You need to sit down with paper and pencil, or use some kind of charting software perhaps, and decide what "parts" your news site should have, how they will interact with each other; what each "part" will do, how it will interact with the user, and so on. Write this all in plain English (or whatever your primary language is) and then try and figure out how to accomplish this in code (PHP, I assume).
This is called the "design process" and it won't do you much good to come here and ask questions until you have some idea what you want your site to do.
i dont understand i want to make it into class
Beg pardon? Not sure what you're saying here. Don't worry about "classes" just yet ... first worry about designing your application/site. Turning that into code (functions, or classes, or objects, or methods, etc.) can come later....
