hide php code

Hi,

I have a webserver which some user have their own accounts on. I want
to provide the users with some public classes which they may use use
when they are making there own php code placed in their own
directories.

I want the code to be accessable via an interface (like h-files in c)
but I do not want my code to be viewable to the users which are using
my classes. Very much like a library or something.
How do I make php code which are hidden but are free to use by my
users with a defined interface against my classes?

If there's a way to do so, I can only think of a PHP encoder like Turck
MMCache or a similar tool:

http://turck-mmcache.sourceforge.net/index_old.html

Check the "Encoder" part.

try defining an additional include-path in the php.ini file. then just
tell them the class names to include. they won't be able to see the code
- i think. it's the same procedure as with the pear-packages :)

The original poster isn't concerned about regular system users seeing the
code--what she doesn't want is that webmasters can see the source code!

*Normally* the browser is on the client - and PHP files are on the server.

Your source code needs to be processable by the PHP compiler.
But, you don't want your code-users to "see" it.
This is an unsolvable problem when stated this way.

What you can do is to obfuscate the source code you want them
to use. This enables them (and the compiler) to see the public interface,
and to "see" the class bodies, but if the class bodies
are sufficiently obfuscated, it won't do them much good
to see it.

might be you can put the script in the include directory and use zend to
encode it~

It's not cheap, but it's very good.
