PHP_Application is a platform for development of event-driven applications in which two mechanisms of distribution of events are realized. The first level are objects and their events, the second - the application and its events. The mechanism of distribution of events of the applications supports distribution of the directed and broadcasting events, and also provides synchronous or asynchronous processing events.
The structure of the application represents hierarchy of objects with various levels of abstraction. Functionality of the application is completely defined by a set of the objects included in the application, and interaction between them, i.e. a stream of events. The used application structure allows to operate a stream of events extending downwards on object hierarchy.
