Yes, php Pages are always server-side stored. Also: they include passwords, but the client-browsers cannot read the php, they can only execute it, where their browser acts as Output, like the Screen with "Print".
As I said before, the easiest way, that let's you develop php very quickly, is to install php and MySQL on your local machine. If your Script once works you can upload it to a server that supports PHP and MySQL as well. I mean, installing these Things is only easy, when you use the Package I mentioned. To install the 3 Components (apache, php, mysql) manually is a bit harder.
