Writing to Config File
I'm trying to learn how to write my own custom php scripts to modify the config. I've got some code that works wonderfully (it is used for adding users to a specific group). I'm wanting to now start using this in a production environment, but I have some concerns first.
Mostly, how can I ensure that if two people hit this script at the same time that the last one to hit the script will not destroy the first one's settings? I see that there is some locking/unlocking that happens. Can I just check if -1 was returned when calling write_config() and if so, reload the config, reapply my settings, and try again? Would something like that work?
Thanks a ton!
