You compile your PHP source to a "bytecode" binary and save it to a disk. Then you run your binary (from the local machine or remotely through a Web browser) with a bytecode execution engine. This would be *exactly* like how Java works. Of course, I could be mistaken. Please correct me if I'm wrong.
