Yes, I understand that webservers can parse the php code. However, I do have major concern about security. Anyone who read my php code will know exactly what's going on. That's why I want to have it compiled into binary to make the hacker's life slightly more difficult.
Another question is that, if I can not compile the php code into binary, can I use php to work with some other language, such as Java??
Thanks for all who reply.
