Also, i know php is an interpreted language. But wouldn't it be possible to
write a virtual machine for php and compile byte code... I know, php is not
Java or Actionscript :-P but it could be an add on feature. i guess the eval
wouldn't work then would it? Although eval could still be interpreted...
This would be nice in case you need to protect your intellectual property.
I haven't tried it, but I might soon for an appliance I'm building.

Actually might not have "virtual machine" as java does but it has an engine and it is possible to produce something similar to byte-code. You can some solutions to this and here is one of them (open source):

and there is a script to make "byte-code":

I have used and it works.
