Nope, the client will ask for the parts of the file that it needs,
normally downloading a bit before offering to start, and maybe
continuing to download all before the play button is pressed, so the
server can not tell from the download request if the file has actually
been played or not. The server only sees the download request, which
won't indicate if it is being played or not, and in fact it is possible
that the whole file will be downloaded before played, and at some latter
point play might be pressed, which will not send any signal back to the
server, unless you program the player (in flash/javascript/whatever) to
send you a message. The one thing that is fairly certain is that the
player will almost certainly NOT be written in PHP, as PHP is normally a
server side language, and few clients will understand it.
