I want the http client see the page ( here y.html) immediately after I call
header function, and then close the connectiion, and the function f running
in the background. But trying many many times, the result seems that I have
to either set the time limit to small to send the the html page sooner but
also terminate the background running function which was registered as a
shutdown function, or set the time to long enough for the shutdown function
to finish while keeping the http client waiting until function return.
I doubt that register_shutdown_function meant to behave this way by its
design. I would like to find out what could be wrong of my code,
configuration of php or apache?
My Question is:
What is the correct way to keep the function running after I redirect an
existing page to http client (which I want the client get immediately) and
then immediately close the connection?
Thank you very much.
Given it's a fatal error, it's as bad as a syntax error. It cancels
everything it's doing and leaves.
Remember that, even the shutdown function has to obey the time limit.
