At work I need to make a website that allows us to display data (like certain things sold and some other statistics) and It needs to be updated easily.

Now my manager told me to let me know what I need and he'll see about getting it done but I'd rather do it with as little server-side scripting as possible.

So I need to make a site with statistics and such and it needs to be able to be modified inside of a web browser. It also needs to be platform-independant so no ActiveX controls.

Do I absolutely need a server-side technology like PHP? Would the easiest route be using PHP and saving to a text file? I take it there isn't anyway to modify a text file on a web server without some sort of server-side technology, correct?

Also, does anyone know if PHP is installed by default on OS X's apache install or not?
