It seemed reasonable to me that some sort of basic structure could be established to support events in PHP 5, so I set out to whip something up as quickly as possible as a proof of concept. The contents of this article are the work of roughly one programming hour and surely stand to be improved upon, but the basic idea is this: instantiate an object and attach event handlers; the handlers will be executed when the events they are associated with are raised.
PHP has the drawback of not supporting events. Fortunately, a basic structure can be built to support events in PHP 5. This article tackles that problem with some proof of concept code.
They look first at how to create a simple object to store the information in and a "collection" class to manage those objects. They move on to the creation of the event handler class and a "collection" class for handling those as well. Finally, they get to the combination of the above items - a class that does an eval on the inputted string and creates an associative array.
