Re: [PHP] Windows NT Server, FORK, SOCKETS, and seperate processe s
Either exec(), system(), or one of the functions like them (check the manual)
doesn't wait for anything to return- it just begins executing a new process
and sends it on its way. Perhaps you could use this and just make whatever
you want to do a seperate file?

Yes. Write a daemon which listens on a socket and manages the
communications it gets from the satellite scripts and works the database
for them...
The scripts send off data, and process replies. They don't do the heavy
work...

Subject: [PHP] Windows NT Server, FORK, SOCKETS, and seperate processes
I've got effectivly a glorified chat server which upon the arrival of a
message thorugh a socket connection goes off and runs a bunch of database
processed. My questions is this: How can I seperate the database
processing into a seperate processor process? I really don't want the chat
server to have to wait until after the database processing is done to go
intercept and process another request--this just doesn't seem right. I
want the chat server process to be able to deal with getting and receiving
messages, and another process to deal with the database processing. That
way if one of the processes get's slow, the other isn't affected. Something
like the fork command would work really well, but fork doesn't exist in NT.
Anyone have any ideas?
I'm running Windows NT4.0 sp6a
Apache Server 1.3.xx
MySQL
and of course, PHP 4.2.1

RE: [PHP] Windows NT Server, FORK, SOCKETS, and seperate processe s
I thought about this and it's actually not such a bad idea. I struggle with
it a little though because it seems like kind of a brute force method. I'll
end up with an awful lot of PHP.EXE processes going at the same time.
Although it would get the job done, I'm not certain that it's the right
solution. I was hoping for something a little more elegant. I really like
the pcntl_xxx() functions, but they are only available on UNIX platforms.
And no, UNIX is not an option for this client...they are on Windows and
that's where they're going to stay.
Anyone else have any other ideas?

That's basically what happens in forking and threading. More PHP.EXE
processes appear, even on *nix.

Use fsockopen() to talk to your *OTHER* PHP script waiting in a loop to do
the *real* work.
IE, have a *second* PHP file that runs on yet another socket to do the work.
