encoding php scripts and HTML code

[zybler]

I'm developing a school management program mainly for the teachers to enter examination marks (in PHP) and i wanted to know if there was a way to encode the PHP script to pevent the code being modify or accessed by the students.

And if possible, probably hide the HTML code or make it less accessible or less likely to be modify.

Another thing, can I use proprietary windows program to hide or password-protect certain folders (that contain the database or php scripts) so that it can't be seen or opened directly on the server itself? is that a good way? is there a better way?

I'd suggest you get the school to devote a computer which isn't on the network to the site. Then you can just let Apache do the rest ;)

The school network admin should know how to deny access to certain directories, no?
