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? -----Original Message----- From: Evan Nemerson [mailto:evan@coeus-group.com] Sent: Monday, July 22, 2002 3:47 PM To: David Buerer; php-general@lists.php.net Subject: 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? On Monday 22 July 2002 15:09 pm, David Buerer wrote: > Yes, that's exactly what I want to do.
