How to compile PHP into opcode and run it in production environment?

Note,it's not what the recent hiphop project of f开发者_运维百科acebook,I just want to convert it into opcode,not c/c++.

Is there a solution yet?

A demo is always the best!

What you're looking for is a PHP Accelerator

However, these tools compile to bytecode, not opcode as requested.

@Dolph's answer is correct: There's no way to compile PHP directly to opcode. The PHP binary itself compiles PHP code to PHP bytecode and then executes those bytecodes. The best you can expect it to cache the compiled bytecode with a PHP accelerator. Other than that, the only route would be to use a langugae which does compile to opcode, which is the aim of the Facebook hiphop project.
