nice shutdown of CLI script by key press

Alexey Kulentsov

Hi All!

I make command line script operating as demon and want to add
possibility to shutdown it from keyboard. I need to do some things at
shutdown moment. I can break script by Ctrl-break but in this case
destructors and registered shutdown functions are not called.
Is here any method to shutdown script from keyboard with destructors?
"Ctrl-break handler" or something like this?

The most common way to kill daemons is to make them write their PIDs to a
file, then read the file and send a SIGKILL to that PID...

Keeping in mind that daemons run in the background, why do you want to shut
them down with a keystroke??

I want to do it without external utilites. And this script working in
background but with window where I can see log. OS Windows.
In any case - if I will "send a SIGKILL to that PID" that will be with
script? Is here called destructors in this case? If I kill it from task
manager PHP even have no time to reproduce bug #41350. :) Thanks!

Then it isn't running in the background, and it's not a daemon.

OS Windows.

Then I urge you to use the win32service library.

Want to make a daemon? Then make your program behave like one.

Thanks, I didn't know about this extension.

No, really I want to make nice event-driven shutdown, and I afraid
it's impossible in PHP. Thanks in any case.
