    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_shutd own_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!!!

      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.
