If you need this feature I would suggest you work on it and submit a patch. I
doubt anybody here is going to. We work on things we need ourselves. Usually
for
any long-running things like this we farm it off to something like a Gearman
job
and check for progress via AJAX. Having a frontend Apache process tied up with
something where super accurate client disconnect detection is relevant tends to
be too inefficient.

Sh**, my last comment got silently discarded somehow!!
Please talk to apache developers directly!
If I were developing PHP, I would feel the urge to fix this issue (or call it
"implement this feature" if you want, a basic vital feature whose lack is a
huge
issue) and if this is not possible due to a bug (or design flaw) in Apache I
would strive to have them fix it.

They are basically saying that we could try to hack around Apache and try to
write directly to do direct socket ops on a socket opened and managed by
Apache.
Very bad idea. I don't know of any environment that attempts to do this. See
this conversation about the same issue in Django, for example:
http://stackoverflow.com/questions/6019145/how-do-i-detect-an-aborted-
connection-in-django
This isn't something we are going to address with hacks in PHP.

Response from Apache developers:
https://issues.apache.org/bugzilla/show_bug.cgi?id=54842#c1
I'm not sure I fully understand it but it seems they say there actually IS a
way
PHP can figure out if the connection is closed without attempting to write.

Unbelievable. Then the huge design flaw is in Apache.

Apache handles the communication with the client browser and provides no
mechanism for PHP to discover a client abort except on an actual write.
