dynamic include?

[Shile]

I am a php Noob....
I builded a site with include() functions...top, header, left menu, right menu, footer and in central tabel I have contect.php.

Thats like working with html....all pages must be done by hand and called with link www.mysite.xxx/newpage.php....

BUT I want that I can change (load) only different content2.php instead (and in the same table!!
is that possible?
and what is the code?
I want that other include files be intact and just to load different contentX.php file.

Please help.

You would have to load a new page - php can only do things at the server.
