How to get opcodes of PHP?

As I dig deeper into developing in a specific language, at some point, if possible, I like to view the opcode of the language to give me a deeper understanding of how my code is interpreted or compiled. C/C++ you can usually switch to disassembly view in an IDE, or have the compiler output its instructions. Flash, you can use a utility like flasm to see what's going on..

Is there an option to view PHP's opcode? I took a look through php command line parameters, but didn't see anything (maybe I just missed it?).
