Actually that's not accurate. The web server does nothing with a file
before it passes it to the PHP engine. PHP gets the entire file, it
simply echo's anything not inside PHP tags.

In general web servers don't know or care about the format of the
files they serve. You configure certain extensions to be passed to
certain modules, even in the case of something like SSI. The web
server itself doesn't usually "parse" any of the files it serves.
