Yes, believe it or not, when i was writing this, i thought about a db soln
as well. Just hadnt done it that way back then.
I guess with Linux one could do something like:
shell_exec('{longexecutingprogram -with -params; mysql -uuser -ppass
database query; } &');
Surely it should be possible in windows as well somehow. Does anyone know
how (easily)? I mean i could write a win32 executable that could do it but
that might be overkill.
But still you have to continuously check the database if the value is the
expected which seems kind of unelegant.
Or, you could call a php script at the end like so:
shell_exec('{longexecutingprogram -with -params; php myscript.php with
params; } &');
In myscript.php you could have something like:
<?php
// send request back to user whos ip and headers would have to be saved and
sent.
?>
Would this work? Maybe one could write a library for that directly in php...
So you could actually have a exec_async function without having to write a
php module or something like that. I would be interested in writing a php
module at some point anyway though. I know c(++), so it should be doable.
Is it possible to retrieve the session variables of a user in php cli?
