protecting source code

[Anon]

I am on a project and the issue that struck me is how to protect my source
codes which is in human readable form. There isn't any way for me to
protect my database and the only way that I had found out is to use the PHP
encoder provided by Zend.com to encode the source code. However, the
price of a commercial license for each machine (since it use host ID or
hostname as the key) is too costy and I am trying to find an alternative or
a cheaper packages available. I am exploring on APC as well but it seems like it doesn't encode the source code, it only encode it to be in binary format and stored in the cache memory. Please help.

There isn't any way to read your source unless someone has telnet, ssh or ftp access to your server. Even a spider program like wget will just get pure html back.

Now if you are on a shared server then I can see your issues, but I don't know any way to do what you want except for Zend's encoder.
