Starting a PHP Daemon Script sans CLI

[ashore]

All, our open source package is in the hands of n users, some of them quite inexperienced. Some linux servers, some Windows.  Many are hosted, so they don't have ready access to CLI operation. I can't assume that all users are configured with pcntl.

Now I'm contemplating adding some websocket stuff to the mix, and the usual technique requires that the server component/script  be started via a CLI operation.

I'd really, really like to avoid CLI if at possible, and my take is that it's indeed feasible, provided that the following requirements - at least - are honored.

1.  There must be exactly one copy of the script in operation.
2.  The starting process must be atomic.
3.  There must be some termination  method, to ensure that the script doesn't run forever.
4.  The script must run disconnected; i.e., ignore_user_abort() set true.

I'm satisfied I know how to meet these requirements, but what I'm not sure of is how to script the start-up process.  I'll appreciate the collective wisdom here!

Could you just add a script that runs as part of the normal startup collection but that could also be triggered manually if necessary? Something a la init scripts on linux.

Robert, thanks, but my users may not have the tech chops to do that; plenty of noobs in the bunch.  Which is why I'm looking for some simple-minded approach.

Now, for grins, I tried to exec() the would-be daemon, but nothing launched.;  some permissions lacking, I suppose.  Any thoughts on how I might get that to run, even though it might wind up running in my connection context only. 

Or, ????

Plan B:  Do an ajax call to start the daemon, which can run ignoring user abort, with an OK time limit, and can ensure that only one copy is running.

I'll try this and report back result.  AS
