Hello there,
I'm having a somewhat unusual question here, and I cannot find any way
to solve it.
I have a PHP page that displays a message, and then, performs a very
long operation. Note that it displays the message first.
I do not intend to give some feedback to the user when the operation is
done.
I've seen I can use ignore_user_abort() to prevent the user from
stopping the ongoing operation, but that solves only part of my problem.
Because as long as the page is not fully loaded, the mouse cursor in the
user's browser is showing a watch.
So ideally, what I would like is to be able to close the connection from
the server-side, but without using the exit() function, so my script
keeps running afterwards.
I know I could use a system() call to launch another process to do the
processing, but I would like to avoid doing that, because there are many
variables in the context that I cannot easily pass in parameter.
I also tried to use the register_shutdown_function() to perform my
operation after the page is displayed but since PHP 4.1.0, the
connection is closed after the function is called....
Would any of you have an idea on how I could close that connection?
Thanks a lot,
David

If you haven't gone with any of the listed methods yet you could use
fsockopen with a timeout value to accomplish your goal.
frontend.php:
<?php
$fp = fsockopen("localhost", 80);
fwrite($fp, "GET /long_processing_script.php HTTP/1.0\r\n\r\n");
stream_set_timeout($fp, 1);
echo "done!";
?>
long_processing_script.php:
<?php
ignore_user_abort();
set_time_limit(0);
// do stuff here
?>
