As it happens, it's well-established that Word documents are basically
just a memory dump of what Word holds in its memory. That's why people
have found the format so difficult to reverse engineer: if your program
structures itself differently internally, then the file format doesn't
make much sense.
That said, most other word processing document formats are different from
the way the document is held in memory.
But anyhow, I fail to see the relevance of this comment. A word processing
document is not a program (though it may contain embedded scripts) --
whether its held in memory in the same format as it is on disk or not
doesn't effect my argument that PHP (and indeed most interpreted
languages) are, in memory, built into an effectively binary format, not
much resembling the script on disk, and then executed.
