Obtaining Copyrights

[robot180]

I see that a lot of people, not just teams, but websites in general, say that the website is copyrighted but all they did was put the words copyright blah blah blah at the bottom of each page. As I understand, in order to have your website legally copyrighted, you have to send in copies of all of your source code and copies of every page. Does anyone know of anything else that you have to do? Also, is there an exact format for the copyright?

Our website, not up yet, is made in php and each page loads into a template. Therefore, it ends up that the same page is loaded in every time, just with a different file included into one part of the page. Does each files count as a seperate page or does the template count as THE page? What about pages and files generated by php files? For example, a page listing all of the photo galleries where all it does is read in a list from a file and display it on the screen, in the template. Does that count as a page, even though it doesn't have any source code of its own?

If anyone knows some information about copyrights, please let me know. Thanks.
