Thank you for the info:
I am assuming that sleep uses output buffering, so it doesn't matter
completely when it is called(?)
I probably don't understand your statement/question. Anyhow, sleep()
simply pauses execution of the script, independently of output
buffering.
I just found <http://www.tuxradar.com/practicalphp/8/11/0>, where a
very
simplistic example of flock() in combination with sleep() is given.
Please don't forget to "reply to all" next time.
O.K. I looked at the link and that is essentially what my code is
trying to do:
I.E. obtain a lock, print some text and then call sleep. But the text
that
is supposed to be returned before the call to sleep() doesn't show up
until the first query is done, then the second query returns (with, as
you
indicated, adding a call to flock in the second query handling code.)
That is why I presumed that sleep() was using output buffering.
Anyhow, I am making progress. Thank you for your help
