How to retrieve the OpCode?

Hi,

How could I retrieve the OpCode that PHP Engine generated for a script?

PHP is interpreted, so you're going to have a heck of a time getting this.
You can get the source from the php website though, its through the QA but I can't remember what their link is off heart (at work, no bookmarks).
Anyway, you can use that to determine what C instructions are used when PHP commands are issued. You can probably run that though a debugger and step though to the assembly to see what opcode is in use.
Have fun, this will be the most painful task ever.

I know.

I'm already working on it..

I forgot to ask, why would you need to know the opcode used for a specific script? I don't see any reason to handle this - there is a reason why we have high level programming languages nowadays.

I need to analyze PHP code and I figured it would be easier to analyze the OpCode instead of PHP code itself.

By analyzing I need to know exactly how everything is executed and what variables contain and what is outputted to where and what is passed into functions, etc.

Sounds like you are trying to clean the params passed between pages so that your db etc won't be corrupted by injection attacks.

I would have thought regex's and the 'escape string' or 'strip slashes' would do the trick. Sorry I am not proficient enough with php to recall properly, the mysql_escape_string syntax or the 'strip slashes' one.

And if I have misunderstood , apologies for that too.

No need to apologize anything. Not exactly what I want to do, but the principles are the same - I want to know what happens in that PHP code what is passed to where.

The BCompiler link was interesting.
