FrobinRobin,

I looked into your situation a little more, and as far as I can see,
directly, with PHP, there is no clear way to measure bandwidth usage.
However, something I overlooked, apache typically keeps an access_log
file which records all requests and the size of the data transferred
in requests. If you're using apache as your web server, reading from
that file is one possible solution. Other web servers may have similar
logs. I'm not sure if the file records the size of the headers sent
though, which is the same concern I have with what you purposed as a
solution, as well as what Jerry mentioned about binaries.
