard to event handling in web applications.
To date, most PHP apps which get into OO use a fusebox like approach, in that one script (usually index.php) is used to handle events - all things begin with index.php. That's fine but I'm wondering if there's a more generic way to do it - a class you can simple instantiate from anywhere to handle events?
Some resources for Java and .NET that discuss this;
The way I see it in PHP is something like this;
An EventRegister class (using a Singleton pattern) which any object can use to register events with.
An EventHandler class, which checks $_GET, $_POST, $_COOKIE and $_FILE for events registered with the EventRegister class.
The next (tough) question is how the EventHandler can fire off the event itself (e.g. an object which validates incoming $_POST data then another object which INSERTs into a database).
Any ideas? My attempts at writing the classes so far have left me deeply confused.
