Actually afaik PHP means Programmable Hypertext Preprocessor.
And no, although you could use java to disable right click and popups to disable menus, there are still plenty of ways to make html source available like opening urls in textpad or using non-java enabled browsers etc.
If you are worried about people ripping your PHP code, it can't be done, the only thing viisible to the end user is the outputted (is that a word lol) html.
