I now encounter a problem with flow control of my program with PHP. This is
very crucial to the design of a pretty big project. This is what I want to
do in the program:
<?php
do_A();
header("Location: ".$result_of_do_A);
do_B();
?>
Since it takes do_B() quite a while to finish, so I want the http client
get the partial result from do_A() by redirect a page to them before start
do_B(). But it seems that the redirection will only occure after the entire
php program finishes, i.e., after do_B(). I sent http request through
browser, curl comman line with -N (no buffer) option and with a perl LWP
program I wrote. All of them suggest that header(), although is put before
do_B() in code, gets executed only after all the php code finished. I add
flush() after header() too, but no work.
My question is: Is there any way that I can return to the client though http
response and then continue my progress with my program?
Thank you very much for your kindly help.
