PHP_Application is a platform for the development of event-driven applications in which two mechanisms of distribution of events for two levels of abstraction accordingly 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 a 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 structure of the application allows you to operate a stream of events extending downwards on hierarchy of objects.
FreeSMS (Free Student Management System) is a Web application for managing an educational facility. It manages teachers and students and provides marketing, registration, course management, attendance, and a student evaluation system, and manages courses within a class environment. Profile-based management is supported for administrators, teachers, and students. Teachers and students can be registered online. Students are allowed to manage their own class enrolment and submit course evaluations, and teachers can manage student attendance. The differential factor and elegance of this project lie in the OOP standard and a modular structure. The code is clean and very extendable.
