> This may be shocking to you, but _all_ code is effectively compiled to "machine code" eventually.

I'm not sure you understood the point. It means nothing to claim that deep down it's all opcodes or electrons flowing. What matters is being able to transform the code targeting the high level interface to the lowest level interface in a way that remains usable and regression-free. Sometimes compilers for widely popular languages introduce bugs and weird behavior too.

I don't think you understood the comments above, but I definitely don't understand your point...

Compilers introduce bugs, yes. Compilers are code, and code can have bugs and regressions.

But the comments above make no mention of bugs are regressions. They said compiling php into machine code is "impossible."

Going form high level interfaces to lower level is the easy part. It's what all interprets and compilers do already.

Having different intermediate forms is also a very common practice. There is nothing special about php here. Except for maybe it's underserved reputation of being an obtuse language.

Such a pedantic response, the archetypical HN comment, I can sense the pretentious smirk on your face while writing it, thanks. Words still mean something, we don't compile a dynamically typed, interpreted scripting language such as PHP for a reason and as it turns out Facebook didn't "compile PHP" either but a dialect of the language.

Facebook transpiled it before using the HHVM.
