Please help: How to log data before shutdown?

Hi All!

Quick question:
Assume your PHP script is running in the background executing some
long, time consuming process. And while it's running the Host Service
Provider decides to shut down the server for maintenance.

How are running scripts in that case terminated? Will they exit
orderly or will they simply be aborted like pulling the plug?

Will the "register_shutdown_function()" be executed when a server
shut-down exits all running processes?

How can I get my script to write some log data before it is stopped
when the server shuts down or so?

Your help is greatly appreciated!!!
Jerry

Perhaps no, perhaps yes.

Write your script with some regular 'data save' in a file.

You'll need to clarify the problem you're having - scripts can stop running
at any second for countless reasons and they should be able to recover from
that on production sites (i.e. not file-locking anything, not relying on
databases not being in transitional states, etc). Database transactions
(autocommit disabled) is the way to go here. Again, no idea what problem
you're trying to avoid.
