I'm developing a CMS for my university. With this Cms university staff can login and design their personal web sites without any knowledge of html or php.
What i want is separate all external applications from my CMS. For example, there is a Polls application, Gallery and Images application and so on. And others programmers will work on this.
I have to write a application platform and all other programmers will use the platform's rules and write their modules (applications).
Please offer me some solutions. I know there is nothing about the code yet. I have to think about the design pattern.
EDIT: ok, forget about the word "CMS" put "Program" instead of it. "I'm writing a PHP program which must have the ability to extend with other applications".
